Who I Am
About Me
Building technology solutions that make a real impact
My Approach
I build solutions that are technically robust and aligned with real business goals and user needs. My experience spans startups to large organizations, including a role as an Integration Architect for Government, where I designed enterprise-grade systems using Apache Kafka, Schema Registry, Spring Boot, and Kubernetes on Azure Arc (AKS) with Helm Charts.
I enjoy exploring new technologies, continuous learning, and mentoring teams. When I’m not designing distributed systems, I contribute to open-source projects or lead technical workshops, such as React training sessions. Recently, I’ve also started exploring Vue and Nuxt — in fact, this website is built with Nuxt.
