I design systems that can grow without turning into an archaeological site. That includes modular applications, microservices, integrations and technical decisions aligned with real business needs.

I build responsive and accessible interfaces with Angular, React, Vue and modern UI libraries. The goal is simple: applications should feel clear, fast and pleasant—not like internal software from 2004.

Java and Spring Boot are at the core of my backend work. I build secure APIs, business services, integrations and data layers designed for performance, stability and long-term growth.

I connect modern AI models with real applications and business workflows. From assistants and document processing to custom automation, I focus on useful solutions rather than adding AI stickers to ordinary features.

I take projects from an empty repository to a running production environment using Docker, Linux, CI/CD, Nginx, Traefik and practical automation. Fewer manual steps, fewer mysterious deployment rituals.

I help untangle difficult systems, select the right technologies and turn vague requirements into an actionable plan. Sometimes the best solution is sophisticated. Sometimes it is deleting half the unnecessary complexity.
