A small studio
building one thing
for one audience.
Qarbi builds custom booking engines for Australian medical and allied-health clinics. One product, one audience, one durable wedge — ownership of the booking infrastructure that your competitors lease forever.
We spent four years building production ecommerce for AU mid-market retailers — marketplaces, B2B portals, Magento at scale. The work was rigorous and the clients were demanding. We learned how to ship software that runs for years without our team touching it.
Then we built Fabshaping — an Australian aesthetic-clinic platform with a custom booking engine and clinic dashboard. That's when we saw what Cliniko, HotDoc and HealthEngine actually cost a small clinic over five years. The same booking flow, rebuilt by us, would pay for itself in eighteen months and belong to the clinic forever.
So this is what we do now. One product. One audience. One pitch you can verify in fifteen minutes: does the math work for your clinic? If it does, we'll build it. If it doesn't, we'll tell you so on the call.
— Jack Nguyen, Founder
Vietnam team. Fabshaping-tested. AEST support.
Our engineering team is based in Ho Chi Minh City. We don't have an Australian entity, and we don't need one for what we do.
The trust signal is the work product. We engineered Fabshaping, an Australian aesthetic-clinic platform running production booking software in daily use. We know how it works under the hood, which is why our booking engines integrate with it seamlessly. Same team, same engineering rigor, now applied to clinics who want to RUN their own booking infrastructure instead of paying commission forever.
Practical bits: AWS Sydney hosting for your patient data, Australian Privacy Principles applied, AEST 9–5 support hours, founder reachable directly. AUD pricing, one-time fee, no FX surprises.
We chose this structure deliberately. It keeps build costs sustainable for a $10–18k one-time fee instead of the $40–80k a Sydney agency would quote for the same scope. And it keeps us focused on the product instead of the overhead.
Three people. Senior engineers, not subcontractors.
8+ years in production engineering. Led delivery for marketplace, B2B, and now booking-system builds across 8 countries. Founded Qarbi to fix the broken agency model — and now leads the studio's focus on Australian clinics. Jack is the person you'll talk to on your first call, and the one who stays involved throughout your engagement.
13+ years in enterprise consulting and digital transformation. Bach bridges the gap between business requirements and technical execution — translating what clinic owners need into what engineers build. This is why our booking engines ship features that move metrics, not just satisfy a scope document.
5+ years leading technical delivery for production systems — from Adobe Commerce builds handling 850+ orders/minute to custom booking engines and AI workflows on n8n, Node, and Anthropic/OpenAI APIs. Louis specializes in performance, integrations, and the engineering rigor that keeps booking engines running for years.
Four years of production work, repositioned.
Founded by Jack Nguyen during COVID. First production ecommerce engagement delivered for an Australian retailer.
200% growth in year one. Became implementation partner for Omnyfy (later Ultracommerce), shipping marketplace and B2B builds.
Omnyfy acquired by Ultracommerce. Partnership continued and expanded across mid-market retailers in 8+ countries.
Shipped 600+ enterprise features across marketplace, B2B, headless, and multi-vendor builds. Built Fabshaping — Australian aesthetic-clinic platform with custom booking engine and clinic dashboard.
Repositioned around Australian medical and allied-health clinics getting fleeced by booking SaaS commissions. Same engineering rigor, applied to giving clinics ownership of their booking infrastructure.
