Summary
👤
Senior🎓
Top SchoolAlexey Efimov is a senior backend engineer with over 19 years of professional experience and a 25+ year history in backend development, now based in Tallinn and currently building payments systems at Bolt using TypeScript. He has led infrastructure and SRE teams at Yandex, shipped large-scale video and browser backends, and ported complex media and CI tooling across Java, Kotlin and Python stacks. Comfortable from low-level C++ UI work to cloud-native fintech services, he favors pragmatic tooling (and "Bash at worst") while mentoring teams through operational challenges. A former university lecturer in queueing theory, he brings both formal systems thinking and hands-on implementation to reliability and performance problems. Notably, his career blends production-critical fintech and media systems with a knack for playful engineering metaphors—"antivibecoder" and honey badger armor—hinting at a pragmatic, resilient approach to software.
