What I'm looking for

I’m looking for a team where I can own end-to-end delivery—performance, testing, deployment, and observability—while building component-driven frontends and scalable back ends. I want strong cross-functional collaboration and measurable impact.

I’m an accomplished Senior Software Engineer with 10 years building full stack web platforms, specializing in React with TypeScript and Next.js architectures, and production back ends with Node.js and Python.

I drive end-to-end delivery—testing, deployment, observability, and collaboration—to improve performance, reliability, and conversion. Recently, I migrated 18 legacy pages into a React + TypeScript + Next.js monorepo, cutting first-byte time by 42%, and modernized component libraries with Storybook (120 reusable components) to reduce feature build time by 55%.

I also strengthen systems through API and data work: implementing GraphQL queries and persisted queries reduced payloads by 48%, adding SSR and edge caching improved TTFB by 60% for 50+ routes, and Redis/PostgreSQL refactors lowered latency from 520ms to 180ms on high-traffic endpoints. I’ve led migrations to microservices, built scalable frontends for 600k monthly sessions, and mentored 6 engineers—always focused on measurable outcomes and maintainable engineering.
