Selected projects
Selected projects showing my approach to frontend architecture, engineering workflows, and technical problem-solving. Each case study describes the context and my contribution and, where I can share them, the decisions behind the implementation.
architecture
A multi-agent code review pipeline for GitLab merge requests, designed and built by me as a personal tool. Specialized agents review each change in parallel, and an orchestrator combines their findings into one structured report. It is designed to surface actionable findings and drop low-value comments before they reach the developer.

A client analytics dashboard for exploring millions of data records through interactive charts, global search, and data tables. I audited the frontend when the project moved from a previous vendor, and since 2023 I have led its distributed team of 10 frontend developers as Tech Lead. It is team-delivered work; my responsibility is frontend architecture quality, delivery coordination, and mentoring.
