Jan 2016 – Jul 2018 · 2 yrs 6 mos · San Francisco Bay Area

• Leading team of 12 software engineers and SREs with responsibility for building a highly-scalable, reliable, and low-latency infrastructure for producing thousands of fraud scores per second.
• Helped implement a replica HBase cluster with automated failover mechanism, which has prevented customer impact during cluster failures
• Integrated ciruit-breaking into the HBase, producing a substantial reduction in downtime
• Led team of 5 to develop Sift's Workflows product, which allows our often non-technical customers to define workflow rules that automatically respond to fraud events without writing code. Today most Sift customers rely on Workflows, making hundreds of automated decisions per second.
