Project History
Kompliant
https://kompliant.com/Set up all of the agile ceremonies for a team of eight developers, one designer, and a (junior) product manager. I led the team to take their first product to market and completed all required user testing with some friendly customers.
Realtor.com / Rocket Mortgage Integration
Led a team of engineers and a designer to integrate a unique offering from Rocket Mortgage into the Realtor.com website, which thousands of people visit daily.
During this project, I defined the product to be built, wrote out all the user stories, managed the Agile ceremonies, and worked collaboratively with my team to deliver it by the deadline. It was a great success!
Buckle Up App
https://youtu.be/SNUpc0-v2CUFounded Buckle Up, which became the most popular mobile application in its category.
I created the product roadmap and managed a small team of international outsourced developers. I did hundreds of interviews and product demos to receive feedback from real users.
Initially, I marketed to people traveling from city to city. However, I realized many of my users traveled to and from music festivals, and my CAC was too high. So, I contacted multiple music festivals in Australia and developed partnership deals with 42 of them who could market to their ticket buyers. I created a widget that I requested they put on their checkout process. It said: "Looking for a ride? Have spare seats and want to pay off some of your ticket? Download Buckle Up."
After implementing this strategy, my weekly ride count went from around 30 per week to over 3,000. I came to San Francisco looking for funding and, in the end, didn't raise money but received an amazing job offer!
Giddiup App
https://youtu.be/V-D0QpXi3YEServed as the product lead for Small World Social, where we developed a product called Giddiup. Managed a team of 13 and worked with the leadership team to develop the product strategy, roadmap, and vision.
In addition, we developed a car-sharing marketplace similar to Getaround or Turo in the US, where vehicle buyers could list their car when they weren't using it. All money earned through car-sharing would pay off the funding that the user received through the app. Also, if users weren't approved for funding, they had an opportunity to rent a vehicle instead of buying it, which means that no user was left without an option.
Our tagline was "Get a car in five minutes," and we believed we could make that happen for every user, either by purchasing or borrowing a vehicle.
Voycap Platform
https://youtu.be/MlQysH7dZxcLed the product discovery phase and design of the Voycap platform. Worked with the developers to confirm sprints were completed on time and performed all QAT to make sure it was developed as specified.
Mobile App for Creating Registries and Buying Gifts
https://www.shoptings.com/Led the small team to design, build, launch, and scale a mobile application for creating gift registries and allowing users to buy gifts for others.
DaVita (Mobile App for Doctors)
https://davita.com/Built the roadmap and led the development team to create many features within an existing mobile application to help doctors take better care of their patients.
Founder at Web3 Daily (Sold to Milk Road in August 2024)
https://www.web3daily.co/Built, scaled, and ultimately sold a crypto/AI media company called Web3 Daily over 2.5 years. We sold it to our main competitor, Milk Road.
Web3 Daily was an amazing journey, and it was great to build and sell the company all within 2.5 years.
