Experience
Numbrs
Numbrs allowed you to link all your bank accounts in one app, send money, and manage your expenses. It also featured a store where you could apply for bank accounts, credit cards, and loans. All the products in the store could be purchased remotely via VC, which wasn't that common of a feature at that time.
Airchat
An audio/video messaging app with a very unique UI. I worked on the main grid, a highly interactive RecyclerView implementation with rich gestures and animation, and the messaging recording and playback.
App for AOSP-based Intercom
I contributed to the development of Latch's intercom native app. I worked on enhancing the app's functionality and user experience, collaborating closely with a talented team to meet the project's goal and deadline.
Linux Kernel
I worked on a few features that landed in the Linux kernel mainline while working in the Linux kernel team at Meta. I implemented a few features in PSI and zswap, and also found and fixed two memory corruption bugs in mainline.
