Markus Heien

Only developer at a student organisation with four campuses. I build the platform, run it on Docker, Traefik and self-hosted Appwrite, and look after the Microsoft 365 tenant.

• Replaced paid WordPress sites and plugins with BISO Sites, a Next.js and TypeScript monorepo: public site, admin platform and REST API (~200k lines, ~2,600 tests).
• Built webshop and membership payments on Vipps and Stripe, with idempotent order reconciliation and automatic posting of orders, refunds and expense claims to 24SevenOffice.
• Built the recruitment system that hires hundreds of volunteers and staff a year, with interview booking through Microsoft Graph and AI screening that removes personal data first.
• Rebuilt the student app in Flutter for ~5,000 registered users, adding Apple and Google Wallet membership cards, receipt scanning and automated store releases.
• Tied admin permissions to Entra ID groups so access follows people’s roles across campuses, and moved yearly Microsoft 365 account handovers into the admin platform.

• Built an election system in PHP that replaced a NOK 30,000-a-year licence.
• Built BISO’s first mobile app (React Native, Expo) to replace a ten-step expense form.

• Automated monthly settlements for 300+ stores with VBA, from hours of manual work to minutes.
