Challenges

PROBLEM: Needed to work with location for proximity and filter out audience for a classified SOLUTION: Turns out mongodb has support for geoJSON

PROBLEM: Once the bids or audience of a classified grows it will become slower to filter them out. SOLUTION: Used extended reference pattern in schema design for classified

Short Comings

Backend

1. I used extended reference pattern in schema design but it has not been implemented properly in APIs.
2. A user can submit same bid multiple times, which can be a potential issue.
3. Get Classifieds will pagination when app scales

Frontend

1. Classifieds route and my Classifieds will need pagination on scale
2. Forms can be improved for UX

How it will scale

Initial Phase : A monolith and a db with proper indexes. Phase 1 : A Monolith with read replicas Phase 2 : Move to microservices the project structure is in accordance with that. Phase 3 : Maybe use caching / sharding
