Work Experience

Senior Front-end Engineer

  • Built the mobile app with React Native, using both open source and proprietary libraries to cater to the mobile audience.

  • Migrated a huge part of the codebase to TypeScript, writing custom definition packages for libraries without existing types.

Experience

Caretaker

https://www.usecaretaker.com
A real estate management solution that aims to replace traditional paper-and-pencil ways of keeping records, disbursing payments, and managing property issues and eliminates the stress of property and facility management. I developed the web app in React and the mobile app in React Native. I also had to abstract state management into a separate library to reduce code duplicity and possible bug points.

Stencyl

https://christiandrey.github.io/stencyl
A custom extensible rich text editor built in React, Tailwind CSS, TypeScript, and Slate useful for applications, such as resume generators and form fillers, that need to create dynamic documents that require user input.

Docutrove

A digital platform to access legal documents and legal experts easily. I built the front-end web application using React and TypeScript and connected it to the back end using the provided REST API endpoints.
