Rockstar🎓
Top SchoolIlya Ozherelyev is a Senior Software Engineer with 11 years of experience building resilient, distributed infrastructure and orchestration systems, currently shaping foundational platform work at Databricks. His background spans high-scale roles at Uber—contributing to the Cadence workflow engine and a stateful orchestration platform—and earlier work on cloud services at Yandex and blockchain infrastructure at Insolar. Ilya is a pragmatic backend engineer fluent in Go and Python who focuses on API design, data serialization, and making long-running, stateful workflows reliable. Colleagues describe him as easygoing and collaborative; less obvious is his pattern of moving legacy systems to modern stacks (Perl to Go) while adding robust test coverage and protocol compatibility. Based in Aarhus, Denmark, he combines deep systems-level expertise with an appetite for new technical challenges.
