About
Crafting beautiful applications and delivering exceptional user experiences is what drives me, fueled by a passion to help others and guided by an enthusiasm for open source.I am a Developer Advocate and Software Engineer focused on AI engineering and full-stack development. My work centers on building LLM-powered applications, designing developer tools, and making complex technology approachable, whether that is through code, content, or conversation.My toolkit spans Python, TypeScript, and the modern AI stack (AI agents, MCP, prompt engineering, etc.), with deep experience in FastAPI, Node.js, and cloud platforms. I have also worked across quantum computing (Qiskit), web accessibility, and UI/UX. The full picture matters, from how it works to how it feels.I am always looking for the next thing to build, learn, or share.
