SweetSpot

Inspiration

Idea came on a lengthy commute from DenHaag to Enschede while taking a nap and thinking of how stupid it is to missout on genuinely good finds because of how excitement over a new flashy thing either asks too much at the moment, or fades too fast to be reconsidered. Why buying something cool should at all feel in any way bad, unpleasant or turn debt?

What it does

Scan product with camera, find best prices instantly, then get notified when you can afford it when price drops. No overthinking, don't overpay for it. Just get it when you're both ready.

How we built it

Built it in 4, with a lot of pain and pleasure, downsizing and expanding, rethinking and enjoying. Looked for something that works, makes value, feels good and can be build upon further.

Final Creds:

Sweet Spot threshold: Bunq Api + Disposable income heuristics
Buy opportunity reasoning: Claude Sonnet
Image Recognition and Product querying: GoogleLens via SerpAPI
Frontend: React
Backend: Python, FastAPI, Postgres

Challenges we ran into

Maintaining clean quality code the closer we got to sunrise. Defining heuristics of what a good buy actually could be with no ML involved Messy API returns Confusion with bunq SDK Too little time to implement real time-series forecasting (that would be a game changer, why wont you add it on top?)
