About

The person behind the code.

Nearly 20 years in software development, most of them as a software lead engineer. From designing system architectures to implementing robust test automation, from writing efficient low-level code to deploying scalable cloud solutions.

My approach combines technical rigor with creative problem-solving. I believe the best software comes from understanding both the engineering challenges and the human needs behind every project.

Currently focused on building AI-powered products and helping teams establish quality-first development practices.
