Freelancer profile translated to English.

Description

I help companies quickly and cleanly implement MVPs, software products, and integrations – from architecture to production. As a Senior Full-Stack Engineer with 7+ years of experience, I develop cloud-native applications, APIs, and platforms with a focus on Java, Go, React, Kubernetes, and cloud infrastructure. I work end-to-end and take on technical ownership in backend, frontend, and deployment. I am particularly well-suited for projects in product development, SaaS, data-driven applications, and integration platforms. My goal is pragmatic implementation with clear results, fast iteration, and sustainable technical decisions.
