Senior🎓
Top SchoolRafał Malinowski is a Staff Software Engineer with 14 years of experience building and operating large-scale, fault-tolerant infrastructure and backend systems from Poland's West Pomeranian region. He has driven Kafka migrations to managed AWS MSK, introduced Aerospike and consistent-hashing sharding for MySQL tables with 500M+ rows, and designed rapid blue/green and canary deployment processes to minimize downtime. As a former technical team lead and recurring conference speaker and organizer, he blends hands-on engineering with team leadership, hiring, and process improvements. His background spans high-throughput ad-tech systems, search engines, and multi-datacenter deployments with automated scaling for billions of daily impressions.

Less obvious: he pairs deep systems work with developer ergonomics—introducing Vagrant, traceable SSH, and rapid rollback tooling to make complex platforms safer and faster to operate.
