Senior🎓
Top SchoolShril Kumar is a Senior Software Engineer with a decade of experience building large-scale backend and big data platforms, currently focused on data governance and privacy at Roku. He has designed and optimized systems that serve hundreds of millions of users—most notably real-time personalization and low-latency marketing funnels at Groupon—and delivered multi-million dollar cost savings through cloud migrations and storage re-architecture. At Roku he architected a GDPR Data Deletion Framework using cryptographic erasure and built a high-throughput PII scanning engine that blends regexes with a Qwen 2.5 model to cut licensing costs and vastly improve request throughput. Proficient in Java, Python, Scala and distributed systems like Spark, Kafka, Hive and Airflow, he also contributes to open-source data tooling—adding DataFrame features to Koalas to improve pandas-on-Spark usability. Based in Bengaluru and trained at IIT (ISM) Dhanbad, he combines hands-on engineering with strategic ownership, mentorship, and a habit of tackling problems he initially “doesn’t know how to” solve.
