Rockstar🎓
Top SchoolDenis Otkidach is a seasoned Python developer with 15 years of experience building and modernizing backend systems, currently driving production services at Exness from Limassol, Cyprus. He specializes in asyncio-based architectures, microservices (gRPC, Kafka), and database-heavy backoffice systems, having led technical efforts at ICONIC.VC and tackled complex legacy refactors at Rutube. A prolific open-source contributor, Denis has contributed to high-profile projects such as aiokafka and aiohttp, helping upgrade Python support and modernize compatibility layers. He pairs deep systems-level debugging and performance tuning with pragmatic engineering — for example, authoring a coroutine-based ClickHouse driver and migrating long-standing codebases to contemporary async patterns. With an academic background in chemistry, he brings analytical rigor and a habit of reverse-engineering undocumented systems to deliver resilient, well-tested services.
