What I'm looking for

I’m seeking senior full-stack or backend roles where I can lead engineering efforts, build scalable real-time and cloud-native systems, integrate AI/automation, and grow within a collaborative, learning-focused team.

I am a full-stack developer with deep expertise in backend systems, mobile (React Native), and modern web technologies like Next.js, React, Django, and Vue. I specialize in building scalable APIs, real-time messaging systems, and cloud-native architectures using AWS, Supabase, PostgreSQL, and Redis.

As a Senior Software Engineer and Technical Team Lead, I have led cross-functional teams, set project roadmaps, and mentored junior developers while delivering high-performance applications and streamlining CI/CD pipelines with Dokku and Docker. I enjoy integrating AI and automation (n8n) into production systems and building user-centric, maintainable codebases.
