Rockstar🎓
Top SchoolMiroslav Bajtoš is a Staff Software Engineer with 14 years of experience turning ambiguous technical visions into hardened, production-ready distributed systems. He led protocol design and implementation for Filecoin SPARK at Protocol Labs and Space Meridian, operating a permissionless network with 15k+ daily active nodes and driving a 15× improvement in retrieval success while cutting memory and cost dramatically. A hands-on architect and founder, he authors ADRs, roadmaps and runbooks, ships cross-platform runtimes (Zinnia) and fast MVPs (FilBeam), and mentors small distributed teams to deliver high-velocity, low-fragility outcomes. His roots in open source include major contributions to Node.js core and leadership of the LoopBack framework at IBM, with deep expertise in TypeScript/Node.js, Rust and PostgreSQL. He favors remote-first engineering cultures, TDD and AI-assisted workflows to keep feedback loops short and maintenance costs low. An often-overlooked strength is his ability to translate protocol-level threat models into operational observability and cost optimisations that scale in the wild.
