Back to original languageAbout Ivo
I have worked with startups, had my own startup, and therefore enjoy working in a passionate team. My experience lies in gathering requirements and intensive customer contact, elaborating these requirements well, and then writing efficient code to make it work. I naturally use the latest innovations in AI (Copilot in the IDE, OpenAI API in code), but only for the elaboration: I handle the architecture and the final quality control manually. This ensures we can move fast with a small team.
Unfortunately, we are now winding down this startup, and I am therefore simultaneously looking for a new challenge.
In terms of technology, I am proficient in React (NextJs, Native) and back-end development with Python (Django or FastAPI) and ExpressJS.
