What I'm looking for

I’m looking for a senior role building secure, cloud-native microservices and scalable web apps, where I can own end-to-end delivery, improve reliability/performance, and apply AI automation to reduce repetitive operational work.

I’m a Senior Full-Stack Engineer with 8+ years building enterprise-grade distributed systems and scalable web applications. I focus on microservices architecture, REST API design, real-time systems, and workflow automation—delivering production platforms across healthcare, logistics, and enterprise operations.

Across my roles, I’ve led end-to-end development of operations and logistics platforms, integrating AI-powered workflow assistance with OpenAI APIs and training ML models using Python, PyTorch, and Scikit-learn to improve decision-support. I also drive cloud-native deployments with Docker, Kubernetes, and AWS, and I optimize performance and reliability through layered backend design, secure authentication/authorization, and strong observability practices.
