React/Next.js · NestJS Microservices · AWS · Agentic AI Automation. Senior Full-Stack Developer with 6.5+ years turning complex requirements into fast, reliable products.
I build digital products that are fast, scalable and designed to be used.
I'm a full-stack developer working in React, Next.js and TypeScript on the frontend, NestJS and AWS underneath, leading the frontend team on a multi-service e-commerce/SaaS platform while staying hands-on across its microservices and infrastructure. Lately most of my energy has gone into agentic AI: I built our AI governance framework and CI/CD security scanning so the team can actually let tools like Claude Code speed up development without regressions or security debt sneaking in.
