Hi ! Everyone my name is Muhammad Usman . I am a web developer having more than 5 years of experience in developing websites static and dynamic as well. Let me describe what and how i can do for you !! Using a combination of HTML, CSS, and JavaScript, a front-end web developer builds everything a user sees and experiences on a website. They take storyboards, UI/UX mockups, and abstract design concepts and turn them into functioning front-end features like dynamic embedded elements, sliders, drop-down menus, and call to action buttons. Everything from the manner in which web content like articles and videos are displayed to design choices like fonts and color schemes, to the overall layout of a web page must be implemented by a front-end developer. As with any profession, it helps to have a framework for what you should expect to see in the typical front-end web developer’s skillset: Web fundamentals like HTML, JavaScript, and CSS CSS preprocessors like Sass or LESS JavaScript frameworks like AngularJS, React, or Ember etc., or JS-based build tools like Grunt, Gulp, and Bower Libraries like jQuery or Backbone.js Front-end (CSS) frameworks like Foundation or Bootstrap AJAX. A back-end developer builds the web services, APIs, and database management logic that provide the scaffolding upon which the front-end of a website is built. The back-end of a website consists of a database, an application, and a server. A back-end developer is essentially responsible for how data is stored, retrieved, and otherwise managed within a website. The typical back-end developer’s skillset might look something like this: API design and development CRUD (Create, Read, Update, Delete) RESTful Services Web fundamentals like HTML, JavaScript, and CSS Server-side languages like PHP, Python, Ruby, Java, JavaScript, and .Net Database technologies like MySQL, Oracle, PostgreSQL, and MongoDB. Web server technologies like Node.js, J2EE, Apache, Nginx, ISS, etc. Frameworks related to their server-side language of choice like: Express.js, Ruby on Rails, CakePHP, etc. Unit testing, debugging, etc. You can hire me for developing your websites according to your ideas. I have expertise in developing the websites using the Core PHP and its frameworks like Laravel and Codeigniter. Let me introduce about what we offer to our clients 1- HTML 2- CSS 3- JS 4- JQUERY 5- AJAX 6- PHP 7- Mysql 8- Bootsrtap 9- Chart JS 10- Angular 11- CI 12- Laravel 13- Codeigniter 14- Cake PHP 15- Wordpress Experienced in Wordpress/ Joomla/ Magento sites, development, configuration, optimization, migration, custom theme development. Working with various plugins and widgets, customization according to client requirements. Also some other services are ! I have experienced in working with wpml for translating the Languages. Fast way to work with you .. Always looking forward to work with more accuracy and efficiency. Feel free to ask any thing about anything related to translate the languages. Languages English to Arabic Arabic to English English to Danish English to Dutch German to English English to Chinese (Traditional) Chinese (Traditional) to English Translate in many Languages according to your requirements. Basically we have a team of web developers which involves front end developers of the web as well as back end developers ! We always prefer the accuracy of the work for helping our clients ! We always hope for the best for our clients ! Thanks for viewing & reading this !!

Tips to hire an API Developer

In order to clarify what is API development and what does an API developer do lets start with an example. There is a good chance you are already familiar with Candy Crush. In case you dont know it is a very famous app with a great integration to Facebook. Candy Crush doesn't ask us for any Facebook account information when we hit the link 'Connect Facebook'. Instead, it retrieves data from the social network server and allows us to play - all thanks to APIs.
In simple terms, an API enables apps to communicate with each other or to deal with data. It enables a mobile application or platform to share its data with other applications or platforms and automate the user experience without having to involve freelance web developers or to hire android developers for that.
Due to these factors, both app developers and business developers want to focus on the API development process. APIs eliminate the need to create a similar program or platform from scratch; you can use an existing app or platform instead.

Terminologies of API development

To help you understand the concept easier, let's look at a few basic terminologies.
a) API Key
A code passed into the header or parameter of an API request to identify the requester is termed an API Key.
b) Endpoint
When an API interacts with another system, this communication channel on one end is referred to as an Endpoint.
c) JSON
JavaScript Object Notion or JSON is said to be a data format used by APIs to store request parameters, request bodies, and response bodies.
d) GET
The HTTP method used for obtaining resources in RESTful application programming interfaces is called GET.
e) POST
This is the RESTful API's HTTP method for creating resources.
f) OAuth
This is an open authorization framework that gives users access from their side without realizing that credentials are being shared.
g) REST
(Representational state transfer) is an implementation of programming that enables more efficient communications between two devices. The light-weighted system works by offering references to a particular piece of data rather than an entire copy of the data itself when requested.
h) SOAP
or Simple Object Access Protocol, is a protocol used to exchange structured data in computer networks during the execution of web services. The message format and message negotiation and transmission are done through an XML information set and various application layer protocols (such as HTTP and SMTP).
i) Latency
In the process of requesting a response, latency is defined as the time between the request and the response.
j) Rate-Limiting
In API Rate-Limiting, you define how fast users can access APIs by limiting the rate at which they can access them. Basically, it means limiting how many API requests a user may make at a time.
k) API Throttling
This is a way to restrict the use of APIs by users to a certain period of time. This can be used for API limiting. An example would be limiting API requests to 1000 per day. The server will send the user 429 messages as HTTP status along with the message, "Too many requests" if the request hit the 1001 mark.

Working of API

Imagine you are booking a flight through XYZ app/website. After filling out the form - that includes the departure and return dates, city, flight information, and other pertinent information - you submit it. Then, a list of flights, prices, times, and availability of seats in a fraction of a second will be shown to you. But how does it work?
By sending a request to the airline's website, the platform is able to access the airline's database and fetch relevant data via an API. API Integration receives the data from the website and delivers it to the platform, which displays it on the website.

Tools for Developing an API like a PRO

Though there are many API design tools and technologies that can be incorporated into API development, the most popular API tools for developers include the following:
Apigee:
An API management platform operated by Google, helps developers and entrepreneurs succeed with digital transformation by moving toward API integration.
APIMatic and API Transformer:
API development can also be done with these tools. With their professional automatic generation tools, you can produce high-quality SDKs, code snippets, and other format specifications, such as RAML, Blueprint, etc. from API specific formats.
API Science:
This tool is most commonly used for evaluating the performance of internal APIs as well as external APIs.
API Serverless Architecture:
With the help of the cloud-based server infrastructure, freelancers are available to hire as freelance UX designer and UI designer, and to publish and host APIs.
API-Platform:
A freelance PHP developer can provide a framework that is used for building APIs that are open-source.
Auth0:
It is an identity management solution that authenticates and authorizes API calls.
ClearBlade:
It integrates IoT technology into your process via an API management provider.
GitHub:
Developers can manage their code files, pull requests, version control, and comments through this open-source git repository hosting service. They can also create private repositories for their code.
Postman:
It's used by API developers for running, testing, documenting, and evaluating their APIs.
Swagger:
Swagger is an API-development framework that uses the Java programming language. Microsoft and GettyImages are big users of Swagger. However, API technology still has a major gap when it comes to utilizing its perks. Integration with some APIs is a breeze, while with others it is a nightmare.

What are the types of API?

APIs can be classified into the following types:
  • Web service APIs
  • WebSocket APIs
  • Library-based APIs
  • Object remoting APIs
  • Class-based APIs
  • Hardware APIs, etc

benefits of APIs

improved Collaboration:
Most enterprises use more than 1,200 cloud applications (links are external to IBM), many of which are disconnected. Platforms and apps communicate seamlessly through APIs so that they can be integrated. Automation of workflows and improved workplace collaboration are possible thanks to this integration. Many enterprises would suffer from information silos and a lack of connectivity without APIs.
Easier innovation:
APIs enable companies to connect with new freelance business development consultants, offer new services to existing customers, and, ultimately, access new markets that can generate massive returns while enhancing digital transformation. When Stripe began, it was just an API with seven lines of code. Recently, the company has been valued at USD 36 billion (link resides outside of IBM) after partnering with various large companies around the world, diversifying to offer loans and corporate cards.
Monetization of data:
Many companies offer APIs free at first, in order to develop an audience of developers around their brand and partner with potential clients. You can monetize APIs that grant access to digital assets, however, by selling access to them (this is called the API economy). Within 10 months of launching its self-service developer portal to sell a range of API packages, AccuWeather attracted 24,000 developers, sold 11,000 API keys and built a vibrant community.
Added security:
In addition to adding security, APIs create a barrier between your data and a server. Furthermore, API security can be strengthened by implementing API gateways to manage and authenticate traffic, using the use of tokens and signatures, and implementing Transport Layer Security (TLS) encryption.

Reasons why you might want to develop an API

Despite not being comprehensive, this should help you prioritize which APIs are appropriate for your application.
It is probably a good idea to build an API if:
  • One day, you'd like to build a mobile app or desktop application.
  • React or Angular are modern front-end frameworks that you want to use.
  • Your website contains a lot of data that you need to load quickly and without having to refresh.
  • You need the same information in many different places and on many different platforms (ex: a customer-facing web app and an internal dashboard).
  • The data must be accessible only to selected partners or customers.
  • It is up to you to sell direct API access to your customers.
