Hi, I'm Samuel.
I'm a physicist turned software engineer. I helped build Spiko as first employee and CTO. Now I focus on AI as engineering leverage: agents for operations, better tools, and faster small teams.
Building tokenized finance from day zero.
I joined Spiko's founders as the first employee and built the core platform behind regulated, tokenized cash-management products: customer-facing apps, operational workflows, and public-blockchain rails used by the business today. I also recruited and led a small, high-performing engineering team to scale it.
