Web scraping, web harvesting, or web data extraction is data scraping used for extracting data from websites. Web scraping software may access the World Wide Web directly using the Hypertext Transfer Protocol, or through a web browser. While web scraping can be done manually by a software user, the term typically refers to automated processes implemented using a bot or web crawler. It is a form of copying, in which specific data is gathered and copied from the web, typically into a central local database or spreadsheet, for later retrieval or analysis.
Web scraping a web page involves fetching it and extracting from it. Fetching is the downloading of a page (which a browser does when you view the page). Therefore, web crawling is a main component of web scraping, to fetch pages for later processing. Once fetched, then extraction can take place. The content of a page may be parsed, searched, reformatted, its data copied into a spreadsheet, and so on. Web scrapers typically take something out of a page, to make use of it for another purpose somewhere else. An example would be to find and copy names and phone numbers, or companies and their URLs, to a list (contact scraping).
Web scraping is used for content scraping, and as a component of applications used for web indexing, web mining and data mining, online price change monitoring and price comparison, product review scraping (to watch the competition), gathering real estate listings, weather data monitoring, website change detection, research, tracking online presence and reputation, web mashup and, web data integration.
Using data scraping you can build sitemaps that will navigate the site and extract the data. Using different type selectors you will navigate the site and extract multiple types of data - text, tables, images, links and more.
Web scraping is the process of automatically mining data or collecting information from the World Wide Web. It is a field with active developments sharing a common goal with the semantic web vision, an ambitious initiative that still requires breakthroughs in text processing, semantic understanding, artificial intelligence and human-computer interactions. Current web scraping solutions range from the ad-hoc, requiring human effort, to fully automated systems that are able to convert entire web sites into structured information, with limitations.
In order to remain competitive, businesses must be able to act quickly and assuredly in the markets. Web Scraping plays a big role in the development of various business organizations that use the services.
The benefits of these services are:
It’s important to note that not all scraper will be ideal fits for every project. For example, those with highly analytical backgrounds in software engineering would be ideal for developing algorithms but may not be the right fit for a data scraping project. That’s why it’s so important to understand what type of scraping expert will bring the most benefit to your company and business goals.
What is the overall learning you hope to find?
By including your goal in the project description, it allows professionals to better understand what type of work is required.

Android is the world’s most popular mobile OS in the mobile market. From phones and watches to cars and TVs, customise your digital life with Android. Many companies preferred Android to begin mobile application development, or entering to the mobile development market because it has a lower cost barrier than iOS.
Android is an open source software stack for a wide range of mobile devices and a corresponding open source project led by Google. The Android Open Source Project (AOSP) repository offer the information and source code you need to create custom variants of the Android stack, port devices and accessories to the Android platform, and ensure your devices meet compatibility requirements.
Now, it’s time to find and hire a developer to turn your creative and amazing ideas into a tangible app. Here’s a look at what Android developers do so you’re prepared to hire the best one for your Android project.
An Android Developer designs and builds advanced applications for the Android platform and has a solid understanding of the full mobile development life-cycle. Through their creations they give the companies they work for the best opportunity to reach users and make an impact worldwide.
An Android developer is in charge of developing applications for devices powered by the Android operating system. They have a strong understanding of the patterns and practices that revolve around such platform. Moreover, they ensure the best possible performance, quality, and responsiveness of the application.
An Android developer takes project specifications and turns them into a tangible application that can be submitted and published in the Google Play store. Most mobile app projects have a design phase, a development phase, and a submission process. Many Android app developers are “full stack,” handling both design, UI and app coding, but you may choose to have both a designer and a programmer on your app’s development team. Just note that UX (user experience) and UI (user interface) design are two different skill sets that are important for the success of your project. If you decide to hire separate contractors for each component, you need one for UX and one for UI.
Android developer skills are separated into three levels depending on their experience. Developers start at the junior phase for the first few years, although the number of apps they’ve developed and the apps’ complexity are far more important when you determine the right developer for your project. After working alongside more experienced developers, they move to the intermediate phase where they can work on more projects independently. After several years working with complex Android applications, a developer is considered senior level. A senior developer can not only code a project, but they can also make decisions about how to design products. All Android developers should be familiar with:
The developer you need will be determined by your project requirements. If you’re creating a new app from scratch, you’ll need a senior-level developer with the experience to take the project from the beginning and see it through to completion. Junior and intermediate level developers are beneficial for small changes, but a senior developer should review the code before it’s put into production.
To find the right freelance developer, you need to write the project with as much detail and documentation as possible. This could be better for developer to choose the right track to start the work. Android Studio makes it easy to create Android apps for various form factors, such as handsets, tablets, TV, and Wear devices.
This article shows you how to start a new Android app project or import an existing project with your developer. Two major things to learn before start to work on the project.
Define your criteria. What kind of freelance developer you need (Junior or Senior) This enables you to describe the tasks to be done with runtime alerts and notification using the Toogit Project Management Tool, this gives you some direction on development level.
Next, Evaluate what type of challenges freelance android developer may face. This evaluation is most important to write the timeline for your project.
Toogit have more experienced android developers. They should guide and develop your project with a professional way. Always remember that more experienced Freelance Android developers on Toogit may charge more even for simple requirements. If you don’t have any understanding of the development process, it might be better to stick with a senior-level developer. A senior-level developer can help guide you through the process.
If you have a smaller budget and simple bug fixes or additions, you can specify that you need a junior-level or intermediate-level developer, but remember that they may not have the skill set to see a larger project through to completion.
The final aspect of your project to mention is its duration (time and cost) it will take to complete. Android development projects can take a week, a month, six months, or more. The duration is often determined by the developer based on your project description, but you can at least provide an estimate or a deadline, if applicable.
Once you get an estimate of how long the project will take, work with your developer to break down the project into releases if you have a flat-rate cost estimate. You can break the project into phases and ask for specific deliverables by particular deadlines.
Example phases include the following deliverables:
How you can write a brief and attractive Android Mobile Application Job description and post it for free? This guide will help you. The way you write a description will determine the quality of developer that you’ll attract. It’s important to write a detailed desciription of job which helps to build the top android the developer interaction in your project and they submit proposals with fairly accurate cost and time estimates on Toogit.
The title of your project description can include the type of development that you need. You know that you need an Freelance Android developer, but do you need a designer and a programmer? Do you need someone who understands a specific framework and the latest versions of android? The title should pull best Freelance Android developers with a specific skill set.
Next, What type of application do you want developed (gaming, educational, entertainment, etc.)? If you have documentation / excel / slides / pdfs or referrence URLs that shows basic wireframes or ideas, you can include these in your project description. Describe the project in simple and straight way with key points & modules it gives a developer a good sense of the work to be done. If you need the developer to sign an agreement, you can also specify this requirement in your description.
Part of your description should also define the deliverables including any designs, APIs, and full source code that can be uploaded to the Google Play Store. The source code is usually delivered using a version control solution such as Git, and then it can be uploaded to Google Play. You might not know the skill set level that you need, but being descriptive will help providers determine if they have the right experience for your project.
Below is a sample of how a project description may appear.

PHP (recursive acronym for PHP: Hypertext Pre-processor) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML.
PHP is one of the main languages used in dynamic web development. It’s one of the oldest language and a common component in the LAMP stack (Linux, Apache, MySQL, PHP). If you want to create a website or any back-end web service, PHP is one of the main languages you can choose from. If you need revisions to an existing application that runs on a Linux server, it’s common for the back-end coding to be done with PHP.
PHP developers are often simply called “back-end engineers.” A PHP developer is responsible for writing server-side web application logic. PHP developers usually develop back-end components, connect the application with the other (often third-party) web services, and support the front-end developers by integrating their work with the application.
They’re turn client’s specifications into a workable, tangible product that runs on a web server. Although PHP can run in a Windows environment, it’s more commonly used on Linux servers with Apache running as the web client. Many PHP developers package their applications this way with Linux and Apache to make it easier for the client to host it.
PHP developers code the functionality and brings an app to life. Collaborating with designers, they ensure that the front-end application is appealing to users. You may find that some PHP developers have front-end design skills, but often times, they work with UI and UX designers to create a user interface that’s engaging and supported by solid back-end functionality.
It is a PHP Developer's job to write, test and maintain the code for web pages and computer graphics programs. They use PHP, a widely used scripting language, to build websites, programs and applications that computers follow to perform functions. They are also responsible for writing, troubleshooting, testing and maintaining the source code for computer programs. If needed, PHP Developers also assist team members in problem solving.
A PHP developer should be able to visualize your application and what you need based on your conversations and documentation (if you have any). They should be able to understand your business so that they can provide you with an application that supports your goals and business logic.
PHP developers mainly create two types of applications: web apps with a database background, and APIs that provide your existing software and data to mobile apps and other developers. PHP code powers the back end of a web app, so a PHP developer will design and architect your code and the way it works to support the front end. APIs are often used when developers or apps need to query your internal data, and they allow you to provide this data to the outside world. For instance, your app might pull a list of tweets from Twitter’s API. A PHP developer will read the API documentation and implement it into your website. APIs are also used with some mobile apps to power the app’s data services.
Deliverables could be full source code files, or some developers help you upload the code to your web server of your choice choice. If you’re building a website from scratch, it’s vital that you choose a developer with the skills necessary to tackle a project from the ground up. A senior-level developer will know how to manage a project (they might assign a project manager), set expectations, estimate costs, and give you organized, scalable code that you can work with for years.
Just like other development areas, PHP developers have a variety of skill sets and levels. Senior-level PHP experts often have several other languages in their arsenal. They should be able to design a full application from the ground up. Junior-level developers have a few years of experience, but they often need to work with, or have their work reviewed by, a senior-level developer to ensure that code is efficient and properly written.
A developer can only do as good of a job as the specifications or information they get from the client. Communication is key so that your PHP developer fully understands your concepts and goals. When you post a project, you must be able to communicate key elements so that you can get the best estimates from the best developers.
Before you post a project request or talk to developers, you should sit down and map out your idea. This can be done using images, presentations, or other types of documentation. For instance, you can draw your own wireframes and then explain each concept in writing. Developers bidding on your project can get a better idea of what needs to be done and estimate far more accurately.
It can be difficult for a client to understand the duration of a project and its cost, but a developer can sit down and discuss project scope, a reasonable timeline, and any deliverables that you can expect during the project’s development process.
Once you know what you want from your end product, it’s time to write your project description. You need to be concise but provide enough detail to attract top developers. You can attach documents and provide video links to your project description to help developers better understand your goals.
Below is one sample of how a PHP project description may look. Keep in mind that many people use the term “job description,” but a full job description is only needed for employees. When engaging a freelancer as an independent contractor, you typically just need a statement of work, job post, or any other document that describes the work to be done.
Title: PHP Developer Needed to Build E-Commerce Website
Description: We need a PHP developer to build an e-commerce platform for our website. We have a rough wireframe document that explains the front end and the back end. We need help determining back-end architecture, so we want a developer to determine the way it will be built. We currently have hosting and need help uploading the code after it’s finished. The e-commerce store will host our product catalogue, take orders, allow customers to sign up, and then send email reminders to customers that left products in their shopping cart.
You can modify this description to better fit what you’re looking for, but it gives the basic requirements that a PHP development project might have.
PHP projects can take a long time, so expect a big project to take several months. PHP projects may require sit-downs to understand your requirements, design, coding, prototyping, and testing. All of these extend the deadline and can require several months for larger projects. A developer might even add a small percentage of time to the duration to ensure that deadlines are met. As with any project, the more descriptive your post is and the more you communicate with your programmer, the smoother the process will be.
