Senior Full Stack PHP Developer 7+

I am a full stack developer with over 7 years of professional experience in web development. I have worked for frontend development and backend development for websites and web application development. Having brilliant Mathematics background and web programming, I am able to build any websites and web applications perfectly fit on requirements. I usually have long term clients. I am open to consulting client about software improvements, tweaks that will enhance customers usability. I like more to work on the back-end (gives me more complex problems), but a front-end is also an option after all.

As a full stack developer, I understand really well database architecture specifically MySql is my buddy, but I used also Mongo as far end. For Version Control, I have good experience with Git & Bitbucket. Other than that I must mention long term relationship with external API's like Google APIs, Amazon, and many other ones and that I am totally comfortable with Linux (after all, I am working on it).
