Most trackers show a single net-worth figure and a green-or-red delta. That number is hard to act on. You know your balance, but not what it could comfortably fund, and the dashboard gives you no next step beyond watching it move.

The gap I wanted to close: turn portfolio performance into something tangible a monthly spending allowance, backed by yield, with clear milestones toward a goal.

I treated this as a product problem, not just a dashboard. The key decision was to lead with the monthly allowance as the hero metric, and demote net worth to context. That single reframing changes every downstream layout choice.

Because I was solo and timeboxed, I scoped the first version to one clear loop: pull live prices, visualize performance against a goal, project a monthly allowance, and let users set a target. I deliberately cut secondary ideas (social, alerts, tax views) so the core read instantly.

The two total-value numbers (portfolio vs. portfolio including the allowance) confused even me at first. If I rebuilt it, I would unify them into one clear figure with the allowance shown as a derived callout, removing the ambiguity.

I also have not yet done real user testing, so the current 'impact' is design intent, not measured behavior. The next step is to put it in front of a few users and validate whether the allowance framing actually changes how they think about their holdings.

That honesty about what is proven versus assumed is the part I am proudest of: the project shows a complete solo build and, just as importantly, a clear vector of how I would take it further.
