What I'm looking for

I’m looking to build scalable SaaS and cloud-native platforms where I can optimize performance, ship secure high-availability APIs, and apply AI-assisted workflow automation to real business outcomes.

I’m a Senior Full Stack Software Engineer with 9+ years of experience building scalable SaaS platforms, cloud-native applications, and AI-powered systems. I’ve improved API performance by 35% and reduced deployment failures by 40% while delivering enterprise-grade solutions for global teams.

I lead backend services and enterprise APIs (Node.js, Python, FastAPI, PostgreSQL), optimize performance through query tuning and caching (Redis), and design secure, high-availability production features. I also build AI-assisted workflow automation integrating OpenAI APIs with internal systems, using Docker, CI/CD, and microservices to keep systems reliable.
