Freelancer profile translated to English.

Description

I develop custom AI agents and SaaS solutions that automate repetitive business processes.

I've built about ten real-world projects: an automated prospecting agent (20 hours/month saved), a B2B SaaS platform with a conversational AI avatar, and several Next.js/Node.js applications in production.

I work fast, deliver working code, and am committed to the results.
