The project

Lever is a smart digital wallet platform that helps consumers optimize credit card rewards, track spending, and improve credit scores. Considering this, we were asked to develop a tool to help young adults select the right card while shopping online.

A challenge worth sharing

For this to work, we had to collect information on all reward programs across the USA and train a custom-made suggestion algorithm. Once the algorithm trained, we implemented it as a Chrome extension that could be used from any e-commerce website.

Securing payment data

We created a web app for users to upload and edit credit card information. The extension can auto-fill any credit card field during the checkout process. This data is securely protected by a PCI-compliant system.

The ranking system

When the extension detects that the customer is on the checkout page, it activates and displays all of the user’s available credit cards from best to worst based on their shopping goals.

Testing and fine-tuning

For Lever to succeed, it was of utmost importance for the Chrome extension to work on every e-commerce website. This was the most challenging step to overcome, as it needed to be perfect for us to make the official release.

Highlights

After six months of dedication with our team of two developers and one project manager, we released Lever’s MVP. After two years of great work, our team continues to deliver new features and support.

This was our first time creating a Chrome extension. We learned a lot along the way, and we delivered a successful project enjoyed by hundreds of users.

The project started with two of our top developers, Mauro and Franco, and eventually scaled as the requirements changed. We worked on front-end, back-end, and data scraping.

Data scraping bots were created to periodically access US banks’ public information and to keep the credit card rewards database updated.

We followed an Agile methodology, running two-week "sprints", and performing demos twice a month to show progress, receive feedback, and make small, incremental releases.

"Lever was a fantastic and challenging journey, we built it from scratch without precedents and it became a market model in a few months. A fantastic idea. no doubt"

The result

The Lever ecosystem is still expanding, with new tools and features to come. Right now, it consists of a landing page and a Chrome extension that can be fine-tuned by the user from the web app.
