ABOUT ME
.NET / C# Expert and Mentor
.NET / C# Expert and Mentor

Senior .NET engineer and educator. I ship production code by day and have taught 500,000+ developers how to do the same.

I build last-mile delivery systems at Better Trucks in C#/.NET. I own Checkpoint, our AI-driven address validation and geocoding pipeline (EF Core, PostgreSQL, Google Cloud), winner of "Last Mile Innovation of the Year" at the 2025 SupplyTech Breakthrough Awards and featured on the Google Maps Platform blog.

I have authored 19 Pluralsight courses, 20+ LinkedIn Learning courses, and 10+ Udemy courses with 109,000+ learners, plus free tutorials on YouTube (youtube.com/@dotnethow). Teaching at this scale means I explain things clearly and fast, which is exactly what you want in a session.

What I can help you with:

  • C# and .NET: ASP.NET Core, Web API, EF Core
  • Databases: PostgreSQL, MySQL, SQL Server
  • Cloud: Google Cloud (Pub/Sub, Cloud Run), Docker, CI/CD
  • Debugging, code review, and architecture feedback on real projects
  • Interview prep and career guidance for .NET roles

Also: Microsoft Certified Trainer, 2x MCSD, founder of ReSlug.

Book a session and bring your actual code. We'll fix the problem and you'll understand why it broke.

Ervis was fantastic, he took time out of his day to solve my issue when no one else I had tried could fix my issue. Highly recommended
