What I'm looking for

I’m looking to build and own production web apps and APIs with cross-functional teams—shipping reliable back-end and front-end systems, improving observability/CI/CD, and applying model-backed logic with clean architecture and fast, careful iteration.

I’m a Senior Full-Stack Engineer with 10+ years of experience building production web applications, APIs, and data-driven systems across product, SaaS, and client environments. I’m strongest when combining Node.js, NestJS, Python, React, Next.js, and JavaScript/TypeScript to deliver full feature ownership—from solution design through release—with practical architecture decisions and careful debugging.

In recent roles, I’ve designed scalable backend services and APIs using PostgreSQL, Redis, and AWS-based deployment workflows, including high-volume ingestion, processing, and downstream delivery. I’ve shipped REST and GraphQL endpoints, built webhook/event-driven integrations, improved observability and CI/CD practices, and operationalized model-backed scoring and business logic inside production services—partnering closely across product and analytics to keep releases stable and data accurate.
