Petrut Ivanoiu, Full-stack developer

Full-stack developer in Sibiu

I build web apps, APIs and integrations for startups and small teams. By day I’m a developer at Visma, leading the cloud migration of a payroll-critical app. I started in operations, keeping business-critical systems running through night shifts, so I build software that’s easy to run and hard to break.
