Shipped, in production.

Live systems with real users, payments, and uptime — not mockups. Each one built end to end: design, app, infrastructure.

    OS:CAR — oscarintell.com

    A frequency-therapy platform with a real-time audio engine, an AI guide with session memory, subscriptions, and a practitioner network. The heaviest build — product, payments, and AI in one system.

    Soul Report — soulreport.app

    A commercial platform that generates and sells personalised reports end to end — intake, generation, checkout, delivery. A product that earns, not a brochure.

/ capabilities

What we build.

Full-stack, end to end. A small team of senior engineers who own the whole thing — no handoffs to juniors, no account layer.

01 / Web platforms
Apps & surfaces

Next.js applications, dashboards, and marketing sites — designed and engineered as one. Fast, accessible, built to last.

02 / Payments
Revenue, wired in

Stripe checkout, subscriptions, invoicing, and retainers. Products that take money cleanly and reconcile properly.

03 / AI
Intelligence, integrated

Claude-powered features, spec engines, and agents woven into the product — not bolted on. The spec engine on this page is one.
