What I'm looking for

I seek a role owning end-to-end product delivery in AI/SaaS, working with modern cloud stacks, real-time systems, and collaborative teams that value technical leadership and impact-driven results.

I am a Senior Full-Stack Engineer with 8+ years building scalable SaaS products and AI-powered automation systems, experienced in RAG pipelines, AI agent development, and prompt engineering. I have a proven track record integrating CRMs, third-party APIs, and cloud infrastructure (AWS/GCP) in fast-moving startup and enterprise environments.

I own product delivery end-to-end from architecture to client communication, having engineered full-stack applications with Python, React, Rust and Node.js, built real-time IoT dashboards, re-architected document ingestion to cut processing time dramatically, and led DevEx modernization with Docker and Terraform while mentoring teams on CI/CD best practices.
