Freelance API Integration Developer - Patrick Verbeeten
Freelance API Integration Developer

Hi, I’m Patrick — a senior software architect and developer with over 25 years of experience, specializing in **.NET, Azure, TypeScript, and more**. I help developers understand how to **avoid problems** before they arise, with a focus on practical, sustainable solutions built on **code quality**, maintainability, and performance at scale. My work often involves improving architecture, introducing automated testing, CI/CD, addressing performance issues, and guiding developers toward more effective practices. I don’t just fix problems — I **teach you how to avoid them**, through a deep understanding of patterns, standards, and how to apply them in real-world code. Whether it’s untangling legacy code, improving deployment pipelines, or introducing better patterns, I help you understand the _why_ behind each change. And when you're facing an urgent technical challenge, I can step in and resolve it quickly and effectively. When it comes to code reviews, I take a different approach — not as a checklist of faults, but as a **conversation about quality and maintainability**. As my projects show, I don’t limit myself to one stack. I specialize in delivering **quick, creative solutions** to complex problems, then shaping them into solid, scalable foundations.
