Alexander Donesky

Engineering manager & technical product strategist working in crypto

I build backend systems and developer-facing products for crypto. For the past five years at MetaMask I owned the roadmap and led delivery for the API platform powering dapp connectivity for 30M+ users, spanning EVM and non-EVM networks. I also author open standards across EIP, CAIP, and SIP, and work across product, engineering, and developer relations to keep technical roadmaps grounded in both engineering reality and where the ecosystem is heading.
