Harshal Parekh EXPERIENCE

Visa, Inc. / Sr. Software Developer Austin / Feb 2020 - Present “Athena” / Product Owner - one stop gateway validation

• Fully automated tool generating rule-based, gateway and field agnostic, comprehensive test cases. • Verifies rule logic; auto-generates test data for 100% rule coverage. • Request-caching to process the difference only for future requests.

“Minerva” / Full Stack - one stop helper utility • Run standalone tests, get responses/errors from server logs, check server status, format converters (JSON to XML, etc.) and beautifiers. • Users can create new environments and save configurations.

“Internship” Summer 2019 Athena (POC): reduced manual effort to zero and TTM by 30%.

Credit Suisse / Technology Analyst Intern India / Summer 2017 Automated 6 tasks - traversing through 4 tools and generating the final report - saving 1.5 hours daily.

PROJECTS

Twitter Analytics on AWS Spring 2019 • A scalable and reliable web service on ~200 million tweets. • Performed ETL into MySQL and HBase; designed and optimized the schemas that increased throughput; profiling identified bottlenecks. • User recommendation based on interactions and text (15,000 RPS) • Time & user ranged topic words extraction using TF-IDF (5,000 RPS)

Cab Service on GCP April 2019 • Real-time customer-driver matching and ad-serving Kafka and Samza system on a YARN cluster to join and process multiple streams. • Feature extraction and hyper-parameter tuning of XGBoost model that predicted fare and suggested places using a pipeline of ML APIs.

Multi-threading and Consistency March 2019 Extended a distributed key-value store with replication schemes - strong and eventual consistency at different geographical locations.

Social Networking Timeline February 2019 Reddit timeline page with MySQL, MongoDB and Neo4j backends.

Knowledge Discovery on Health Records Undergrad Research 96% accuracy on CDC sourced data; interactive visualizations.
