Top SchoolJuha-pekka Jääskeläinen is a seasoned Release Manager with over 20 years of deep expertise in software configuration, CI/CD, integration and end-to-end release processes, currently leading release management at Qvantel from Tampere, Finland. He has driven large-scale delivery transformations at Nokia and Microsoft, where he defined CI-driven release pipelines, cut integration times dramatically, and helped migrate engineering systems to cloud-based binary deliveries. A pragmatic hands-on leader, he blends technical skills (Git, Jenkins, Docker, AWS, Perforce) with team and project leadership, coaching multisite teams across time zones to adopt agile and automated practices. His open-source work includes significant contributions to Nokia’s HEIF library—implementing reader/writer upgrades, performance improvements and C++/Java APIs—showing he still dives into core back-end engineering.
