About John

Looking for a developer who can take your project from start to finish? I build complete web applications and AI solutions — from .NET backend and database to Angular frontend and deployment on the server — without needing a whole team.

How I can help you:

Web apps & websites — full-stack development with .NET / C# and Angular: fast, responsive, and maintainable.
AI integration — voice agents, chatbots, LLM connections (including Claude), and RAG knowledge bases on top of your existing system.
Automation — RPA bots, web scraping, and data connections that eliminate manual, repetitive work.
Maintenance & further development — taking over, stabilizing, and expanding existing codebases.
What sets me apart: I deliver the entire process myself — both the technology and the strategic thinking about its value — with over 6 years of experience in software development and automation (including RPA, data migrations, and HR software).

Typical assignments: a new web app from scratch, adding AI to an existing product, automating a process, or strengthening an ongoing project. Available for remote assignments — NL and international.
