PROFESSIONAL EXPERIENCE

Principal Software Engineer

Confidential

Responsibilities:

• Designed and developed ingestion framework which ingests and index 25,000 events per second on a commodity laptop.
• Architected and developed real-time index and search application using Lucene 7.0, Google Guice, REST and angular 6.0. Index is built incrementally as events are ingested from endpoints and is made available for search in real time.
• Implemented semantic search using Janusgraph, Cassandra and Elastic search.

Principal Software Engineer

Confidential

Responsibilities:

• Architected and lead development for analytics correlation engine using Drools' Complex Event Processing, which deals with the task of processing large volume of events from multiple streams (APData, APWeb, APEmail and endpoint server) with the goal of identifying and surfacing meaningful insight and anomalies within the events could, correlation engine is used by Summit as well as Proximo.
• Translate FIT rules into drools rules to be used in Proximo
• Wrote rules to be fired in real-time pipeline as APWeb, APData and APEmail events are ingested by Summit
• Designed and Developed Rules Engine to identify different personae (i.e. Exfiltrator, Saboteur, Stockpiler, Wanderer and Leaver) based on user behavior for Proximo
• Lead the effort to use graph based modeling and persisted storage as well as data model for Titan/JanusGraph databases for Proximo
• Wrote TinkerPop/Gremlin traversal queries to surface insights and anomalies in the events cloud
