What I'm looking for

I’m seeking challenging full‑stack or cloud-focused roles at growth-stage teams where I can build scalable, high-performance platforms, mentor engineers, and drive end-to-end delivery.

I am a full-stack software engineer with 4+ years building high-performance frontends (React, Vue, Next.js) and scalable backends using Node.js, TypeScript, and Python. I have led engineering efforts at startups across fintech, edtech, and media delivery, delivering features like adaptive video streaming, crypto payment workflows, and serverless automation.

I design cloud-first platforms with AWS, Docker, CI/CD and performance/SEO optimizations, and I’ve implemented microservices, media processing pipelines (FFmpeg → HLS), and resilient task queues. I thrive in fast-paced teams, prioritize clean, maintainable code, and focus on shipping reliable, user-centered products.
