Summary
🤩
Rockstar🎓
Top SchoolRaimis Sakalauskas is a veteran software leader and CTO with two decades of engineering experience and a concentrated focus on iOS since 2015. He has repeatedly taken sole ownership of complex mobile products—most notably maintaining Voloco (50M+ downloads) and executing a critical RevenueCat migration that simplified entitlements for millions of users. Raimis blends hands-on systems design (bridging C/C++ audio engines to Swift) with product-minded architecture, shipping large rewrites, real-time media workflows, and offline-first consumer apps. He co-founded an angel-funded synchronized audio-entertainment startup, building its entire production iOS client, backend, and CI/CD for a remote team. Known for driving stability (raising crash-free sessions from ~98% to >99.9%) and modernizing legacy stacks, he thrives on long-lived codebases and pragmatic migrations. Based in Vilnius with a master’s in Computer Science, he pairs entrepreneurial instincts with deep platform-level technical craft.
