A bit about me

Meet

Welcome to my magical world of tech! With 7+ years of experience, I'm an entrepreneur and full-stack developer who loves tackling challenges, won’t back down, and always finds a way to create extraordinary solutions.

Daniel Rehberg - Computer Science Student
Let's Collaborate! πŸš€

Currently studying Computer Science while working as a student at Sovendus and building my own e-commerce business. I’ve contributed to projects like the developer-hub.sovendus.com, developed my own online shop, co-built a QA browser extension, and launched many other projects to deepen my expertise in computer science and brand building.

Exploring the world of AI through my bachelor thesis, I’m developing an AI-powered chatbot for companies that answers technical questions using documentation. I take on programming challenges head-on - from building my own headless Shopify shop to diving into Shopify app development. Alongside my studies, I run an Amazon business, build my own brand, and develop products from scratch - constantly learning, innovating, and pushing boundaries.

Join me on this journey of innovation - where technology, creativity, and entrepreneurship come together to shape the future. Let’s shape the future with solutions that inspire!

Project Showcase

Magical Creations

A showcase of projects that highlight my expertise in tech, AI, and e-commerce - delivering innovative and impactful results.

AI-Powered Chatbot for Technical Support

Bachelor thesis project: development of an internal AI-powered chatbot for technical support and account management teams. The system retrieves information from public documentation and code snippets using a Retrieval-Augmented Generation (RAG) pipeline and provides fast, accurate answers to integration and technical questions. In case of uncertainty, the chatbot clearly indicates it and offers a fallback to ticket or mail creation.

Information terminal application for the humanoid robot Pepper

Project work in the 6th semester in cooperation with the city of Furtwangen, HFU and CGI. We developed an infoterminal application for the humanoid robot Pepper, designed to provide visitors of the town hall with information and services. Pepper supported users interactively through speech, animations, and person recognition.

Automated Waste Separation using a Robotic Arm

Project work in the 4th semester: development of an automated waste sorting system using a Fruitcore Horst 600 robotic arm. The system detects and classifies plastic and metal bottle caps with OpenCV and the Canny algorithm, then sorts them using a custom-built gripper. Optimizations in lighting and the gripper design significantly improved accuracy and efficiency.

  • β€’Automated the entire product testing process via Telegram
  • β€’Integrated MariaDB for reliable storage of tester data and feedback
Word Clock

Final project at the Feintechnikschule: design, soldering and programming of a fully functional word clock built into a picture frame. The clock displays the time in words using an LED matrix controlled by an Arduino Nano, supported by a Real-Time-Clock and DCF77 module. A light sensor automatically adjusts LED brightness and the color can be switched via a toggle button.
