About

I'm a full-stack developer based in the GTA, Ontario. I enjoy taking messy, real-world problems and turning them into systems that actually work in production. I've been building software for 5+ years, mostly in environments where reliability, security, and data accuracy really matter.

In my current role, I build and maintain applications used by 4,000+ employees and 30,000+ students. That work includes internal portals, helpdesk and asset-management systems, reporting pipelines and system integrations. Working in the public sector has made me very intentional about security, compliance, performance, and cost.

I use AI pragmatically, not as a buzzword. I've built LLM-based solutions for things like PII redaction and classification, including a redaction system that saved $10,000+ compared to commercial alternatives. I enjoy experimenting, measuring cost vs. accuracy, and picking the simplest solution that works.

My main stack is C# and ASP.NET Core (MVC, Blazor, EF Core, SQL Server), with React on the frontend. I also use Python for AI workflows and agents (LangGraph, LangChain, vLLM). I care a more about observability, clean data models, and systems that are easy to operate after they're deployed.
