I have spent 14 years building product features at scale — from automotive telemetry systems at Bosch to high-traffic SaaS at Allianz. Performance has always been part of my DNA: I profile before I optimise, measure before I change, and I never guess. Cursor helps me iterate on optimisation ideas faster — trying different caching strategies, query patterns, and indexing approaches without getting bogged down in boilerplate.

My sweet spot is feature development with a performance lens: new user flows, API endpoints, and data-heavy UIs that need to stay responsive under load. I have optimised PostgreSQL queries that were taking 8 seconds down to 80ms, reduced React bundle sizes by 60%, and designed caching layers that cut API latency by 70%. I use Redis, CDN, and database indexing as first-class tools.

I work with TypeScript, Node.js, React, and PostgreSQL. I care about observability: metrics, tracing, and dashboards that tell you when something is slow before users complain.
