What I'm looking for

I’m looking for a role where I can lead end-to-end delivery, shape scalable architecture, and mentor teams—using modern React/TypeScript and Node.js/NestJS in real production environments.

I’m a Senior Full-Stack Developer and Tech Lead with 5+ years of experience building scalable web applications and leading cross-functional engineering teams. I specialize in React, Next.js, Angular, TypeScript, Node.js, and NestJS, with a strong focus on software architecture, Docker, AWS, and monorepo design.

I’ve delivered production systems in healthcare, legal, and financial domains, including systems serving 500+ users. I’ve led architecture work such as migrating a legacy Oracle APEX system to modern Angular, mentoring through structured code reviews, and designing event-driven telemetry using IndexedDB and Beacon API. I also built ETL pipelines with Python and supported pragmatic delivery using Agile (Scrum/Kanban).
