Summary
Sushil Kumar is a Principal Engineer with 12 years of experience designing low-latency, high-throughput data platforms for marketing, advertising, and supply-chain domains. He blends deep big-data and ML expertise—Spark, Beam, Dataproc/Dataflow, Databricks/Delta Lake—with production systems skills in Golang, Kubernetes/EKS, and cloud-native tooling on GCP and AWS. At companies like Twilio, Twitter, Wayfair and dunnhumby he’s built data lakes ingesting hundreds of thousands of events per second, driven GDPR-compliant deletion flows, and cut costs and latencies through thoughtful architecture. He pairs hands-on implementation (from Spark ML pipelines and feature stores to microservices and Terraform infra) with systems thinking around on-call excellence and operational reliability. Notably, he has converted high-level designs into reusable platform components—such as a multi-tenant analytics platform and an in-house scheduler—that delivered measurable cost and performance wins. Outside core engineering he writes about technologies on Medium and shares code on GitHub, showing a sustained commitment to knowledge-sharing and practical craftsmanship.
