SEP 2025 — SEP 2026
Architecting products end-to-end.
I'm a full-stack engineer focused on the intersection of product, performance, and AI. From typed APIs and resilient databases to pixel-perfect interfaces and on-device ML, I design systems that age well.
My work spans Next.js web apps, React Native mobile apps, and LLM-powered features — built on top of Node.js services and PostgreSQL. I care deeply about observability, accessibility, and shipping code humans actually enjoy using.
SSR, RSC, edge functions, and design systems.
Cross-platform RN apps with native-grade UX.
LLM features, embeddings, RAG, and evals.
Typed APIs, queues, and resilient data layers.
