• Architected an asynchronous API service in Golang, deprecating legacy synchronous bottlenecks to sustain 1,300 RPS while strictly maintaining sub-100ms latency. • Designed a highly scalable analytics pipeline indexing 15 million sessions per client daily, leveraging Protobufs and aggressive compression to reduce memory footprint by 90%. • Led zero-trust architecture initiatives by reverse-engineering competitor SDKs and migrating critical risk-flag computations to native C/C++ (JNI) to thwart advanced hooking frameworks. • Engineered an asynchronous Python-based API testing framework leveraging declarative TOML definitions and jq validations; integrated it into organizational CI/CD pipelines to execute parallelized topological execution layers, completely automating endpoint validation and eliminating manual QA bottlenecks.
