About Robert Felkins — Fractional .NET & Azure Architect

Who you'd be working with

I'm Robert Felkins — founder and principal architect at Felkins Technology Partners, working as Architect4Hire.

I've been building on .NET since version 1.0, and I'm shipping on .NET 10 today. That span is the point: I've seen enough platform cycles to know which "revolutionary" pattern is actually load-bearing and which one is this year's fashion. I stay hands-on — writing production code, mentoring teams, and setting the standards that keep systems performing when the traffic and the team both grow.

The work runs from greenfield cloud-native platforms to enterprise modernization, with a throughline of distributed systems, event-driven design, and — for the last few years — AI-augmented development done with actual rigor. I built and named a framework for that last part (SCRUB), I'm writing a book on it, and the code and prompt libraries are public so you can judge the method before you hire the person.

A few things that tell you more than a skills list

Consolidated 25+ discrete Azure subscriptions into one enterprise-owned landscape at CAI — a cost, security, and reliability win, and a good example of the unglamorous work that saves real money.
Turned a manual enterprise product-recall process into a fully digital workflow at Medline, mentoring three developers through the .NET Core microservices build along the way.
Designed Cosmos DB container strategies — partition keys, indexing, schemas, even Gremlin graph — for high-throughput, multi-tenant scale.
Architected a full-stack .NET 10 / Angular multi-brand content platform on .NET Aspire with a layered prompt-memory system across six brands and a complete developer handoff.
Drove org-wide GitHub Copilot and .NET Aspire adoption through workshops and Lunch & Learns at enterprise scale — the enablement side, not just the architecture side.
