Custom Digit Classifier

Machine Learning

CNN built from scratch in C++/CUDA with hand-written backprop, im2col, and GEMM kernels. 99%+ on MNIST at ~10% the throughput of an equivalent PyTorch/cuDNN model on T4 GPUs.

C++CUDA

GPT-2 from scratch

Machine Learning

124M-parameter decoder-only transformer with causal self-attention and learned positional encodings. Optimized for multi-GPU CUDA with minimized CPU-GPU sync — 11× speedup over the pre-optimized baseline.
