What I'm looking for

I'm open to remote .NET or platform engineering opportunities where I can build and scale durable infrastructure-level systems.

At HRM Enterprises, I build the infrastructure other developers build on. I designed and maintain AppCommonCore, a production C# execution framework used across every internal application.

I also established zero-config engineering standards for new projects, including GitHub Actions CI/CD, StyleCop, CSharpier, and AI agent instruction contracts. I've shipped six production integrations spanning eBay, Walmart, Shopify, Verkada, SMSST, and OrderShipments CV3, alongside Power BI reporting pipelines and company DAX standards.

Previously, I modernized a law firm's legacy stack as its sole developer, cutting manual workloads by 90%+ and reducing a multi-hour legal-document process to minutes. At Eurofins TestOil, I refactored critical intranet components to reduce CRAP scores from 200+ to below 20.
