$4,500 - dev for pool construction company dashboard needed

Context on the contract: We need a developer to take on a 3 month ($4,500 USD) project to build an internal management tool for a pool construction & maintenance company. After the initial 3 months the project will go into a upkeep and maintenance mode where we will order changes on-demand (~600 USD per month). Context on the company and on the product: We currently use an exisiting software system called POM. We use this system to dispatch employees to pool as well as to manage construction projects. The software system we us is missing features that we need. We decided the right thing to do is just to build the system ourselves. I am looking for 1 person to take on this project, not a team of developers. The stack we are looking to use is a claude code assisted build using react-native and supabase with a web-app version for the office to use and native apps for the field workers to log into.
