iTechSIM

Overview
A travel-eSIM platform I co-founded with an Australian team and built myself — web, iOS and Android, payments, and automated eSIM delivery. So far: $4.5K+ in sales and 350+ eSIMs for trips to 22+ countries.
iTechSIM sells prepaid travel data for 50+ destinations. A traveller picks a country, pays, and gets a QR code within seconds — online the moment they land. I co-founded it with an Australian team and build the entire product myself: the web storefront, the iOS and Android apps, checkout, fulfilment, and the operations tooling behind it. So far it has delivered 350+ eSIMs for trips to 22+ countries, with $4.5K+ in sales.
The heart of it is a commerce pipeline. A nightly sync pulls the wholesale eSIM feed into Supabase with rule-based retail pricing. Stripe Checkout — Payment Element, Apple Pay, Google Pay, Link, promo codes — and an independent PayPal rail handle the money. A webhook-driven fulfilment flow provisions each eSIM with the supplier and delivers the QR, with operator alerts on failure and refunds wired to both payment providers.
Around the money path: magic-link auth with a usage dashboard, verified-buyer reviews with pre-publish moderation, an admin panel for pricing rules, orders and refunds, transactional email for delivery, usage alerts and review invites, consent-gated analytics via Google Consent Mode v2, Sentry error tracking, and a full staging environment mirroring production.
The way it gets built is half the story: an AI-native workflow where I design in Claude and implement in Claude Code, shipping one feature at a time. A working MVP went live in a week; a marketing-ready feature set followed within three. Beyond the code, I shape the roadmap, the marketing, and the plan to grow it together with the founding team.
