As a backend developer, I specialize in building robust and scalable systems. My experience includes designing database schemas, architecting ERP applications, and deploying high-availability infrastructure. I have a passion for creating self-managed observability stacks with tools like Grafana, Prometheus, and Loki to ensure system health and performance.
I am currently preparing for the Azure and AWS DevOps and Developer Associate exams, as well as the CKS and CKAD certifications to deepen my expertise in cloud-native technologies. I thrive on tackling complex challenges and am always eager to explore new technologies that drive efficiency and resilience.
When I'm not coding, I enjoy collecting books, catching up on my favorite TV series, and hunting for the best coffee in town.
