Co-founder and CTO of Solidroad (W25) and a second-time founder. Previously co-founded Monaru (S2019), where we helped individual creators earn $100k+ each by selling live classes online. Before that, I was as a product engineer at Intercom. I hold a BAI in Computer Engineering from Trinity College Dublin; my research focus was on dispute resolution mechanisms for Ethereum smart contracts.
