Experience
Senior Software Engineer
Aug 2021 — Present
Worked with XFN teams and led a team to shift the Feature Staging Cloud system to use feature coverage drop instead of revenue drop as a primary validation signal to provide better insight into the data quality.• Designed and developed the pipeline creation automation system leveraging multi-category logger without rebuilding the warehouse data landing service for new pipelines to start having data. • Reduced the pipeline landing latency from 4 days down to 1 hour and onboarded all new pipelines to multi-category logger using the pipeline creation automation system. • Improved the service reliability of the warehouse data landing service by preventing the binary size bloating of the previous multiplex logger that is compiled into the landing service. • Utilized Thrift, a RPC framework for scalable cross-language services development, to define data types and build services that work efficiently and seamlessly between C++, Python and PHP.
