Senior Java Developer (Jul, 2018
–Present) at Zubrix Technologies
I am a Backend Engineer specializing in Java and Spring Boot, with extensive experience building scalable and production-ready backend systems. My expertise includes designing REST APIs, microservices architectures, asynchronous messaging systems using RabbitMQ, and distributed caching with Redis.
I have worked on high-traffic applications integrating with the WhatsApp Business Cloud API, building multi-client messaging platforms capable of handling large volumes of requests. My work focuses on reliability, scalability, and performance optimization using technologies such as Spring Boot, Spring Security, Hibernate, Redis, RabbitMQ, and Resilience4j.
In addition to backend development, I also have experience in DevOps and infrastructure management, including Docker-based deployments, CI/CD pipelines using Jenkins, monitoring with Prometheus and Grafana, and server virtualization using Proxmox. I regularly design systems that support asynchronous processing, fault tolerance, and distributed architectures.
As a mentor, I help developers learn real-world backend engineering practices, including Spring Boot application development, API design, microservices architecture, messaging systems, caching strategies, and production deployment. I enjoy helping developers understand complex backend systems and guiding them in building scalable, maintainable applications.
