Ukraine
Summary
👤
Senior🎓
Top SchoolMark Tsyrulnyk is a pragmatic technology leader and co-founder currently serving as CTO at Lumos with nine years of hands-on experience delivering over 50 projects across fintech and blockchain domains. He blends deep systems-level engineering—C++ backend and Rust smart-contract development for Near, Solana, Ethereum and Substrate—with product-oriented architecture and DevOps discipline to take ideas from presale to production. As a former VP of Engineering and fractional CTO, he routinely runs cross-functional agile teams, designs secure CI/CD-cloud infrastructures, and runs client workshops to align functional and non-functional requirements. Mark is as comfortable diving into complex Rust-based DeFi and cross-chain integrations as he is creating feature breakdowns, timelines and resource plans for SMEs. A practical polyglot (Rust, C++, Node.js) who has shipped both legacy C++ refactors and modern blockchain stacks, he looks for small-to-medium projects where boards are willing to evolve in tech and process. An understated strength is his track record of combining architecture leadership with individual contributor work on low-level consensus and reward-logic systems.
