What I'm looking for

I’m looking for a role where I can own architecture and delivery for cloud-native fintech and real-time payments—building distributed, event-driven systems end-to-end, leading technical direction, and driving secure, scalable releases.

I’m a Software Architect and Senior Full-Stack Engineer with 10+ years of experience designing, building, and operating cloud-native platforms across fintech, digital payments, remittance infrastructure, SaaS, enterprise software, GIS, and media technology.

I co-founded ARG Software, where I combine architecture and hands-on engineering with stakeholder communication, delivery ownership, code review, CI/CD, and scalable product development for international clients. I own technical discovery, architecture, implementation, delivery planning, code review, CI/CD design, and release workflows, and I build full-stack applications and payment infrastructure using modern TypeScript, Node.js, .NET, React/Angular, databases, and cloud-native tooling.

My work in payments and financial inclusion focuses on interoperability and near real-time settlement concepts. I supported remittance infrastructure concepts within the Interledger Foundation ecosystem (People's Clearing House) and contribute to Mojaloop vNext, where I’ve worked on event-driven payment API components and operational tooling—achieving load-test performance around 1,000–2,000 requests per second, with ~200–300 ms lookup and quote workflows, and ~770 ms average ledger transfer processing.
