Hi, I'm Willem, a computer science student at NYU Tandon School of Engineering with minors in Cybersecurity and Mathematics. I've worked across machine learning, high-performance computing, and full-stack development—from building AI research tools at NEC Labs to optimizing 160+ GPU operations at Codestream.ai. My technical interests span deep learning, data science, and systems optimization, with hands-on experience in Python, C++, and frameworks like PyTorch and TensorFlow. I've co-founded V3nd3tta Technologies, an e-commerce business, and currently lead AI development for a precision medicine project analyzing cancer T-cell growth dynamics. Originally from Berlin with dual US-German citizenship, I grew up between Germany and the Boston area. Outside of tech, I'm Vice President of NYU's Kendo Club, and I enjoy violin, photography, rock climbing, and building computers. I'm looking to work with teams pushing the boundaries of ML, autonomous systems, or high-performance computing.

May 2025 - Aug 2025; Princeton, NJ, USA
As a Machine Learning Intern at NEC Laboratories America, I developed an end-to-end AI-powered research intelligence tool that transformed how executives analyzed corporate data and competitive landscapes. Working with Python, TensorFlow, and PyTorch, I implemented deep learning models for natural language processing to extract actionable insights from technical papers and patents. My role involved applying advanced data science techniques—statistical analysis, feature engineering, and predictive modeling—to identify emerging market trends and forecast technology developments. By building machine learning-driven analytics systems, I enabled data-driven exploration of new markets and significantly enhanced corporate understanding of both internal R&D activity and the broader competitive landscape.
September 2024 - May 2025; Offices in Spain and the USA (Remote)
As Director of Mining Operations at Codestream.ai, I oversee and optimize high-performance GPU and CPU mining operations across hydro-powered facilities in Kentucky, Iceland, and Paraguay. I lead R&D initiatives in crypto mining, AI workloads, and blockchain innovations, ensuring scalable, energy-efficient operations. My role includes building strategic partnerships with hosting providers, optimizing hardware performance, and managing infrastructure growth to maximize profitability and uptime. By integrating emerging technologies in AI and blockchain, I help position Codestream.ai at the forefront of high-performance computing and decentralized infrastructure.
June 2022 - September 2024; Chicago, USA (Remote)
I led R&D initiatives to identify optimal GPU investments, focusing on power capacity and future scalability, notably ensuring all power was dam-generated.
I also spearheaded the transition from Metamask and ETH NFTs in favor of Lightning or email login, enhancing user experience. After implementing these new login systems, I integrated Stripe payment flow on both front-end and back-end, facilitating seamless transactions.
Finally, I represented Navier at key industry conferences in Miami and Amsterdam, amplifying brand visibility in the mining services arena.

At Klang, I worked on Seed: a Massive Multiplayer Online game at the Pre-Production phase.
I used unity to author and review new content for many new feature pitches, allowing for dynamic content addition and new features being usable.
I also gave gameplay loops depth by creating interpersonal activities between characters, material for business loops, and governance systems.
I Improved content generation flow by giving feedback and working on improvements and documentation to the custom Game Data Editor at the company, improving usability and efficiency for future game designers.

I started practicing kendo at NYU in fall 2023 as a freshman with zero experience. The sport caught my attention because improvement is tangible but never finished—you can always get better at fundamentals, footwork, timing, reading your opponent. Three years later, I'm 1 kyu and serve as Vice President of NYU's Kendo Club. I won the 2025 NYU kendo tournament in my division, which felt good, but honestly the more meaningful part has been getting better consistently over time and being part of a community that cares about the sport.
What I didn't expect when I started was how much the community and culture would matter. There's a formality and respect to practice that's different from other sports—you're learning technique but also etiquette, discipline, how to take feedback from senseis who've been practicing for decades. Competing in collegiate tournaments opened up a whole new network of students and senseis from other schools. You practice with people who approach kendo differently, learn from watching how other clubs train, and build connections across the collegiate kendo community. As VP, I handle communications and tournament logistics for 80+ active members, which has taught me how to coordinate events and keep a club running smoothly

I attended HoyaHacks 2025 to develop CiviMeter as a solution to improve urban mobility through AI. Over 24 hours, my partner Robert and I built the platform using TypeScript (React) for the frontend and Python (Flask) for the backend, integrating computer vision AI for parking violation detection. The project was recognized for its innovative use of Generative AI and seamless real-world application, winning two major hackathon awards.
Working with a group of 4, this was my final project for the EG 1004 course at NYU Tandon. The box was cut out of birch wood, designed in fusion 360, and controlled by an Arduino Uno coded in C++.
