What I'm looking for

I want to join remote, product-minded teams where I own features end to end—building secure React/Next.js experiences and deploying scalable, event-driven AWS services—with strong testing culture and CI/CD that keeps quality high.

I ship production web applications end to end, pairing React and Next.js frontends with TypeScript/Node.js services and event-driven serverless backends on AWS. I focus on strong security and reliability—auth hardening, validation, rate limiting, secrets management, and secure deployment practices.

In my current role as a Senior Full-Stack Engineer, I’ve rebuilt and scaled major product surfaces, including real-time NFT portfolio tracking and financial reporting for institutional clients. I redesigned the frontend using Next.js App Router and improved performance (including meaningful bundle reduction), while also architecting AWS media processing pipelines and event-driven achievements/reputation flows with queueing, retries, and idempotent writes.

Across roles, I’ve delivered REST APIs and data models using PostgreSQL, MySQL, MongoDB, and Redis, integrated payment and OAuth providers, and maintained a strong testing culture with unit, integration, and E2E coverage gated by CI/CD. I enjoy working autonomously in remote Agile teams, collaborating clearly with product and design to turn technical plans into outcomes.
