About Me
I'm a Full Stack .NET Developer with 13+ years of experience, but don't let "full stack" fool you. I'm 80% backend, 20% frontend. My world lives in APIs, distributed systems, cloud infrastructure, and now Generative AI.
Currently at UWM (United Wholesale Mortgage), I work on Chat UWM, an AI platform that includes an AI Marketplace and Agent Builder. Agents are plan-driven and run through LEGO, our internal modular microservices system. LEGO includes the Orchestrator, which implements Semantic Kernel and coordinates all the underlying services. Each agent can use a different LLM based on its use case, support RAG or direct chat, and is access-controlled within the marketplace.
Before that, I spent 7 years at BI Worldwide in the Loyalty & Rewards domain where I built financial transaction systems from scratch, designed microservices on AWS EKS, shipped a real-time ETL pipeline with RabbitMQ and Lambda, and cut CI/CD release cycles by 83%. I also mentored 8+ junior developers and drove architecture decisions across the engineering org.
Earlier career took me through Healthcare, Insurance, and IT Infrastructure at companies like Harman International, BT ESERV, and Virinchi & Asclepios, giving me a broad foundation in enterprise patterns, database optimization, and domain-driven thinking. I apply DDD, CQRS, and Clean Architecture so systems remain maintainable long after the first release.

What I Believe In
Principles that guide how I build software
Architecture first
Good software starts with good design. I invest time in understanding the problem before writing the first line of code.
Simplicity over cleverness
The best code is code that the next developer can understand immediately. I write for humans, not compilers.
Continuous learning
13+ years in and I still treat every project as a chance to learn something new, whether it's a pattern, a tool, or a domain.
Mentoring matters
I've always believed that growing your team is as important as growing the product. Sharing knowledge multiplies impact.
Test-driven confidence
TDD isn't just a methodology. It's a mindset that forces you to think clearly about requirements before implementation.
Business impact
Great engineering means nothing if it doesn't solve real problems. I keep business outcomes at the center of every decision.
