EyeRide

https://eyeride.io/
The cloud video streaming and processing system we developed as a team helped EyeRide startup to grow and gain more customers. The video streaming feature allowed customers not only to track their vehicle's location but also to monitor road accidents and driver's fatigue.

As a team we learned how to deal with video streaming, how to process video, and how to make it play in a browser via WebRTC; we learned how to build and orchestrate cloud clusters.

This project is the largest project I have contributed so far.

MegaFon

This is the eDoc workflow system that we developed while at MegaFon. As a personal note, it was my first big project and I'm really proud of it. This system enabled the company to save money on expensive third-party software, it works fast, and it 100% fits the needs of the company.

We learned a lot while developing the project: how to optimize the database load, how to make a user-friendly UX/UI, and how to keep track of over 3 millions workflows that ran during the three-year period of my full-time position at the company.
