What I'm looking for

I’m looking for a remote-friendly role where I can lead cross-functional full-stack delivery, build reliable integrations and APIs, and keep quality high through strong testing, clean architecture, and performance ownership.

I’m a full-stack developer and team lead with 7+ years of experience shipping web products, growing from Junior Frontend Developer to Full-Stack Team Lead within a single product company.

I’m comfortable across the stack—frontend and backend—with hands-on leadership of cross-functional teams and strong ownership of delivery. I’ve shipped multiple B2B SaaS products in the telecom domain, built REST APIs, and architected event-driven microservice integrations.

I also focus heavily on quality and maintainability: I’ve led rewrites to modern React SPAs, introduced integration/unit testing, and established architecture patterns, code review standards, and testing practices that drove over 80% test coverage.

As an independent developer, I left full-time work to build and launch software products, keeping the same bias toward execution, customer impact, and pragmatic engineering.
