Proliminal AB is Peter Bruinsma's independent consultancy, specializing in performance engineering and systems analysis for complex distributed systems. The work: making the invisible visible. Load testing, flow analysis, observability, decision support — whatever it takes to turn "it's slow and we don't know why" into evidence teams can act on. Peter works early with architects to catch performance risks, and close to production to find the real bottlenecks when real traffic hits. Six years at Biometria on mission-critical forestry logistics platforms handling over a million transactions per day. Before that, 13 years running CraitonTesting — an independent test house that verified hardware and software for international manufacturers, including every Sony-Ericsson handset for the Swedish market over 8 years. Career started at Microsoft in Redmond in 1990, where he designed the Wizard UI pattern during an internship. Today, delivery is fully AI-accelerated — from hypothesis and design through implementation, validation, and production improvement. Proliminal takes its name from liminality — the transformative space between what was and what will be. Whether working on legacy modernization or building new observability platforms, every engagement follows that arc: understand the system, transform it, emerge with clarity. Open source: Agent Lens — a VS Code extension that makes AI coding agents observable. Based in Kramfors, Sweden. Available through the Kvadrat consultant network. proliminal.net
