Alosant

https://www.alosant.com/
Alosant is a branded mobile app platform for communities. That's a nifty app with a custom content management system (CMS), customer relationship management (CRM), ecommerce features, event schedule, and programmable chat.

Many features were unique to a specific community, like integration with alarm systems or beacons. I integrated the application with Stripe, Square, Eventbrite, Zendesk, Caliber, Facebook, and HubSpot.

I led the development of this project's Rails back end and the React web app.

SwimUp

https://swimup.io/
SwimUp is a mobile app for swimmers. I built the Rails back end and all the non-visual parts of the React Native app. The app was intended to be used offline, so it had a lot of logic implemented in JavaScript.

A video conferencing software for large teams offering many features that major competitors missed. I was the back-end developer who handled features like a custom SaaS subscription subsystem and the signup flow. Also, I've performed several performance optimizations, like migrating the frequently updated data from PostgreSQL into Redis.
