At EVEAD, I’m the main backend engineer for a data-intensive ad-monitoring and influencer-analytics SaaS. I cut ClickHouse CPU by more than half and made the slowest analytics endpoints 14–30× faster while preserving identical results.
I redesigned the export pipeline with size-routed queue lanes, durable job state, and a reconciler, and built an in-house streaming XLSX writer so large exports run in constant memory. I also developed a token-scoped Public Export API and a shared query layer for dashboards and exports.
Before EVEAD, I led the overhaul of a safety-training platform at IZISafety and improved key features’ performance by 25%. At Vo2 Group, I built web, mobile, and backend products, led a financial backend integration, and set up CI/CD pipelines and Jest testing.
