- Collaborated with a team of awesome developers and designers to create a Cruise mobile application from almost the ground up using React Native, TypeScript, Redux, and Storybook.
- Created screenshot testing for a React Native application with Storybook from scratch with a screenshot plugin I developed. Used stories for code coverage.
- Developed the back-end side of the application. Created requests for the front-end side in TypeScript.
- Created multiple animations with React Native Reanimated.
- Upgraded all dependencies in the project, including the React Native version from 0.66 to 0.71 and TypeScript version from 4.4 to 5.0. Cleaned up unused dependencies.

- Utilized functional programming features using fp-ts, thus reducing the scope of potential bugs in the application and imposing immutability, which is particularly important while working on such large-scale applications.
- Used Storybook to integrate and collaborate better with the design team.
- Wrote the back end in Node.js with NestJS and TypeORM, so I received tickets for back-end bugs and features.

Experience
Running Windows Server on MacOS
I worked at a company that was running a Windows Server for development, and I was using MacOS at the time. To run the server, I was required to either dual boot my laptop with Windows or run the whole programming environment on Parallels virtual machines (VMs).
I did not like either option, so I came up with a hack that allowed me to use my MacOS environment instead of Windows. I did this by sending requests to the Windows Server on the Parallels that was running Windows. Basically, I was forwarding requests on specific localhost ports to Parallels.
Also, as I did not want to see anything from another OS on my MacOS screen, I wrote a small Bash script that was running Windows on Parallels, and I ran Windows Server in Windows VM. All of this was happening with a minor command on one small terminal. The feeling of the accomplishment was astonishing.
