Top SchoolAlexander Kharitonov is a hands-on CTO and founder with over two decades of experience building high-performance, distributed systems and Big Data platforms, currently based in Boston. He combines deep expertise in Java/Kotlin and low-level networking with a practical focus on reliability, scalability, and delivering results quickly. Alexander has led engineering at Coin Metrics (VP of Engineering) and architected production-grade distributed databases, APIs, and real-time data pipelines used at institutional scale, contributing to a successful acquisition by Talos. He now drives AI and agent-oriented products across multiple startups, integrating AI with external knowledge and tools while avoiding reliance on external LLM APIs. Known for designing elegant, cost-efficient scaling strategies (including near-infinite storage approaches) and building uncommon pieces like in-house columnar stores and sequencers, he prefers simple, effective solutions to complex problems. His background blends research, full-stack implementation, and repeated founder experience, from hugely loaded chat servers to experimental mind‑reading tech.
