Experience

Ruby on Rails (RoR) Weather App

https://pleaseallowmeto.helpyourteamlove.life
A Ruby on Rails (RoR) weather app that takes an address as input and returns the weather at that location. The system caches results in Redis for 30 minutes, considering the zipcode or Geohash if no zipcode is available. This project indicates my expertise in full-stack capabilities and coding: https://github.com/cortfritz/wthr.
