Hi, I am Andy! I’m a product manager with an M.Sc. in Computer Science from RWTH Aachen. I figure out what to build, then design and ship intuitive, user-centered products.

amber is an enterprise AI platform connecting company knowledge through AI search, chat, and agents, so users get the right information at the right time.

I own product strategy and delivery end to end with engineering, turning feedback from users, sales, and customer success into shipped features.

WebWriter helps educators create interactive worksheets and export them as HTML. I joined the team for my master’s thesis, working on a way for teachers to create adaptive lessons that follow different paths without having to write any code.

I designed and built a branching editor in TypeScript and Lit, then put it in the hands of five educators for a task-based study. Their feedback helped me identify what worked, where they got stuck, and what the team should improve next.

After my thesis, the team invited me back to design and develop an interactive-video widget, giving educators another way to bring their lessons to life.

An iOS sewing coach: sew the line, snap a photo, get feedback on technique. I was a software developer on it, working in Swift, SwiftUI, and OpenCV, and helped shape the look and the UX flow, with 10 sewing instructors.

ARPen is an AR CAD tool on iPhone. You take it to something in the real world, a broken pipe you need a part for, and sketch the first 3D model in place. The export keeps real-world centimeter dimensions, so the piece already fits the thing you were looking at.

For my bachelor’s thesis I added three features: new ways to scale and rotate in mid-air, and an undo/redo manager.

Finding your next game shouldn’t mean asking the coach to resend a PDF buried in the team’s WhatsApp chat. As a basketball player, I wanted an easier way to follow our season and understand what was happening across the local leagues.

So I built AachenBasketball.de, using official league data from the TeamSL API of the Deutscher Basketball Bund (DBB). It’s one place to find local clubs, explore their leagues, and check schedules, scores, and standings. NBA-style playoff brackets make it easier to see how the postseason works and who could face whom next.

It’s a personal project built around something I care about: making local basketball easier to follow for teammates, fans, and anyone looking for a club to join.
