What I'm looking for

I’m looking for a team where I can lead or own initiatives, build reliable cloud-based backend and data engineering solutions, and keep a strong quality bar through testing, code reviews, and mentorship.

I’m a Senior Python/Go Developer with 10+ years of experience in large international corporations. I’ve built and shipped production cloud services in ML platforms, with a strong focus on code quality, automatic testing, and solving complex technical issues.

At VK Cloud, I led development of new PaaS products for the ML-Platform team, including JupyterHub, MLFlow, Deploy, and Spark on K8s into production. I maintained high reliability by implementing integration and end-to-end testing, running code reviews, mentoring colleagues, organizing meetups, and improving team development processes.
