Rockstar🎓
Top SchoolAlexander Petrosyan is a physicist-turned-software engineer with 10 years of experience building distributed systems and applying Bayesian inference to real-world problems. Based in Yerevan, he has led performance and research efforts at Eclipse Labs and Soramitsu and contributed backend improvements to the enterprise-grade Hyperledger Iroha ledger, focusing on logging and observability. His work spans blockchain architecture, dependently-typed language research, and performance engineering, and he has run a consulting firm negotiating technical partnerships across the ecosystem. Trained at the University of Cambridge (MS, Physics, 1st Class Hons.), he blends rigorous mathematical reasoning with pragmatic system design to tackle hard problems like the Hubble Tension using gauge-theory approaches. Colleagues know him for shipping durable infrastructure improvements and for an unusual combination of forensic fieldwork and trumpet training early in life, which reflects a habit of meticulous, cross-disciplinary thinking.
