About

I'm a software engineer focused on high-performance, scalable back-end and full-stack applications. My core stack is Java, Kotlin, TypeScript, Python, Spring Boot, Node.js, PostgreSQL and DynamoDB.

I've spent most of my career on international remote teams in fast-paced, agile environments, with a strong focus on cloud infrastructure and DevOps automation. I care about clean architecture, strong ownership, and helping the people around me grow.
