Robert L.Private profile: Upwork shows its earnings only to signed-in members, so we check it every few weeks, not daily. MRR here is a rough estimate (Upwork's six-month earnings ÷ months active). Last read Nov 5, 2026.

I have multiple 2,000 to 6,000+ hour contracts on Upwork because I build .NET and Angular systems that scale without needing rewrites, and I rescue the ones that weren't built that way. 20+ production launches in the last 10 years. Project experience from $500K to $1.3M and teams from 2 to 60 engineers. .NET since 2009 and Angular since 2019, with work for Unilever, Greyhound and the American Airlines Pilots Association. I am a US-based senior .NET and Angular architect. I've built software professionally since 2009, from small companies to large corporations, and I was a consultant at Capgemini, where I also ran technical interviews to hire engineers. I build on .NET, Angular, Azure and SQL Server, and I've stayed on that stack since 2009 instead of rotating through frameworks. That depth is why I can find what's wrong with a system quickly. A framework is a tool; what matters is how the system handles state, scales under load, and securely processes data. I also rescue software that never shipped, or shipped and keeps breaking: I stabilize the app, fix the architecture, and right-size the team so it costs less to run. One team's engineering cost went from $48K to $8.7K a month, and a project that was 6 months late was finished in 3. I hold a Bachelor's degree in Economics with Systems Analysis from Southern Methodist University, which is why I think about what software costs you, not just how it's built. My architecture work follows established patterns from Martin Fowler's Patterns of Enterprise Application Architecture and Gregor Hohpe's Enterprise Integration Patterns, and I regularly mentor newer engineers. Not on .NET or Angular? I'll tell you right away.
