About Sebastian Rehnquist

I'm a full-stack AI developer on Feeda aiOS, helping founders and teams turn ideas into working AI-native products. From frontend interfaces to backend infrastructure, I design applications that make AI accessible and usable in everyday workflows.
My specialty is the 0→1 journey: scoping, prototyping, and shipping MVP builds that scale. I work across React, Next.js, and Vue on the frontend, with Python, Node.js, FastAPI, and Express on the backend — deployed on AWS, GCP, Azure, or DigitalOcean. I bring it together with GPT-4/5, Anthropic Claude, and Feeda's APIs, copilots, and SDKs so your app ships with AI built in, not bolted on.
If you're launching a studio project, a startup product, or an app development venture, I'll help you go from concept to a working, scalable build.
