Summary
🤩
Rockstar🎓
Top SchoolDuncan Stuart is a pragmatic Ruby-focused software engineer and co-founder with 14+ years delivering user-centered web products, from transactional Rails services to WordPress sites. He blends hands-on back-end development and open-source maintenance (notably contributions to the widely used pundit authorization gem) with product thinking, user research and security reviews. Comfortable switching roles—from hiring and bids to acceptance testing—he favours small teams, rapid iterations and constant automation to remove tedious work. An Oxford Maths & Computer Science graduate, he cut his teeth in large public-sector projects before helping scale and spin out product-focused services at dxw and now leads engineering at Varvet. Unusually for a founder, he protects concentrated personal time (Fridays) while remaining open to interesting, small-scale client problems.
