Helsinki, Finland
Summary
👤
Senior🎓
Top SchoolJaakko Hannikainen is a Senior Software Designer based in Helsinki with 11 years of experience building full-stack and embedded systems across Java, Kotlin, Clojure/Script, TypeScript and Rust. He blends microservice and cloud (AWS) architecture with low-level embedded development, and has held roles from tech lead to security auditor while actively shaping internal functional-programming and engineering communities. As a partner at Bytecraft and long-time contributor at Solita, he routinely ships production systems and tools—some work visible on Solita’s dev blog—and maintains a GitHub presence under @jaakkoha-bytecraft. He pairs a Master’s in Computer Science with practical DevOps, testing and infrastructure experience (Terraform, Docker, CI/CD), making him comfortable spanning product-facing front ends to audited backend systems. An understated strength is his cross-domain fluency: moving between embedded kernel work and high-level web stacks with equal ease.
