Senior🎓
Top SchoolSergey Voyteshonok is a pragmatic technology leader and CTO with 11 years of experience scaling engineering organizations across fintech, crypto, industrial digital and geospatial domains. He has repeatedly turned complex technical estates into reliable, cloud-native delivery machines — most recently leading a 30-engineer team to a Top-10 crypto wallet by downloads while cutting release cycles and embedding AI into developer workflows. Sergey drove a 5x reduction in critical incidents and cut incident response from an hour to under a minute by establishing SRE practices and advanced observability, and boosted unit test coverage from 20% to 60% through company-wide AI tooling. As a founder he delivered a profitable government GIS contract end-to-end, and earlier in his career he built GIS and web apps on .NET, PostGIS and modern JS stacks, contributing open-source mapping tools. Comfortable in multicultural, distributed teams and open to relocation, he combines hands-on engineering depth with strategic leadership in high-risk, high-scale environments.
