Behind the Code
I’m a backend-focused Software Engineer with hands-on experience in building real-time data pipelines, distributed systems, and scalable cloud-native applications. I enjoy solving technical challenges through clean architecture, efficient code, and thoughtful design.
Skills
As a backend-focused Software Engineer, I work with a modern stack built for performance, reliability, and scalability. From building APIs in Go with gRPC and Protocol Buffers to deploying resilient systems using Kubernetes and Docker, I specialize in developing distributed systems, observability pipelines, and cloud-native microservices. I thrive in environments where engineering excellence and clean architecture meet real-world impact.
