Summary

Rockstar🎓
Top SchoolGustav Larsson is a Senior Software Engineer based in Gothenburg with a decade of experience building full-stack web applications and leading engineering efforts. He currently contributes at Open Collective, where his backend work on the GraphQL API and virtual card features and frontend improvements have strengthened financial workflows and UX for an active open-source platform. As Lead Engineer at Cobudget and founder of multiple side projects (PairHub, Freewriter), he blends product-minded engineering with hands-on implementation across React/Next.js, Node, PostgreSQL and GraphQL. He’s comfortable switching between backend performance work and subtle frontend UX enhancements—examples include time-series transaction stats, expense filtering, keyboard-driven transcription UI and auto-scrolling. A self-starter who’s been freelancing since 2011, Gustav pairs startup grit and academic entrepreneurship training from Chalmers with sustained open-source contributions. Colleagues would call him pragmatic, detail-oriented, and focused on shipping features that improve collaborator workflows.
