About
Angel Mandujano
Started as a full-stack .NET developer in 2012, then took a research detour — a Master's with Distinction in AI/ML at CIC-IPN. Since 2017 the work has been data-intensive backend systems end to end: IoT data lakes and streaming at Innomius, ML infrastructure at Oracle, Web3 products at tokenproof, and financing systems at BlackRock today. The through-line: owning systems from design to production.
