Era

2024 – Present

Era is a personal, AI-powered financial agent that helps you understand your money, automate your finances, and grow your wealth. I implemented many of the core features of the product as an early design engineer at the company, with a particular focus on creating a web app that felt native on mobile devices.

For onboarding new users I created custom inputs with sound effects and haptics that make getting started with Era delightful and fun.

Allowing users to provide financial information manually means they can try the app before deciding to trust us with their bank data.

The core of Era is a set of agent-generated tasks, suggestions, and questions for the user to take action on in order to improve their financial health.

Era is able to automate certain tasks, such as recurring transfers to savings, in order to to help users put their finances on autopilot.
