SOFTWARE DEVELOPER
I build things that bring
people, ideas and technology together.
NIMMO · JUNIOR DEVELOPER · PART-TIME
At NIMMO, I develop mobile apps in Flutter for passengers and drivers. My contributions include new features, improved accessibility, testing and releases to the App Store and Google Play. Together with the team, I also investigate and fix issues across the apps and backend.

NIMMO
The app for passengers and parents: find and book shared transport, view your tickets and follow your journey on the map.
My work ranges from journey search and booking to sign-in, child-related flows and accessibility — as well as test distribution and releases.

NIMMO DRIVER
A driver’s tool for running a trip, with an overview of the route, passengers and where to pick them up and drop them off.
I work on ongoing development, bug fixes, accessibility, backend integration, test distribution and releases to both app stores.

IN5320 · AUTUMN 2025 · GRADE A IN THE COURSE
A school inspection tool built with React and DHIS2. My main contribution was the analytics module: fetching, processing and visualising data on school resources.
Custom SVG charts make it easier to compare schools and track changes over time.

Games I want to understand, ideas I want to try and interests I want to explore further. Some things I build myself; others I contribute to with others.
From here, the thread follows three projects I spend my free time on.
OPEN BFME 1 & 2
I contribute to Open BFME, which reconstructs the game code of the Lord of the Rings games Battle for Middle-earth 1 and 2. Through reverse engineering, I analyse how the games work and recreate parts of their functionality in C++. My contributions have been merged into both projects, and I was invited to become a collaborator.

AIPODCAST
What if you could talk to a podcast? An AI prototype that lets you ask questions and hear exactly where in the recording the answer comes from. The prototype uses RAG and vector search in PostgreSQL with pgvector to retrieve relevant transcript excerpts as context for its answers.

CHESS
A local desktop chess analysis tool with Stockfish, Leela Chess Zero (Lc0) and support for other UCI engines. MultiPV displays several move variations at once. Local Syzygy tablebases provide outcomes and best moves for covered endgame positions. AI-based image recognition with a pretrained model lets you import board positions from images or a camera and review them before analysis.
