Dear Sir/Ma'am,
With my current skill and knowledge, I think I am eligible for this position. Last year summer, I have worked as a freelancer developer. In this meantime, I have developed a few websites and applications like music search engine, Instagram analytics, a keylogger and a social networking website. I have got many errors and problem. But from this, I have learned how to handle the errors and fix bugs. I am a quick learner and I am willing to learn new technology, programming language, data structure and algorithm to make my future work fast and efficient or to do a specific task. Last year August, I got two internships at two companies as backend developer using Golang for developing an analytics application and Research and Analytics developer for building a database. It used to show analytics about their development using various kind of tools that they are using in their development process.
As you need someone who has knowledge of PHP, HTML, JavaScript, Angular 4, React Js, Python, jQuery, MongoDB, Node.js, and MySQL. I have worked on all of them and know how I able to solve a problem.
