Summary
👤
Senior🎓
Top SchoolPeter Hillerström is a senior software engineer based in Helsinki with 15+ years of professional experience building fast, accessible and polished web and mobile applications. He blends a graphic design background with deep frontend expertise in modern JS/TS frameworks (Svelte, Vue, Angular) and solid backend skills in Python/Django, Rails and Node, often owning full-stack product development in early-stage startups. Comfortable as the sole technical lead, he has shipped geolocation, mapping and media-heavy SaaS features, designed event-driven architectures and led migrations to modern build pipelines and CI/CD. He values simple, well-crafted code, user-centered design and automated testing, and mentors junior engineers while collaborating closely with nontechnical stakeholders. Equally at home in systems-level work, his polyglot programming experience spans Haskell, Rust, Elixir and many scripting languages, reflecting a long-standing curiosity about functional and reactive programming. A pragmatic remote-first developer, he has driven product and process improvements—like issue-prioritization systems and API design—while maintaining an eye for typography, performance and accessibility.
