Top SchoolAnssi Piirainen is a senior software engineer and seasoned technology leader with over two decades of experience building resilient web and video streaming platforms. He blends hands-on engineering—Node.js, Elasticsearch, React and video tech like HLS/RTMP—with leadership roles from CTO to CEO-level integration projects, most notably steering Flowplayer through a cross-border OVP merge. Currently at Snowfox.AI, he’s pivoting that deep streaming and platform experience into AI-driven product work while maintaining a pragmatic, team-first approach. Anssi’s open-source contributions to the popular Flowplayer project show an attention to playback robustness and real-world streaming edge cases (preload, autoplay, fullscreen, RTMP), a detail that underscores his focus on production reliability. Based in Espoo, Finland, he pairs entrepreneurial instincts with a background in quantitative trading and startup founding, making him comfortable at the intersection of product, infrastructure, and rapid iteration.
