About me

A bit of background

Senior Full-Stack Engineer with 10+ years building scalable web applications, REST APIs, and cloud-native systems across fintech, healthcare, and enterprise sectors. Using React, Angular, Node.js, and Python, I've worked across the full stack — from database design to cloud infrastructure on Azure and AWS.

In recent years I've become an expert in generative AI: designing secure, production-ready LLM workflows, building MCP servers, and orchestrating multi-agent systems. I care a lot about code quality, security, and delivering things that actually work in the real world.

I thrive in cross-functional teams, value clear communication, and care deeply about security, code quality, and delivering software that genuinely works at scale.
