Personal and business finance on one data model

What I tried

A bank account, a credit card and petty cash are the same person’s money, yet tracking them tends to scatter across separate tools. The attempt: hold personal and business use in one account/transaction model instead of splitting them into two products — with recurring and scheduled transactions on top.

What came out of it

The model held: multi-account management, budgeting, goals and reporting all ran on the same core. As load grew, event-driven pieces (Redis, RabbitMQ) came in, and the client side expanded from web to iOS and Android via React Native.

Where it ended up

The experiment turned into a SaaS product; subscriptions, mobile apps and business features live on the product side. Details in the portfolio.
