Summary
👤
Senior🎓
Top SchoolCesar Pantoja is a CTO and co-founder with over a decade of experience building scalable fintech and crypto-enabled platforms, currently leading a cross-border payments startup and advising on AI readiness and responsible AI for SMEs and public-sector clients. He holds a PhD from Queen Mary University of London where he developed semantic and probabilistic approaches for forensic data, a background that informs his strengths in knowledge representation, systems architecture, and research-driven engineering. Cesar has a track record of founding and scaling products—from building a money-transfer intelligence platform and developer-led NFT projects to engineering high-throughput services at Coinbase after an acquisition—working across Java, JavaScript, C/C++, SQL/NoSQL and cloud-native tooling. A hands-on leader and educator, he blends practical full-stack delivery with technical writing and teaching experience, and advocates for inclusivity and gender equality within tech. Less obvious: his research-era expertise in ontologies and semantic graphs often surfaces in pragmatic data-model and integration designs for complex payment and AI systems.
