Sandipan Kundu
Sandipan Kundu is a developer relations engineer and AI builder who spent five-plus years working across Ethereum-adjacent infrastructure teams, most recently as developer relations manager at Gnosis from 2024 to 2026. Before that he built and ran developer relations at Shardeum, first leading hackathon workshops and later rebuilding its documentation platform ahead of the network's testnet launch, after starting his web3 career as the second hire on Polygon's developer relations team. At Polygon he was lead organizer of Polygon BUIDL IT, a hackathon that drew more than 5,000 registrations and 300 projects and was, at the time, India's biggest web3 hackathon. His talk in the archive, a workshop on building with Circles, a social trust based currency, given with Maksym Fedorenko at ETHGlobal Buenos Aires, traces that same throughline of hands-on developer education applied to payments and stablecoin-adjacent protocol design.
