What I'm looking for

I seek senior engineering roles building scalable SaaS platforms, focusing on performance, secure APIs, CI/CD, mentorship, and collaborative Agile teams.

I am a senior software engineer with strong full-stack experience building scalable SaaS applications and responsive frontends. I design and ship multi-tenant platforms that handle high concurrency and optimize performance across services.

My work spans Node.js, Python (Django, FastAPI), and modern frontend frameworks including React, Next.js, and Vue. I build RESTful and GraphQL APIs, integrate CMS and third-party systems, and implement secure auth (JWT, OAuth2).

I deploy and operate applications on AWS, Vercel, and Netlify using Docker, CI/CD pipelines, and Kubernetes, which has accelerated release cycles and reduced latencies. I also optimize databases and caching layers to improve response times.

I mentor junior engineers and contribute to team processes in Agile/Scrum environments, with focus on maintainable code, testing, and measurable improvements in productivity and user experience.
