Things I built end to end

Kurt, an Offline-First AI Tutor

A fully local desktop assistant that transcribes lectures, answers questions grounded in your own documents, and compiles the result into typeset PDFs. No network required.

Tkinter has no MathJax, so multi-line equations are intercepted from the model's output and rendered through matplotlib's typesetting engine into transparent PNGs embedded inline: real mathematics in a desktop chat window, entirely offline.

F1 Telemetry Dashboard

Live and historical Formula 1 telemetry: speed, throttle, brake, RPM, gear, DRS, tyre strategy and a GPS track map, streaming from F1's official timing feed with no paid tier.

Drivers cross the line at different moments, so speed-against-time never lines up. Telemetry is interpolated onto a uniform five-metre distance grid, which is what makes two drivers genuinely comparable at the same braking point.

Image-to-LaTeX Handwriting OCR

A 2D-attention encoder-decoder that reads handwritten text and mathematical expressions and emits LaTeX autoregressively: ResNet-18 features into a four-layer Transformer decoder over a 1,007-token vocabulary.

A flattened feature map loses the two-dimensional layout that makes a fraction a fraction, so the encoder carries separate sinusoidal encodings for the X and Y axes. The decoder can tell what sits above the bar from what sits below it.

ViT Compression Trade-offs

Four Vision Transformer compression paradigms (token merging, threshold masking, post-training quantisation and entropy-based head pruning) mapped across a 24-combination sweep of the Pareto frontier.

Deleting tokens outright breaks the 2D spatial grid that hybrid convolutional models need, so token importance is proxied by L2 norm and low-importance embeddings are zeroed instead. The tensor keeps its shape and the downstream convolutions still work.

LaTeX Converter

The earlier image-to-LaTeX pipeline, carrying the dataset assembly, training loop and logging that the 2D-attention model above grew out of.

Hand-Gesture Drawing Tool

Draw in the air: real-time hand tracking turns fingertip position into geometric constructions on a live camera feed, with both hands working independently.

A pinch is not a distance threshold, because fingers approach at an angle. Detection combines distance and angle, and a One Euro filter then removes tremor without adding the lag a fixed-window average would.
