Full-Stack Developer & Freelancer

Hi, I'm
Krzysztof Kocot

I build modern web and mobile applications using AI-powered development workflow. Clean code, excellent UX, faster delivery. Working remotely from Katowice, delivering solutions for clients worldwide.

Passion for creating digital solutions

I'm a Full-Stack Developer with over 3 years of commercial experience. I independently design and build complete web and mobile applications — from database to UI.

AI is part of my daily workflow — projects ship faster and cost less. The results: a backend powering 8 applications, an open-source project with 50+ contributors.

You work with one person from idea to launch. After deployment I stay on board — maintenance and growth included.

Consultation

We discuss goals, scope, and budget. I recommend optimal technical solutions.

I prepare wireframes and design. You approve the direction before development starts.

Development

I build the application, sharing progress regularly. Testing and optimization included.

Support

After launch, I provide maintenance, updates, and feature development.

How I work

How we'll work together — from first call to launch day. Clear steps, regular updates, no guesswork.

What I stand for

  • Regular demos — preview before each milestone ends
  • Fixed scope — agreed deliverables, no mid-project surprises
  • Bug-fix warranty — post-deploy fixes included
  • Direct communication — no middlemen, you talk and write directly to me
