About Me

About Me

profile picture with laptop

My name is Sebastiaan

A Data Scientist & AI Student based in Haarlem

From a young age I've been curious about how things work, and that curiosity turned into a passion for solving problems with data. I'm currently studying Data Science & AI at Breda University, developing my skills in Python, machine learning, and data analysis.

Alongside my studies, I run SitesBySeb, a web development business, so I also know how to make things look good and work smoothly for real users.

Education & Skills

I'm building a strong foundation in data analysis, focusing on Python, statistics, data visualization, and extracting insights from data while studying Data Science & AI at Breda University. Before that, I spent a few years running a web development business, which taught me how to build practical solutions and understand the needs of users and businesses.

Work & Experience

Fire Safety Specialist

Part time | Schiphol

2023-Now

Ensuring fire safety at high-risk locations such as Schiphol. I monitor risks, inspect safety equipment, and respond to emergencies, developing strong attention to detail and reliability under pressure. I started delving deeper into sales to attract more clients.

Data Analyst, IKEA

Part time | At home

Nov-Dec 2024

Built a Power BI dashboard to detect fraud patterns in IKEA's data, covering data cleaning, analysis, and presenting insights. This project highlights my data analysis skills.

Web Developer

Part time | At home/University

2020-2024

During my studies at HBO University (InHolland) in Haarlem, I further developed my coding skills. I completed various online courses and also maintained the websites and programs of my clients.

During my BIP at SRH Heidelberg, I collaborated in an international team to develop an autonomous driving system using PiCars. The project focused on applying computer vision and AI techniques to enable lane following and traffic sign recognition for autonomous navigation.

Throughout the project, I gained practical experience with AI-based decision-making, computer vision, and robotics applications. In addition, the program included company visits to SAP and SAS, providing insights into how modern technologies are applied in industry. The BIP combined a virtual preparation week with an on-site week in Heidelberg.

Reinforcement learning controller benchmark

This block, I built an end-to-end robotics AI pipeline around the OT-2 simulator, from computer vision and coordinate transformation to motion control and evaluation. I mapped the robot’s safe workspace, implemented and tuned a 3-axis PID controller, and reached sub-millimeter positioning accuracy (0.245 mm final 3D error).

I also designed and trained a custom Gymnasium + Stable-Baselines3 reinforcement learning controller (PPO/SAC), then benchmarked it against PID to compare precision, stability, and adaptability.

The final integration combined U-Net root-tip detection with robot control for automated inoculation, and I documented both successful results and remaining transformation issues for the next iteration.

REBUP

REBUP Haarlem website home page

Stichting Rebup is a cultuurhuis in Haarlem: a place where young people can let their voice be heard, express their emotions and discover their own talents and strengths.

I built a multi-page website around their programme — a home page that introduces the foundation, an agenda for upcoming activities, pages for the team and the Rebup Krant, and a clear contact and FAQ section.

The design deliberately keeps the focus on their own photos and video, so visitors get a real feel for the space before they ever walk through the door.

Ambitiez helps young people earn well during their tussenjaar by matching them with hands-on work in the green and outdoor sector.

The site had to speak to two audiences at once: students looking for a well-paid gap-year job, and employers looking for motivated people. I structured it so both groups find their own route quickly, with everything pointing toward one clear action — signing up.

Bright colours and on-location photography carry the energy of the brand, while the layout stays calm and easy to scan on mobile.

I developed an AI project from the ground up, covering each phase of the CRISP-DM cycle. The goal? To predict wildfire severity using satellite imagery — showing how AI can play a powerful role in tackling real-world challenges.

Alongside building the model, I also created a business plan and user-friendly design, laying the groundwork for something that could be developed further into a real-world application.

IKEA dashboard: suspicious activity analysis
IKEA dashboard: conclusion and recommendations

For the IKEA project, I worked with data provided by IKEA to create a Power BI dashboard aimed at identifying patterns and uncovering potential fraud. The dashboard focused on analyzing employee activity to highlight suspicious behavior.

My goal was to detect anomalies and provide actionable recommendations to support IKEA in addressing these findings effectively.

For a rental house, I designed a website based on an existing design but added my own creative touch.

The client requested 5 pages, but I added an additional 3 pages myself to enhance my skills and make the client even happier.

The website has been very well-received, and I am very satisfied with the end result. It was a great opportunity to improve my design skills while having a satisfied customer at the same time.

Twitter course

I had a Twitter website created for my followers to explain how I have grown.

It was a great opportunity to experiment with new design techniques and expand my skills. I designed the website myself.

This website was a challenge to improve my skills and help others achieve their goals by sharing valuable content. It also helps me to create even better websites in the future.
