What I'm looking for

Looking for a Senior Backend Engineer role (remote) where I can work with Java, Go, or Kotlin on scalable, high-throughput microservices. Open to fintech, e-commerce, or other product-driven companies with a solid engineering culture and room to grow into more senior/lead responsibilities.

I'm a Senior Backend Developer with over 4 years of experience building high-throughput, cloud-native systems in Java, Go, and Kotlin. My work has centered on taking complex, legacy architectures — monoliths and SOA systems — and transforming them into scalable microservices on Kubernetes, without losing sight of the operational realities that keep systems reliable in production.
