What I'm looking for

I seek roles where I can improve performance and reliability, optimize cloud costs, lead cross-functional delivery, and scale user-focused products.

I am a full-stack developer and technical product manager with hands-on experience building scalable web applications, optimizing cloud infrastructure, and shipping products that grow users and revenue. I focus on measurable impact—reducing response times, cutting cloud costs, and improving deployment velocity.

My recent work includes backend performance tuning that cut p90 response times from 8s to 628ms, CI/CD improvements that sped builds 4x, and infrastructure optimizations that reduced annual cloud spend by 33%. I also led product teams to deliver web apps that increased MAU 2.5x and doubled MRR contributions.

I bring a practical technical stack spanning JavaScript/TypeScript, Python, and Go, plus frameworks like React, Next.js, Svelte, and FastAPI, combined with AWS and IaC (Pulumi) experience to deliver performant, cost-effective, and maintainable systems.
