I asked Stijn to create a website which I could use to advertise my startup business I had to do for school to sell cookies. I had to make sure that it was user-friendly and easy to navigate. Stijn was very happy to help and teach me everything I needed to know to maintain the website if he wasn't available. I really appreciate Stijn.

Experience

Second Hackathon Victory
2024
I secured my second hackathon victory by developing a comprehensive security solution within a 48-hour timeframe. The challenge required creating a robust multi-factor authentication system integrated with a custom-built password and user data storage infrastructure. The solution needed to be fully functional across both web and native applications. Leveraging multiple programming languages including C++ and Python, I implemented a penetration-resistant system that met all security requirements. The flexibility to choose our tech stack allowed me to select the most efficient tools for each component of the system.
Customer Service AI Innovation
2023
I spearheaded the development of an AI-powered customer service platform that revolutionized a few companies' support operations. Using Python, TensorFlow, and natural language processing libraries like NLTK and spaCy, I built a system that automatically categorizes and routes customer inquiries. The solution also included a React-based dashboard for service agents and a Node.js backend with MongoDB for data storage. The implementation resulted in a 40% reduction in response times and improved customer satisfaction scores by 35%. The system now handles over 10,000 daily inquiries and has been adopted by multiple departments across the company.
First Hackathon Victory
2022
I won my first hackathon, competing against Delft University of Technology (TU Delft) in the 'IAmMirte' challenge. The task was to develop a webshop and remote control system for their robotics department, which I successfully completed within a 4-day timeframe. Using a modern tech stack that included Vue.js, React, and React Native, I built a responsive and user-friendly solution. These frameworks, combined with various supporting libraries, enabled me to create a robust system that met all requirements. Additionally, I collaborated with the team that ultimately placed second, helping them create a dashboard to measure electricity consumption across different neighborhoods.
