What I'm looking for

I'm looking for a fast-moving product environment where I can own technical decisions, build reliable distributed and payment systems, lead teams, and work cross-functionally on high-impact infrastructure and applied AI products.

At Rivalry, I led payments and cashier engineering for an online sportsbook and casino platform, designing payment processing systems handling thousands of daily transactions. I built a unified PaymentIQ integration, direct and crypto payment-provider integrations, routing rules, fraud controls, back-office tooling, and responsive deposit and withdrawal experiences.

I've also co-founded SnapX, an AI-powered automated bookkeeping SaaS, where I took technical development from concept to production and led a cross-functional development and QA team. As CTO at Sécurité XGuard and Lead Web Developer at FlightHub, I set technical direction, built internal and customer-facing platforms, reviewed code, and mentored developers.

I'm currently building PayFlow, a production-deployed distributed event-driven platform exploring saga workflows, idempotency, reconciliation, observability, and agentic AI for payment operations.
