I am a veteran Sales Engineer with a deep background in ISP Infrastructure (Layer 2/3) now specializing in the Payments, Fraud, and Compliance sector.
In my previous life, I mastered the "pipes" of the internet. Now, I’m mastering the value that flows through them. I bring a unique perspective to fintech: I don't just see a payment_intent API call; I understand the network handshake and the millisecond-latency requirements that separate a "Succeeded" transaction from a "Timed Out" loss of revenue.
Check out my latest technical documentation in my Payments & Fraud API Labs repository:
- 🛡️ PCI-DSS v4.0 & Compliance: Strategies for Merchant Scope Reduction (SAQ-D to SAQ-A).
- 🎓 Fraud & Dispute Masterclass: Certification in 3DS 2.0, Liability Shifts, and Representment.
- 🎭 Presales Methodology: Frameworks for Value-Based Discovery and Demo Excellence.
- Payments: Stripe (Connect, Billing, Radar), API Orchestration, Webhooks.
- Security & Risk: PCI-DSS v4.0, 3D Secure 2.0, Tokenization, and Fraud Mitigation.
- Tools: Postman (Collection Architecture), JSON/RESTful API Design, Git/GitHub.
- Background: Layer 2/3 Networking, High-Availability Routing, Infrastructure Security.
Most payment experts stop at the API layer. I go deeper:
- Network Reliability: I understand the routing logic that ensures high-availability for mission-critical gateways.
- Security Foundations: My networking background means I treat tokenization with "Zero Trust" principles.
- Strategic Discovery: I don't just demo features; I solve business friction and reduce compliance overhead.
