March 2025 performance summary for a developer's work focusing on cross-language crypto-key management, keystore hardening, and CI/tooling improvements. Highlights include the adoption of the DatabaseKey type across crypto-ffi JS and Kotlin wrappers and interop, migration utilities and tests for database key type changes (JS and Kotlin), and key restructuring in the keystore to enable concurrent migrations. The month also included Uniffi cleanup and removal of scaffolding across core crates, CI/tooling hygiene enhancements, and a security/validation improvement in OpenSSL X509 handling added during this period. Impact and value: - Improved consistency and reliability of key handling across languages (JS, Kotlin, Swift) with a unified DatabaseKey model and signed test coverage. - Faster, more concurrent keystore migrations due to running migrations without a mutex and modularized code paths. - Reduced maintenance burden by removing legacy Uniffi scaffolding and updating to modern tooling. - More robust CI/build processes, with a forked setup-chrome action, explicit paste exceptions, license cleanup, and dependency hygiene. - Strengthened certificate validation in OpenSSL, aligning with RFC 3986 for URIs and expanding test coverage. Technologies and skills demonstrated: - Cross-language interop (Rust, JS, Kotlin, Swift) with DatabaseKey migrations - Uniffi cleanup and multi-crate Rust tooling - CI automation and dependency management (bun, dependabot, forked actions) - Logging and observability improvements and security validation in OpenSSL
