Experience

Audio Licensing App

An audio licensing app that makes finding and licensing music simple. It was founded by a collective of musicians and creative professionals who partnered with their clients to deliver on their vision while helping artists monetize their work.

The app has raised total funding of $2.75 million since 2018 and ranks 13th among 304 active competitors. The company previously used third-party tools that helped them make the app that did everything for them. We worked directly with its CEO and product management team. I started the project from scratch and delivered three operational phases.

Government Permit Issuance Tool

A microservice-based app built on Sinatra. The primary purpose of this app is to issue permits requested by citizens. When a citizen applies for a permit for a pet, building, etc., and submits all required documentation, staff members use the app to review and accept or reject it based on the information provided. It also calculates a dynamic fee based on the information filled in by citizens and handles all the payments. It assists local governments of all sizes with citizen notifications and online permits.

The goal was to facilitate government administrators' jobs, digitalize the paperwork, and make it easy for citizens to access the government portal online.

I joined the project as a developer and got promoted to team lead after adding many major and minor features to the app.

Student Assistance Application

An app that helps colleges and universities meet prospective students domestically and internationally. It helps K-12 districts and private schools connect their students with our network of over 1,800 colleges and universities.
