From December 2012 to June 2013 (7 months) UC BerkeleyDeveloper @ Blueprint, Technology for Non-Profits Developed a web application for non-profit organization Foodshift to coordinate deliveries for food recovery when organizations have surplus food. Wrote client-side logic with React and a Rails-based backend. Application allows potential food donors to schedule donations, recipients to be notified of relevant donations, and "shifters" to coordinate the delivery process between donors and recipients.

From January 2013 to April 2013 (4 months) UC BerkeleySoftware Engineer @ Groupon Developed Apache Spark library for writing I/O-heavy streaming applications that ingest large amounts of Kafka data.Built Spark application to persist Kafka data into HDFS efficiently.Migrated Kafka infrastructure across data centers. Coordinated migration steps with other teams dependent on Kafka and built tools necessary to perform migration with no data loss and minimal downtime.Developed Spark library to integrate aggregated application-level metrics with Spark’s internal metrics system (github.com/groupon/spark-metrics).Supported other teams that use our team’s shared Kafka and Hadoop infrastructure by helping investigate application performance, data quality, and other various issues. From August 2015 to December 2016 (1 year 5 months) Palo AltoSoftware Engineering Intern @ Groupon Built a tool using Apache Storm to measure the latencies of events in a data stream at different points in Groupon's data pipeline.Designed and prototyped a system on top of Logstash and Kafka to audit a data stream to monitor if events are successfully being delivered to consumers.Wrote a Java library for Storm to collect and publish aggregated application-level metrics across a topology. From June 2014 to August 2014 (3 months) Palo AltoProgrammer @ Residential Computing, UC Berkeley Designed new hiring administration system with Django. Developed the public-facing job application and the internal administration interface. Maintained legacy Perl web applications. Documented usage of various development tools and processes.
