Summary
🤩
RockstarDmitry Chestnykh is a founder and seasoned software engineer with 17 years of experience, currently based in Montenegro and focused on building practical, secure tooling. He created widely used projects such as StableLib and the "I Write Like" invention, and previously founded BlogJet (acquired), demonstrating both product instincts and exit experience. A deep cryptography practitioner, Dmitry has contributed significant implementations to projects like tweetnacl-js and the Go crypto libraries (notably scrypt and blowfish), improving performance and correctness. He combines back-end and DevOps skills—refactoring build tools and adding platform-specific features—while obsessing over "perfect code" and cryptographic soundness. Beyond public projects, his work shows a pattern of shipping robust libraries and thoughtful engineering trade-offs that balance security, portability, and real-world usability.
