Senior🎓
Top SchoolIlias Mentzelos is a results-driven technology leader and CTO with nine years of experience building and scaling backend systems and engineering teams across fintech and proptech. He has a strong track record of driving performance improvements—cutting P99 latency from seconds to milliseconds, reducing CI build times from 12 to 2 minutes, and speeding hiring by 35% through process changes. Hands-on in Python, Kotlin/Java, TypeScript and cloud-native tooling, he has led monolith decompositions, introduced microservices and new datastores (MongoDB, Timescale) and shipped features that materially increased subscriptions and revenue. Equally comfortable mentoring engineers as he is proposing architecture, Ilias has promoted multiple engineers into senior and tech lead roles while running cross-functional squads. Based in England, he combines pragmatic execution with an eye for operational efficiency and measurable business impact.
