Summary
👤
Senior🎓
Top SchoolSergey Kozlov is a Staff Software Engineer based in Dubai with over a decade of hands-on experience building high-load backend systems using Python/Django and Go. He has led teams and architected distributed services at companies from startups to large engineering groups, including roles at Careem, Yandex’s self-driving cars team, and as CTO/co-founder of a high-throughput content platform. His expertise spans SQL and NoSQL databases (PostgreSQL, Cassandra), event-driven systems (Kafka, Debezium), and cloud delivery at scale—he built a system serving tens of thousands of views per second using Cloudflare and S3. Known for raising engineering standards (introducing code review, testing, and reliable CI/CD) and mentoring teams, Sergey blends deep technical craft with operational reliability and product-focused thinking. A not-obvious strength is his cross-domain fluency: from geo services for autonomous vehicles to privacy-sensitive monetization platforms, he thrives on solving complex, high-throughput problems.
