Full Stack Web developer

INTRODUCTION

Watch my video-introduction:

Hello my name is Sergei Kozlov. I am a Full Stack Web developer, with over 12 years of computer programming experience.

I created my own project Vide.me alone, which consists of 1,000,000 lines of code written by me personally.

In my current role as a Full Stack Web developer at Vide.me, I have been able to successfully overcome challenges such as:

• Third-party Frameworks showed low efficiency, insufficient for the hardware we used, so I wrote my own Framework, which turned out to be 10% more efficient than others.
• There was no ready-made solution in the world for pipeline processing and uploading video to CDN, and I created my own solution that performs all my tasks.
• Using off-the-shelf cluster solutions (Kubernetes) is expensive and to save money I have set up Docker Swarm failover clusters in the US and Europe, saving myself over $2200 a year.
• In the past, my publicists created content and left forever, so in order to keep them, I created a service that collects geo-data of page visits and turns them into beautiful geo-charts, emails them to authors. This way I retain users 20% more effectively.

I am up to date on all implementations of PHP, JavaScript and Shell programming languages. I have rich experience in using Docker, SQL, DNS, CDN and cloud technologies.

Programming is my passion.

I love complex tasks, because for me it is an opportunity to gain new knowledge and new experience. I use creative solutions to solve every problem. Also in my work I use perseverance. In my practice, there were tasks about which they write on the Internet that there are no solutions to these problems. But I never backed down. I was looking for a solution for 2-3 weeks for 8-10 hours a day. And at the end of a difficult journey, I always find a solution.
