Everyday Life Insurance
A fully-integrated online experience for a life insurance startup. It consists of an interview funnel that collects information about the user. That information is fed into a proprietary recommendation algorithm that I codified. The recommendation tells the user how to ladder life insurance policies to best meet their needs. Integrates with third-party insurance providers to provide quotes.

Savvy Insurance
The easiest way to shop for insurance! The user is able to obtain accurate insurance quotes without needing to manually enter information.

This is done by providing users the ability to log in with their current insurance provider. Upon logging in, all of the user's information is used to provide them with quotes from other insurance providers. This allows users to easily check if they can get the same coverage for a better price.
