About

I'm a versatile software engineer with experience in backend Java, frontend development, and AWS-based DevOps/SRE. I've built production features with Spring Boot, created internal tools in Angular & React, and worked across cloud infrastructure, automation, and monitoring.

I enjoy experimenting with JavaScript, real-time systems, and game development. I like solving problems across the stack and am not tied to a single specialty.
