Summary
👤
Senior🎓
Top SchoolNik Gridinskiy is a Senior Software Engineer in San Francisco with 11 years of experience building high-throughput, production-grade systems across Scala, Java, and full-stack environments. He has led service rewrites and migrations—applying domain-driven design and continuous delivery—to reduce complexity and save infrastructure costs, and designed an in-house lightweight dependency injection model and productivity libraries to streamline microservice development. At Credit Karma he architected a data pipeline for credit monitoring alerts and cut ingestion latency for ML report pulls from 500 ms to 25 ms, while mentoring engineers up to higher-kinded types and functional programming. Earlier roles include scaling real-time bidding systems and creating a rare binary CQL3 connector for Cassandra, reflecting deep systems and protocol-level experience. Comfortable across distributed systems, data pipelines, and developer productivity, he brings a practical focus on measurable performance gains and team enablement. He has a background in computer science and applied mathematics and a playful, contrarian sense of humor—he “likes toast” and enjoys making complex things seem more complicated.
