What I'm looking for

I’m looking to build secure, production-grade systems—especially payments, integrations, and AI-driven fraud detection—where I can translate requirements into microservices, own releases from dev to go-live, and collaborate closely with product owners and stakeholders.

I’m a Full Stack Developer and Implementation Engineer with 10+ years of experience delivering end-to-end payment and banking integrations, from analysis to go-live. I’ve worked with major banks in the Philippines and New Zealand, focusing on high-impact reliability work like HSM migrations, protocol translation between ISO 8583 and REST, and AI-driven fraud detection routing.

My strength is translating complex requirements into production-ready solutions across web and mobile. I’ve built and deployed microservices like a CBS API Gateway protocol translator, led onsite workshops to define scope and requirements, and supported releases with thorough development and testing practices—while also building compliance- and security-focused frameworks (e.g., encryption, RBAC, CSRF/CORS controls) for real business systems.
