“I collaborated with Felix on a project for DezentralizedFinance.com to create a scalable logo map SaaS tool. Felix was professional, timely, and efficient. He excelled in communication, adapting to my vision of integrating a prototype with Google Sheets. With his expertise, especially in image rendering with Vercel OG Image, he closely matched my expectations, needing only slight style adjustments. What stood out was Felix's understanding of my workflow and needs. The prototype's value for money is impressive, and I look forward to future projects with him. I highly recommend Felix for his exceptional work and client-focused approach, solidifying his freelancing reputation.”
