01 / about

Full-stack engineer with a GenAI focus.

I'm a full-stack engineer who designs and delivers dynamic, scalable, high-performance web applications, from backend architecture through to intuitive frontends. I work across Node.js, Go, Python, PHP and React.

Lately my focus is GenAI: RAG chatbots with conversational memory, MCP tooling and AI agents on AWS Bedrock. I use modern AI frameworks and LLMs to build adaptive, user-centric products that pair new ideas with practical functionality.

As a Lead Engineer, I drive the company-wide AI SDLC framework and work with teams across projects to bring AI into how they plan, build, test and ship, resulting in a 3x productivity boost measured by story points. I mentor engineers, care about clear communication, and keep learning so I can stay ahead of emerging technology.
