Charles Hapgood-Strickland

Senior Software Developer

"C#"".NET""ABP.io" +17

Veteran software developer with deep expertise in enterprise systems, high-volume data, and legacy modernization. Charles thrives where “old but critical” meets “modern and maintainable” — refactoring VB6-era realities, building robust C#/.NET services, and shaping clean APIs and tools that teams can trust in production. Known for a pragmatic, outcomes-first approach, he emphasizes correctness, traceability, and performance in systems where auditing and data integrity are non-negotiable. He also leads from the front: mentoring developers, improving delivery habits, and designing solutions that scale across sites, devices, and offline/online workflows. He believes the best software should run like a well-tuned engine — smooth, reliable, and built to last. When not crafting elegant code, Charles can be found chasing adrenaline on two wheels, piloting RC helicopters, or flying combat sims — always tinkering, always refining.
