I build secure systems that move money and data safely, and I believe the future of the internet depends on it.
- BirdyFoot Systems – consulting and building secure infrastructure for high-velocity teams
- TwigBush – open-source GNAP (Grant Negotiation and Authorization Protocol) engine built in Go
→ A new foundation for delegated trust, and secure AI transactions
- Designing authorization protocols for the AI era (key-bound, auditable, dynamic)
- Making secure payment flows programmable
- Bridging open-source and real-world production systems
- Helping teams go from chaotic → secure, observable, fast
- Ex-Mastercard, Amazon, Twitter consultant
- Now designing the secure dynamic infra layer under AI agents and fintech platforms

“If Clint Eastwood built open-source authorization, it’d look like TwigBush: tough, secure, and ready for the wild west of agentic transactions.”
| Project | Description | Tech |
|---|---|---|
| 🪶 TwigBush | GNAP Authorization Server & CLI (Go + chi + Cobra) | Go, OpenFGA, SSE |
| 💳 BirdyFoot Payments | Secure Agentic Transaction Layer for Trust | |
| 🧭 Infra Audits | Security posture assessments and Okta implementations for firms | AWS, Azure, GCP Terraform |
If you’re building secure agents, payments infrastructure, next generation systems or authorization systems, I’d love to talk.
