Experience

Ikigai

A React-based application that lets users create various models for data analysis. I was one of the front-end developers in a team of two. I bootstrapped the project and created the core engine for the user dashboard. I was also involved in brainstorming with the back-end developers to decide on APIs.

Reduce

Reduce is a Swift-based iOS application that allows users to calculate their carbon impact by analyzing the user's credit card transactions. I worked on the back end of the application using Express.js, Sequelize, Amazon RDS, and Plaid API.

Healthcare Application

A React-based application that provides various calculators to clinicians to calculate the risk of several diseases by providing information about the patient. Each disease has a different type of calculator, and the entire UI is data-driven. I served as the UI developer and delivered various features to the application.
