I’m Cantor, a backend and blockchain engineer focused on distributed systems, DeFi infrastructure, and the Sui ecosystem.
I work primarily in Rust and spend most of my time designing and operating production systems around transaction execution, blockchain indexing, sponsored transactions, authentication, routing, and protocol infrastructure.
At Aftermath Finance, I’ve worked on infrastructure and backend systems behind products including Dynamic Gas, afSUI, perpetuals, DCA, limit orders, and other parts of the protocol stack. My work has included transaction sponsorship, Sui transaction construction and execution, indexing pipelines, internal data services, API infrastructure, and production reliability.
A large part of my engineering work is concerned with systems that sit between on-chain protocols and real applications: translating blockchain state into usable data, constructing and executing transactions safely, handling failures and recovery, and making decentralized protocols usable without hiding their underlying constraints.
I also spend time researching protocol design and cryptographic mechanisms relevant to DeFi. Topics I write about include liquidation mechanisms, isolated lending markets, cryptographic accumulators, transaction sponsorship, distributed systems, and infrastructure design on Sui.
This blog is mostly a place for technical notes, research, and ideas that are too detailed for a social-media post and too unfinished for an academic paper.
You can find me as Cantor across most of my public technical work.
