About

I am a senior software engineer and full-stack developer with more than 13 years of experience building scalable web, backend, and mobile applications. I enjoy turning business ideas into reliable products and have worked extensively with React, Next.js, Node.js, NestJS, TypeScript, WordPress, microservices, API integrations, and Kubernetes-based deployments.

I bring a practical, collaborative approach to engineering, with a strong focus on clean architecture, maintainable code, and quality delivery. Alongside hands-on development, I have led technical decisions, designed application architecture, mentored developers, estimated project risks, and supported infrastructure management across logistics and client-focused software projects.
