Built for small business owners who track income and expenses via mobile money but struggle with manual record-keeping. It reads M-Pesa message exports, categorizes transactions (sent, received, pay bill, buy goods), and outputs CSV/JSON reports ready for bookkeeping.

One script, one run, and your server meets baseline security standards. Ideal for solo devs and small teams spinning up VPS instances on DigitalOcean, Hetzner, or AWS.

Three open-source PRs (GitHub #29, #34, and a HuggingFace Hub PR) fixing device compatibility bugs in Baidu's large-scale OCR model. The core issues were hardcoded .cuda() calls that crashed the model on Apple Silicon (MPS) and CPU environments, plus a masked_scatter_ broadcast shape error that broke inference on non-CUDA hardware. The fixes make the model fully device-agnostic it now runs on whatever hardware is available without code changes
