Petside

The problem

Consumer social products fail on trust: people will not upload years of pet memories to something that might lose them. That makes correctness and observability a product requirement, not an engineering preference.

Approach

• Treat the test suite as a launch gate rather than an afterthought.
• Wire real error monitoring before launch, not after the first incident.
• Verify claims against the deployed site rather than the local build.

Architecture

• Supabase Postgres with row-level security on all user content.
• Stripe for subscription billing; Capacitor for iOS and Android from one codebase.
• Sentry on both browser and edge, plus real-user web-vitals collection.

What shipped

• Memory book, milestones, and local playdate discovery.
• Native mobile builds and subscription billing.
• Error monitoring that surfaced and fixed a logger defect collapsing 25 distinct error sites into a single issue.
