Theo Wiersma
Senior DeveloperTheo is a Senior Developer at DotPerformance, specialising in backend development and system architecture. With more than two decades of experience, he brings the kind of technical depth and forensic attention to detail that complex, foundational work demands.
What makes Theo's background distinctive is where it started. He came to development through project management, which means he understands not just how systems are built but how they fit into the broader context of a project and a business. That perspective shapes how he works, and it shows in the quality of what he produces.
He is a quick thinker with a methodical mind, and the combination makes him effective under pressure. He can diagnose problems fast and resolve them precisely, without cutting corners on the architecture underneath.
Outside of development, Theo is a gifted writer and performer with a deep love of the stage. It is a long way from system architecture, which is perhaps exactly the point.
What does Theo specialise in?
Backend development and system architecture. Theo works on the foundational layer of digital products, building and maintaining the systems that need to perform reliably at scale. His experience across a wide range of coding languages and frameworks means he can find the right solution rather than defaulting to the familiar one.About
