01About

Founder of Wide Spectrum IT. Practical engineering, built to last.

I'm a software developer and founder of Wide Spectrum IT. I build reliable web applications and custom software solutions with TypeScript, Angular, and Node.js, with a strong focus on maintainability, performance, and clear architecture. I work remotely, wherever I can find peace and focused time.

My work is grounded in practical engineering: modern Angular patterns, clean project structure, environment strategy, versioning and release clarity, and disciplined development workflows. I am currently focused on AI and on applying it in ways that lead to concrete, production-ready software solutions.
