Summary
👤
Senior🎓
Top SchoolDuncan Harris is a seasoned Lead Software Developer with a career dating back to 1988, currently designing high-performance statistical disclosure control systems in Go used by the UK Office for National Statistics. He combines deep system-level expertise—CPU-cache-aware algorithms, vectorized processing, and highly optimized CSV pipelines—with pragmatic product thinking, having delivered both minimal secure REST services and user-friendly GraphQL/UIs. Duncan has led projects across sectors from banking and HR to charity donations and field-service scheduling, and he champions clean code, formalised processes and developer mentoring. Notably, he created a high-level functional language for disclosure rules and a cross-tabulation engine that prioritises real-world performance trade-offs. Based in Chester, he balances technical rigor with curiosity—whether cooking, running or orienteering—and brings measured judgment shaped by decades of delivery and a stint as a cancer carer that reinforced his focus on what is achievable.
