In February 2026, I delivered a performance-focused enhancement for the Tyk gateway: Efficient Plugin Verification with Incremental Hashing and Skip-Verification Config. The change reduces resource usage during plugin bundle verification by processing MD5 and SHA256 hashes incrementally and introduces a new skip_verify_existing_plugin_bundle configuration to bypass verification for existing bundles on disk (TYK_GW_SKIPVERIFYEXISTINGPLUGINBUNDLE). This work addresses a CRITICAL regression tracked as TT-16532, where Bundle Verification significantly increased resource consumption. The implementation includes extended tests and benchmarks (TestBundle_Verify) that validate behavior across scenarios and show improved timings and meaningful memory reductions for large/multi-file bundles, while maintaining safe defaults. Business value: lower CPU/memory usage during startup and plugin reload, faster verification, and improved gateway scalability. Technologies/skills demonstrated: Go, cryptographic hashing, incremental computation, feature flag/config, environment variable integration, test/benchmark development, and performance analysis.

January 2026: Delivered a critical stability improvement for the Tyk Gateway by fixing a JWKS cache memory leak and hardening the cache lifecycle. Implemented atomic delete/close for cache instances, optimized the load/create path to avoid races, and added proactive cleanup during Init. These changes stabilized memory usage under load tests and reduced the risk of leaks during JWKS operations, aligning with TT-16468. Validation included local load testing and profiling artifacts (pprof reports).
