Products, infrastructure, and protocols.
I’m Samuel Dahunsi - a software engineer and mathematics graduate who builds production products, backend infrastructure, distributed systems, and blockchain protocols. I care about systems that are useful in production and precise about their guarantees.
At QuikDB, I’m a co-founder and software engineer working on backend systems, distributed compute infrastructure, deployment tooling, reliability, and platform architecture. Developer relations remains part of how I support adoption, not the centre of my engineering identity.
