You shipped AI features — then the bill arrives, and every free user who never converts eats your Anthropic budget 24/7. This is the complete, production-tested Supabase + Claude backend that stops that: API key hidden from every iPhone, JWT-verified Edge Functions, 3-layer rate limiting, free-tier caps + cheap-model routing, caching (40–60% off), cost alerts — plus full Swift integration and a debug playbook. Built from a live ¥480/month app. Pairs with StoreKit 2 & Rejection Buster.
Pricing strategy for when your conversion is low, ARPU is stuck, or you're repricing and need a defensible recommendation — not a framework list. Diagnoses which of three decisions is at stake — packaging, metric, or price point — then applies the right framework and commits to specific numbers. Unlike generic AI that tours every framework, this picks what fits your situation, states a specific number, and flags what would change the answer.
Spent years studying what makes SaaS pricing pages convert — what gets people to click, what stalls them, what sends them to competitors. The skill behind this knows the psychological levers: tier naming, anchoring, the highlighted middle plan, the FAQ that defuses objections. It's not copywriting in a vacuum — it's copy that understands conversion.
Senior level payment integration guidance and code review across Stripe, Adyen, Braintree and PayPal; catches double charges, unverified webhooks, idempotency gaps and client supplied amounts before they cost you money, and guides provider selection, SCA/3DS, subscriptions, disputes, PCI scope and go live.
Launching doesn't have to mean failure. People might have reached their goal... and then stopped at one step. Reveal 1,000 visits → 100 signups → 10 activations → 3 payments, then isolate the next question.
