Media buyers and affiliates run paid traffic but have no simple way to know when conversions stop happening. Analytics tools show you data after the fact. Error monitors catch code crashes. Neither tells you "your checkout broke 2 hours ago and you've lost $500 in conversions." This gap costs real money.
What It Is
Conversion sanity check for websites. Alerts when something breaks and shows the revenue impact. Not analytics, not error monitoring — more like Uptime Robot for conversions. Built for affiliate marketers, media buyers, and solo founders running paid traffic.
What I Built
Full-stack SaaS with event sourcing architecture. Session stitching across pageviews. Conversion baselines that learn normal patterns. Incident clustering to group related failures. Warning generation with revenue impact estimates. Multi-surface product: marketing site, app dashboard, docs, onboarding, admin panel, JavaScript tracking SDK.
The Outcome
First paying customer acquired from $3 ad spend. Product handling real production traffic. Largest solo SaaS build to date — proved I could ship a complete product, not just MVPs.
