Isomorphic Kotlin
summary
Shows a lightweight backend built with Ratpack + Kotlin that ingests messy fuel-economy CSVs from fueleconomy.gov, maps them to Kotlin data classes, stores documents in MongoDB (mLab), and exposes REST endpoints for paging, get-by-ID or get-by-make. Routing handles method verbs and assigned ports for Heroku; deployment is a git push. Cold queries on the free tier run ~1.47s but properly indexed production calls hit ~50–60ms. Deployed to Heroku and it works, albeit slower on free tiers.
