Dream big. Build fast. Ship often.

I started writing code in 2022 and have spent the years since shipping production software β€” from a 13-microservice AI travel marketplace to enterprise AI agents and MCP gateways running on Azure. Currently an Associate Software Engineer on the Agent Accelerator team at BISTEC Global Services, building multi-tenant MCP gateways in .NET 10 that power Microsoft Copilot Studio agents in Teams, and a freelance AI Agent Developer on Upwork shipping RAG systems and n8n automations. I care about clean architecture, predictable systems, and details that hold up under pressure β€” and I write about it on Medium.
