Projects I've built and shipped.

Some I'm proud of, some I'd rewrite, some I forgot I built.

All projects

  • ExPLoRe

    Official PyTorch implementation of the ECCV 2026 ExPLoRe paper. Repurposes Soft-MoE dispatch weights as learned, per-patch loss coefficients for multi-objective masked image modeling — loss-coupling lets gradients flow through dispatch to the router for content-dependent specialization. ViT-Base + CLIP-B/16 teacher hits 80.6% linear probe and 85.3% finetune on ImageNet-1K.

  • MEDiC

    Official PyTorch implementation of MEDiC: Multi-objective Exploration of Distillation from CLIP. Combines token distillation, CLS alignment, and pixel reconstruction with Evolved Part Masking. Achieves 85.07% finetuning and 73.92% k-NN on ImageNet-1K.

  • Hevy → Garmin Sync

    Web tool that pulls strength workouts from Hevy and writes them into Garmin Connect with exercise names, sets, reps, weights, HR overlay, and calorie estimation. Solves a real gap in both apps' APIs. 36 stars, 109 forks — the most-forked project I have.
