In March 2025, delivered targeted documentation updates and security hardening across three Babylon projects, enhancing onboarding, developer experience, and operational resilience. Key outcomes include: networks — BLS key management and validator configuration documentation update clarifying epoch-end voting and Bitcoin ledger checkpointing; finality-provider — consolidated release notes and slashing protection docs with improved security guidance leading up to v1.0.0-rc.2; Babylon — Incentive Module API documentation and endpoints aligned with Swagger; crypto hardening for PoP separation, 32-byte BLS keys (ERC-2335), and removal of unsafe key generation paths. These efforts reduce onboarding time, minimize signing risks, and improve readiness for releases. Technologies/skills demonstrated include OpenAPI/Swagger documentation, security best practices (domain separation, key-length validation), changelog management, and backport/documentation discipline.
