What I'm looking for

I’m looking to lead end-to-end product engineering on scalable full stack systems—building fast, accessible UIs, reliable microservices, and AI/LLM features. I value strong observability, security-first practices, and close cross-functional collaboration.

I’m a Senior Full Stack Engineer with 11+ years of experience building modern web applications, scalable backend systems, and AI-powered platforms across fintech, civic technology, SaaS, and education domains. I focus on delivering high-performance user experiences and production-grade APIs that teams can trust.

In recent roles, I’ve built and deployed scalable full stack applications using React, TypeScript, Node.js, and FastAPI, along with cloud-native microservices and event-driven architectures. I’ve led end-to-end engineering initiatives that improved usability and accessibility, reduced latency, and strengthened observability through structured logging, monitoring, and distributed tracing.

I also bring deep expertise integrating AI/LLM capabilities (including OpenAI APIs and LLM integration) alongside practical system design—authentication, authorization, RBAC, and audit logging. I enjoy collaborating closely with product, design, and infrastructure teams to ship resilient platforms, improve operational efficiency, and continuously raise engineering quality.
