App for Landlords of Properties
I contributed to this app while working at Different Technologies, a successful property management startup in Australia.
I led the team who started the transition of this app from native to React Native. It was an interesting project where I learned a lot about property management. This app had push notifications, maintenance approval requests, in-app chat, documents management, and more.

App for Distributed Worplaces
https://upflex.com/While working for Calcey Technologies, I got the opportunity to work on a platform called Upflex. It's a solution that makes distributed work simple, seamless, sustainable, and secure.
I came in the middle of the project but was assigned to fix major performance issues with the in-app map and booking system overall. I successfully refactored problematic implementations and also contributed to making the real-time booking system using a socket implementation. This is where my love for React Native started.
