About
$ building reliable APIs · infra · automation
I specialize in payment rails, Web3 frontends, and AI orchestration systems that survive production — Pay.Kobbex, DEX Kobbex, and Changetext.
Ten years across backends, DevOps, and platform engineering. I design ledger-friendly state machines, idempotent webhooks, and failure paths that support teams can actually use.
I mentor senior engineers, run architecture reviews, and prefer boring technology that keeps money and messages moving.
Available for principal/staff backend engagements and Web3 platform architecture.
Ship systems that operators can trust at 3am — explicit states, retries, and observability baked into the first version.
