First year of uni. Shipped a full-stack mobile + web app. Here's where it's at honestly.

Vaultly — personal document vault. Scan receipts, warranties, insurance, anything. OCR extracts merchant, date, and amount automatically. Searchable vault, expiry alerts, subscription detection.

iOS. Android. Web.

The stack: FastAPI + PostgreSQL + pgvector, Next.js, React Native. Self-hosted on a Mac Mini under my desk. Docker Compose, Cloudflare Tunnel, automated CI/CD. No external AI APIs — I own the whole pipeline.

Where it's actually at:

Private beta, handful of real users, but looking for people to test and give honest feedback.

Extraction is working well on prices and dates, merchant detection improving

Semantic search live with pgvector

Building a dataset labelling pipeline to fine-tune my own extraction model on real documents

The OCR is still in early development, I am looking to move onto a ML pipeline when I have time to train the model

The goal was always to own the full stack. No OpenAI dependency, no third-party OCR service, no shortcuts that I'll have to rip out later. Every layer is mine.

Pre-revenue. Early. But it exists, it works, and real people are using it.

getvaultly.uk if you want to look at it.

Happy to talk tech, stack decisions, or the solo build experience. What's everyone else running for self-hosted infrastructure?
