Rockstar🎓
Top SchoolChristopher Kolstad is a Principal Programmer based in Oslo with 13 years of experience designing and delivering scalable backend and full‑stack systems. He currently leads engineering efforts at Unleash-hosted, contributing core features to the popular open-source feature management platform Unleash—spanning API design, database interactions and admin UI improvements. His background includes senior architecture and data engineering roles at Mercell, NAV and FINN.no, where he moved from hands-on development (Solr, Spring, JS) into technical leadership and domain architecture. Christopher blends deep implementation experience with product-minded architecture, often bridging frontend and backend gaps to ship cohesive features. He is comfortable in fast-evolving environments and has a track record of improving developer-facing tooling and operational workflows. Unusually for a principal engineer, he still commits regularly to OSS code that directly shapes product admin UX and feature toggle capabilities.
