What I'm looking for

I seek roles where I can deliver end-to-end systems, own production infrastructure, work with Go and cloud-native stacks, and join teams valuing high reliability and strong testing.

I am a fullstack software engineer with 5+ years delivering scalable backend services, modern React and Next.js frontends, and production cloud infrastructure across distributed teams. I have deep expertise in TypeScript and Node.js, strong Java and Spring Boot experience, and a proven record building wallet and payment systems that process hundreds of thousands of transactions monthly with high reliability.

I design and operate containerised workloads on AWS using Kubernetes, Helm, and Terraform to achieve high uptime and zero-downtime rollouts, and I champion rigorous testing and observability standards that reduce bugs and speed incident resolution. I am actively learning Go and motivated to contribute in Go-first environments while continuing to drive end-to-end delivery from code to cloud.
