Experience

Employee Satisfaction CRM

My employer held a competition internally to ideate a new product when I only had three months of work experience. I presented my idea for a CRM focused on employee satisfaction and it was accepted. I was given a team of four developers, and we were able to release the product in six months. By the time I left the employer, we had served over 100 businesses and had a net promoter score of 47.

Invoicing System

Served as the lead back-end developer for a web-based invoicing system with mobile apps, similar to Zoho Invoice, QuickBooks, or Xero. Had to handle end-customer data, track employee timesheets, integrate with payment processors, and create basic accounting reports.

Transport App

The idea for this project was to collect and show information about how to get to a destination or place. Users can use this application to search for a destination and get transportation info about possible ways to get there, e.g., using a bus or lending a bicycle.
I developed this application using Mapbox APIs.
