Zakhar Dolozhevskiy

I’ve worked with two well-known companies during my employment. On both projects, I’ve been involved as a team leader to organize the work process and support agile methodologies flow.

Each team was of 4-5 front-end or full-stack developers and as a tech leader, I provided code review, mentoring, support, and help with problem-solving (development and communication). I also was involved in building POCs and writing documentation or RFCs of proposed solutions. I’ve go experience in work scope negotiation and pre-sales processes during on-site client visits.

Worked in a web media core team with the main focus on the web calling experience. Implemented reliable and cross-platform solutions for video conferences, screen sharing, media streams transferring, and also covered integration part with other libraries and applications. My area of expertise and responsibility was calls reliability and telemetry gathering (stats of calls, experiments, other valuable data). We’ve used TypeScript, Python, ML, AI, WebRTC, and other less known concepts and tools.
