Rockstar🎓
Top SchoolIlya Priven is a Senior Software Engineer with 13 years of experience building scalable, production-grade distributed systems, currently working from London and now at Wiz after multi-year engineering leadership at Lyft Bikes & Scooters. He specializes in backend systems in Python and Go on AWS (DynamoDB, SQS, S3) and Kubernetes, with hands-on experience spanning web (TypeScript/React) and mobile (Swift) stacks. At Lyft he helped run North America's largest bike-share networks, improving reliability, mentoring engineers, and partnering with infra teams to ship operable services at scale. A long-time open-source contributor, he has made substantive backend contributions to widely used Python projects like PynamoDB and mypy/typeshed, improving type safety and DynamoDB interoperability. His background includes low-level systems work—kernel USB components and cross-platform toolchains—giving him a rare blend of systems, tooling, and cloud-native service expertise. Colleagues describe him as a pragmatic engineer who pairs deep technical skill with a focus on running and operating resilient consumer services.
