Senior🎓
Top SchoolOlli-pekka Wallin is a Senior Engineer based in Oulu, Finland, with over 25 years of diverse professional experience and 12 years focused in software roles across embedded systems, cybersecurity, and full-stack development. He currently contributes to Bittium and Bittium Biosignals, bringing deep system-level expertise and a pragmatic approach to building reliable, medical- and security-oriented software. His background spans startups and mature companies—roles from system designer to senior software engineer—so he comfortably navigates low-level firmware, Linux server administration, and frontend/backend stacks. Colleagues rely on him for practical solutions to complex integration challenges and for translating long-term product needs into maintainable code.

Based in northern Finland, he blends institutional knowledge with hands-on engineering discipline suited to safety- and security-sensitive products.
