What I'm looking for

I’m looking for a team where I can architect secure, cloud-native microservices and event-driven systems—shipping measurable performance, reliability, and developer-friendly infrastructure while partnering across distributed domains.

I’m a results-driven Senior Software Engineer with over 10 years across the Software Development Life Cycle (SDLC), focused on architecting and deploying scalable, cloud-native applications. I specialize in Distributed Systems, Microservices Architecture, and Infrastructure as Code (IaC), and I’ve built real-time, high-volume systems with strong observability and security.

Most recently, I architect foundational PISP and third-party microservices/SDKs for the Mojaloop open-source ecosystem, improving latency and throughput through performance benchmarking and ledger optimizations. I’ve also engineered event-driven monitoring and reconciliation capabilities, streamlined API contract consistency with reusable OA3 type definitions, and built secure Identity Lookup Services using Node.js, Kafka, and Kubernetes—ensuring robust, containerized deployments for distributed financial entities.
