Luis Fleming is a hands-on CTO with over a decade of engineering leadership experience, currently solving the job market with AI at Talk Careers while also scaling products and teams at MindSpa.com. He has a track record of turning chaotic systems into reliable platforms—cutting error rates from ~50% to under 1%, boosting deployment frequency by 80% and improving user retention by 20%+. Comfortable across front-end and backend stacks (Flutter, React, TypeScript, GraphQL, AWS, MongoDB), he builds CI/CD, blameless post-mortems, and feature ownership cultures that let teams ship weekly. He progressed from senior engineer to COO-level ops, has led regulatory and acquisition-related engineering at a crypto exchange, and advised government on crypto policy. Based in Tallinn, Luis blends pragmatic API-driven engineering ("Give me an API to call, and I shall move the world") with a founder’s instinct for product and operational scalability.
