What I'm looking for

I seek a collaborative engineering role where I can lead platform and reliability work, mentor teams, and ship scalable, observable systems.

I am a full‑stack engineer with 6+ years building data‑intensive, user‑facing platforms end‑to‑end, with deep experience in React/TypeScript, Node.js/GraphQL, MongoDB and cloud container platforms. I own features from discovery and design through rollout, instrumentation and iteration with a focus on reliability and performance.

At my current role I architected a unified content platform powering 20k+ learning assets, launched engagement systems (points, in‑platform store, avatars) and led a staged TypeScript migration across services while improving CI safety and developer workflows. I also built event‑driven pipelines, LLM‑powered content generation, and internal tooling to streamline operations.

I seek to leverage my technical foundation and leadership to deliver value through collaborative development, advanced toolchains and strong observability, mentor teams, and drive dependable product outcomes.
