Description

Hi! I'm Krzysztof, an experienced Full-Stack Developer & AI Specialist with 13 years of experience as a freelancer.

I help companies quickly build and improve web applications, dashboards, automations, and AI tools (especially with Claude). Whether it's a new MVP, a custom webshop, chatbot, or internal tool – I deliver clean, well-functioning solutions in a short time.

What sets me apart:

• Fast realization thanks to smart use of AI (up to 50-70% faster)

• Clear communication in Dutch, English, and Polish

• Full responsibility from analysis to delivery

• Experience with e-commerce, production, finance, and marketing agencies

Currently available for new assignments in Belgium and remote.

Feel free to let me know what you need – I usually respond within a few hours.
