At Amdocs, I build and maintain Java Spring Boot microservices and REST APIs for global telecom clients including AT&T, M1, and INWI, processing more than 1 million daily data payloads.

I've built transformation pipelines that parse, normalize, and validate JSON, XML, and CSV data into standardized models with under 150ms processing latency and zero data loss. I also containerize services with Docker Compose, deploy them to Kubernetes through CI/CD workflows, and support 99.95% uptime with Grafana monitoring and structured logging.

My projects focus on distributed-system reliability: a multi-tenant rate limiter and API gateway using Spring WebFlux, Redis, Kafka, Resilience4j, and Docker, plus an event-sourced financial ledger using CQRS, PostgreSQL, Kafka, Debezium CDC, and the Transactional Outbox pattern.

I also use Cursor AI and Model Context Protocol to accelerate unit-test creation and technical documentation, and built a low-latency C++ and OpenCV ball-tracking system.
