Top SchoolPetri Haikonen is a seasoned PHP developer and Linux sysadmin with 11 years of hands-on experience building browser-based applications and running reliable web services from Espoo, Finland. As Product Owner and Lead Developer at Grinhouse Development he combines technical execution with product stewardship, consistently shipping production-ready features since 2018. His background includes senior PHP and sysadmin roles at Nepton and AminoMOVE, where he managed both application code and the underlying Linux infrastructure. Petri is comfortable across the full stack of web delivery—server ops, backend PHP, and client-facing browser apps—and has a track record of wearing both developer and ops hats to keep systems running. He tends to favor pragmatic, maintainable solutions and brings institutional knowledge from long-term engagements with the same companies. An early-career programmer who evolved into product leadership, he still actively codes and maintains operational systems.
