Mikhail Vagner

I’m a Frontend / Full-Stack engineer with 5+ years building and scaling web products. I focus on frontend architecture, usability, and end-to-end feature ownership in fast-moving environments.

At CyberHULL, I’ve automated development workflows with an LLM-driven 9-step Git Flow pipeline (8 AI agents) for code generation, branch creation, PR drafting, and validation, and I added AI-assisted PR review that reduced manual review time by ~35%. I also refactored 160,000+ lines of legacy data pipeline code, integrating automated unit tests for nearly 85% of the application.

I care deeply about reliability and release safety—debugging and stabilizing AWS infrastructure, improving authentication via programmatic temporary AWS credentials, and optimizing MySQL performance through query analysis and schema migrations. I’ve also managed 50+ production releases, mentored engineers, and delivered demos and documentation to help teams onboard and move faster.
