Summary
👤
Senior🎓
Top SchoolJonas Ellehauge is a Senior Technical Consultant and Principal Frontend Engineer with 11+ years of software experience and two decades of hands-on field operations in Arctic expeditions, SAR and avalanche safety, giving him rare domain credibility in high-stakes operational systems. He designs and delivers spatial, offline-first, and mission-critical platforms—PostGIS, OpenLayers, vector tiles and PWAs—moving ideas from architecture through CI/CD to production. A pragmatic solution architect (IT Architect Foundation trained), Jonas blends frontend mastery in React/TypeScript with platform thinking (Azure, Bicep, monorepos, API-first) and proven delivery across maritime, environmental monitoring and offshore domains. He’s introduced AI-native workflows (Copilot, Claude Code, Augment) to boost developer velocity by ~40% and routinely applies that tooling to accelerate complex migrations and feature delivery. Equally comfortable coding recursive algorithms to tame 90k+ DOM node trees as mentoring engineers to adopt strict TypeScript standards, he pairs deep technical craft with stakeholder-facing roadmaps and phased execution.
