CASE STUDY: FINANCIAL INFRASTRUCTURE
YieldHacker.
A Canadian rate aggregation protocol and real-time alert engine. From idea to production launch in 14 days.
Duration
14 Days
Primary Stack
Flask + React
Scope
Aggregation + Alerts
The Challenge
Canadians shopping for high-interest savings accounts (HISAs) or GICs waste hours manually checking 30+ bank websites. Rates change weekly, and promotional offers are buried in fine print.
01.
Rate fragmentation across 30+
institutions.
02.
Zero notification logic for rate
spikes.
03.
Fine-print promo capture (e.g.,
90-day 5.5% boosts).
The Solution
We engineered a high-throughput scraping engine that updates daily and sends targeted email alerts via SendGrid when better yields are detected.
