Photographing a receipt and logging its warranty expiration date is genuinely simple CRUD with a file upload — one of the more approachable builds here.
Build it
Effort: an eveningRunning cost: $0/mo to start
Why CanICodeThis says Build it
Uploading a receipt photo and logging the purchase date, item, and warranty length is ordinary CRUD with file storage
Computing and displaying the warranty expiration date is simple date arithmetic
An email reminder before a warranty expires is one transactional-email call on a schedule
The parts that'll cause problems
OCR-extracting purchase details automatically from a photographed receipt needs an existing OCR API rather than manual entry
Organizing by room or category for a large household inventory adds real taxonomy work
Linking to a manufacturer's actual warranty terms (not just a date you guessed) would need real per-brand research

The build prompt
Build me a warranty tracker: upload a photo of a receipt, log the item, purchase date, and warranty length, and get an email reminder before it expires. SQLite behind a small API, single-user login. Skip OCR auto-extraction for v1 — manual entry alongside the photo is fine to start.
