PROFILE
Piotr Żelazko
Piotr developed and maintained core features for the vlayer-xyz/vlayer repository, focusing on secure, verifiable workflows and robust infrastructure. Over nine months, he delivered on-chain guest ID verification, verifiable DNS services, and stable testnet deployments, using Rust, TypeScript, and Solidity. His work included building a Unicode-supporting transcript system, enhancing email verification reliability, and automating web proofing steps in the browser extension. Piotr applied techniques such as dependency injection, CI/CD automation, and role-based access control to improve maintainability and security. His engineering demonstrated depth in backend, blockchain, and front-end integration, resulting in more reliable, scalable, and auditable systems.
