What I'm looking for

I’m looking for a team where I can lead end-to-end delivery across web, mobile, and backend—building scalable systems, improving performance, and shipping with strong testing and CI/CD, while using AI-assisted workflows and close stakeholder collaboration.

I’m a Senior Full Stack Engineer with 6+ years of experience building production mobile, web, and backend systems. I deliver end-to-end features—taking work from development through production—using React Native, React, Next.js, TypeScript, Node.js, and NestJS, with REST APIs, GraphQL, and real-time services.

Recently, I delivered an AI-powered fintech platform serving 800+ SMEs and a real-time surveillance platform supporting 10,000+ concurrent camera feeds. I focus on scalable backend services, cross-platform mobile architecture, and measurable performance and reliability improvements—leveraging caching, offline-first sync, testing, and CI/CD, with AI-assisted development workflows using Claude and Cursor.
