About Valerii

Technology leadership with depth, vision and hands-on execution.

Valerii Tsoi

Hands-on technology executive and software architect with 20+ years of experience building and modernizing complex products across enterprise AI, search and data platforms, fintech, capital markets and regulated B2B environments.

I combine executive ownership with a player-coach leadership style: setting technical direction, solving difficult architecture and production problems, mentoring senior engineers, and staying close to APIs, data flows, cloud infrastructure, observability and code-level decisions.

I care about clarity, resilient architecture, trustworthy delivery, strong teams and systems that keep working when the environment becomes difficult. My background spans software engineering, infrastructure, banking, consumer finance, capital markets, cloud transformation, cybersecurity and enterprise AI.
