Agents, Agents and Agents

I am a Software Engineer at Microsoft, where I co-engineer Agentic solutions alongside Azure’s largest global customers. I don’t just talk about AI; I’m in the trenches solving the messy, real-world problems that come with production-grade agents. My blog is a look behind the curtain—from the friction of aligning with business experts to the technical hurdles of implementation. If you’re looking for honest insights on building AI that actually works (and the lessons learned when it doesn't), you’re in the right place.
