December 2025Won the $10,000 Unsloth Prize · Google Gemma 3n Impact Challenge
Dream Assistant
A voice assistant that understands atypical speech, and never sends audio off the phone.
ResultAfter fine-tuning Gemma 3n with Unsloth on the cleaned, augmented audio, the model reached a 6.3% word error rate on atypical speech.
Problem & approach
- Problem
- Voice assistants fail people with speech impairments, and sending their recordings to the cloud is a privacy risk.
- Approach
- Collected about 200 recordings of everyday phrases from a person with a speech impairment, then trimmed silence, normalized volume and augmented each clip with noise and speed changes to make the model robust. Fine-tuned Google Gemma 3n with Unsloth so it runs on the phone, and built the Android app and its UI end to end.

Predicting drug potency with graph neural networks
Can a neural network read a molecule’s structure and predict how potent it will be as a drug?
ResultThe graph networks reached 70–74% classification accuracy, while a classical QSAR baseline reached 83%, a useful lesson in when deep graph models are, and are not, worth it.
Problem & approach
- Problem
- Testing drug candidates in the lab is slow and expensive. Predicting potency from structure narrows the search before anything is synthesized.
- Approach
- Our team of five turned 529 TRPM8 compounds from ChEMBL into molecular graphs with RDKit and compared five graph network architectures for classification and regression. I built and tuned the graph convolutional network (GCN).

Predicting loan default
Who will default on a loan? A model trained on 1.5 million real applications that has to stay reliable over time.
ResultThe best model, LightGBM, reached an AUC of 0.778 on held-out test data (0.782 validation, 0.792 training), so it generalizes with little overfitting.
Problem & approach
- Problem
- Lenders need to estimate default risk before approving a loan, and a model is only useful if it keeps working as their clients change. Built on Kaggle’s Home Credit – Credit Risk Model Stability challenge.
- Approach
- Working with one teammate, I cleaned and encoded Home Credit Group’s dataset, handled missing values, and engineered weighted days-past-due features that improved every model. Compared LightGBM, XGBoost and multilayer perceptrons.

Meow by Meow
What is your cat trying to tell you?
ResultAugmentation significantly improved the convolutional network, which reached over 90% accuracy.
Problem & approach
- Problem
- Classify a cat’s meow as comfortable, uncomfortable or hungry from a short audio recording.
- Approach
- In a team of five, we converted recordings to mel spectrograms. I proposed and implemented the data augmentation (time shifts, stretching, frequency masking) and built the convolutional network with a teammate.
