Worked on the keploy/keploy repository to deliver core TLS and proxy enhancements focused on security, performance, and reliability for database traffic. Developed in-protocol TLS handling at the proxy layer for PostgreSQL and MySQL, including server-side TLS upgrades and ALPN support, using Go for backend development and network programming. Refactored proxy connection management with an orchestrator pattern and introduced memory-efficient I/O, session caching, and a TLS handshake store to optimize recording and replay. These changes reduced handshake latency, improved client compatibility, and enforced minimum TLS 1.2, strengthening security and streamlining integration for production deployments involving database management.
