Credit Card Optimizer
Decision engine to maximize rewards across complex card ecosystems.
Status: PrototypeNext.jsTypeScriptMath/OptimizationCSV/JSON inputs
Problem
Reward ecosystems are complex: category multipliers, caps, transfer ratios, credits, and edge cases. Most people can’t reliably compute best-card decisions.
Solution
A decision engine that compares cards and recommends optimized setups (one-card to multi-card) using configurable assumptions and transparent math.
What I built
- Optimization logic for multi-card setups and categories.
- Configurable assumptions (value per point, caps, multipliers).
- Outputs as clear recommendations and comparisons.
Next
Add an import format for monthly spend + a “diminishing returns” model to find when complexity stops paying off.
