Top SchoolHenk Kelder is a veteran software architect and developer with over 40 years of coding experience and a 35+ year professional track record designing and troubleshooting complex systems. He has led architecture and application development for major clients (including government portals and mortgage platforms), built high-traffic consumer sites and cross-platform mobile apps, and performs code audits and system migrations with pragmatic attention to reliability. Comfortable across C#, .NET, SQL Server, frontend frameworks and legacy languages, he blends hands-on implementation with system-level thinking.
