Summary
👤
Senior🎓
Top SchoolKacper Nowosielski is a Senior Fullstack Developer based in Helsinki with five years of hands-on experience delivering web architectures, API integrations, and headless Drupal solutions using React, Next.js and Kubernetes. He combines deep implementation skills with client-facing consulting and tech-leading, helping shape architecture choices and guiding project teams toward practical, maintainable outcomes. Kacper has a track record of mentoring juniors, building component-driven design systems (Storybook) and owning end-to-end delivery from spec to CI/CD. Comfortable across PHP, modern JS frameworks and cloud-native deployments, he’s equally at home optimizing Drupal backends as crafting frontend experiences. Colleagues describe him as intensely focused on delivery and continuously curious—someone who deliberately turns client requirements into pragmatic technical roadmaps.
