Software to manage private residential neighborhoods — access control, fee payments, and more.

The project

In my city, private neighborhoods are very popular. I was first approached by one of them; they needed a software solution to manage all of their processes. I built it from scratch in three phases.

  • Phase 1 was the development of a mobile app and a web app so the committee could manage information about houses, share messages, schedule events, and manage security personnel. Individual residents could manage their visitors and generate access codes.
  • Phase 2 included a payment system. Residents can pay with Stripe or bank transfers, and the committee approves or rejects each payment. This phase also included reports for all payment information.
  • Phase 3 connected the platform to a ZKAccess C3-400 access control system. We built the integration to activate or deactivate user access; residents who had not paid were disabled through a scheduled job. I also built reports for access using RFID tags.

I then offered this solution as a SaaS product to two other private neighborhoods.

My participation

I personally built the entire solution myself: the app, the API, and a Windows service that connects to the C3-400 controller for the access doors. I deployed it on a DigitalOcean VPS and used Spaces (S3-compatible) for media storage.
