I am Sergio, a Washington State CPA, three-time AI hackathon award winner, and product builder specializing in public grants and government-funded R&D. I build at the boundary between accounting judgment and software execution:
- public-grant operations, post-award closeout, evidence review, and recovery workflows;
- agent infrastructure, source-bound execution, orchestration, and developer tools;
- open source, with upstream work in Ouroboros, K-Skill, ContractPlane, and Paperthin.
My recurring question is simple:
How do we turn professional rules into systems that remain inspectable, testable, and safe to act on?
