Summary
👤
Senior🎓
Top SchoolDima Korolev is a founding engineer and systems architect with 12+ years building high-performance, data-heavy systems in C++ and cloud environments, currently spearheading a stealth startup and hosting the System Design Meetup. He specializes in event sourcing, CQRS, and total-order broadcast as pragmatic synchronization primitives, and has a track record of squeezing 10K+ HTTP QPS from a single core and zero-downtime data authority flips. Dima combines deep distributed-infrastructure expertise from companies like Miro, PokerStars, and Current with earlier ML/NLP research—co-authoring multiple patents—and practical SRE and OLTP experience at Google and Microsoft. He is an advocate for durable, test-covered architectures (Current boasts 90%+ test coverage) and a hands-on maintainer who still codes and benchmarks critical paths. Beyond engineering, he runs a popular system-design community (YouTube and meetup), mentors interview candidates, and blends technical rigor with long-term team culture as a hiring and retention principle.
