Personal Projects
RepoTool (Work in Progress)
Command-line utility designed to parse, analyze and interact with code repositories
- Written in C# with EF Core (incl. Migrations) using SQLite
- Inference (per task) via provider-based or self-hosted large language models (LLMs)
- Language-agnostic parsing with own structured output (JSON Schema) data structure
- Languages can be configured with glob-based matchers
- Understands and leverages Git-based version control for indexing
- Argument parsing and command-line interface with LLM visualisation
- Extensible and user-controllable via templates
- Suitable for even subpar structured output support
Personal website

Dissertation Project
GitHub repository for my honours dissertation project dealing with retrieving accurate camera positions in the GPS datum, assuming they are of a popular landmark, given a dataset with a small subset of accurate GPS image tags.
- Semi-automated dataset gathering from Flickr to collect relevant image datasets.
- Implemented image filtering to deduplicate and remove blurry or low-resolution images, ensuring dataset quality.
- Extracted EXIF data from images and converted GPS data into a compatible format for easier pipeline ingest.
- Utilized OpenMVG for 3D reconstruction to accurately model landmarks.
- Enabled merging of models for localisation by reverse-engineering the model data format to enhance localisation capabilities.
- Performing validation and testing on reconstructed models to ensure accuracy and reliability.
