If you believe modern AI tools fundamentally change how fast products can be built — this role is for you.
I’m building a modern, user-friendly SaaS application focused on sales, inventory management, and business controlling — enhanced with an integrated AI assistant and Amazon/Shopify integrations for the MVP.
The prototype is already developed, and now we’ll move into full implementation and launch.
This is not a corporate role — it’s a hands-on builder position. You’ll work directly with me in a small, focused setup — with AI acting as an additional team member to accelerate development.
💡 What makes this exciting
You’ll co-build a real SaaS product from prototype to go-live
We’ll work with AI as a true team member (e.g. Cursor and/or Claude, ChatGPT)
Fast execution: target launch in 4–5 months
You’ll have direct impact on product, architecture, and features
Bonus for successful go-live
If you enjoy building fast and using the newest tools — this is for you.
🛠️ Tech Stack
We’ll use a modern, AI-friendly stack:
Frontend
React
Next.js
Tailwind CSS
shadcn/ui
Backend / Database
Supabase (PostgreSQL, Auth, Storage)
Hosting
Vercel (frontend)
Supabase (backend)
AI Integration
OpenAI API / Claude API (for in-app AI assistant)
Development Tools
GitHub
Cursor Pro and/or Claude (AI coding assistant)
ChatGPT (product & architecture support)
You don’t need to know every part of the stack — the ability to learn quickly, use AI effectively, and build pragmatically is more important.
🤖 What you’ll build
Core product features (sales, inventory, controlling logic)
Clean, intuitive UI components
Backend logic and database structure
AI-powered command interface (e.g. user inputs → system actions)
End-to-end product improvements toward launch
📍 Setup & Conditions
Location: On-site in Marienthal / Wandsbek
(5 minutes from Wandsbek Markt)
Small, focused working setup (home office environment)
Days: Mondays & Fridays (optional switch one day to Saturday, TBD)
Hours: 10 hours/week
Type: Minijob
Start: As soon as possible
🎯 Requirements
Master’s student in Computer Science or related field
Experience with React / Next.js or similar frameworks
Understanding of APIs, databases, and backend
Ability to build features end-to-end (frontend + backend integration), or the willingness to quickly grow into it
Fast, pragmatic, and hands-on working style
Ability to work independently and take ownership of tasks
Comfortable around dogs (there’s a friendly Golden Retriever around)
🚀 How we'll work
We move fast. We build in small iterations. We prioritize working solutions over perfection. We use AI tools heavily to accelerate development.
The goal is simple: Ship a working product in a few months.
The focus is on translating the existing prototype into a working product efficiently — without over-engineering or unnecessary complexity.
