Rockstar🎓
Top SchoolLukáš Lalinský is a Chief Software Architect and founder with over 20 years of experience designing and shipping backend systems for large internet services, with a strong focus on audio processing, metadata and fingerprinting. He built and operates AcoustID from scratch—implementing audio analysis, fingerprint search, API and public service—and now leads architecture and product engineering at SoundStack to simplify audio creation and monetization. His hands-on background spans C++, Python, PostgreSQL and large-scale deployments, and he has contributed to well-known open-source projects like youtube-dl, Chromaprint and Mutagen, improving audio format handling and robustness. Lukáš combines deep low-level audio expertise with pragmatic system design—he often reshuffles complex code until it “clicks”—and has repeatedly bridged roles from devops to CTO-level architecture. Based in Trenčín, Slovakia, he brings entrepreneurial grit, production-operational experience, and a track record of turning research-grade audio tech into reliable services.
