I build scalable Java and Spring Boot microservices for reliable real-time billing systems.

At Amdocs, I build and maintain Spring Boot microservices across the Real-Time Billing platform, supporting roughly 35 services and REST APIs used by internal teams.

I implement reliable event-driven communication with Apache Kafka, including retries, failure handling, and DLQ paths. I also work with Couchbase and SQL databases to keep billing reads and writes performant, and investigate production API, Kafka, and data issues during L3/on-call rotations.

Previously, I built a Node.js payment API integrated with Mercado Pago, Android features in Java and Kotlin, and web applications using Java, JavaScript, HTML, and CSS. I also designed a programming language and compiler in C++.
