What I do

I build web applications and backend APIs, working across interface design, data modeling, infrastructure, and delivery. My focus is turning requirements into maintainable software through practical engineering and AI-assisted development.

How I build

I follow the AI Development Lifecycle (AIDLC), using AI tools from requirements and design through implementation and delivery. I direct the AI tools and validate their output, taking ownership of engineering decisions and the final software. Explore my process on the homepage and in each project's case study.

What I'm learning

I am actively learning generative AI, agentic AI, and retrieval-augmented generation (RAG), and the Model Context Protocol (MCP), and applying that learning in my projects. I am also developing my technical leadership skills as I grow toward a leadership role. Follow the work in my case studies.
