Each of these is a working product you can open and click through. They are self-initiated concepts, and we label them that way, but none of them is a mockup.

The operations dashboard for a small online brand: orders, payments, refunds and WhatsApp notification status in one place.
A redesign concept for a dated clinic website. Same business, same content, but now it answers patients' real questions and leads to a booking.
A mockup shows one moment. Production has to handle loading, failure, success and someone on a slow phone. We design those states with the same care, then build them with the same component.

Most vendors handle one layer and hand the rest to someone else. Problems usually happen at those handoffs. We cover all three layers, so there aren't any.
Layer 1
What your customers touch
Websites, redesigns and the custom applications your business runs on.
Layer 2
What makes it actually work
Payments, WhatsApp messaging and the APIs that connect your systems.

Layer 3
What keeps it running
Deployment, infrastructure, monitoring, and ongoing care.

Seven steps, each ending with something you can see, click or sign off. You'll never have to wonder what's happening.
You get: A written scope: what we'll build, what we won't, and what it costs.
You get: Clickable designs of the key screens, reviewed with you before any build work starts.
You get: A preview link that updates as we work, so you can see progress every week.
You get: Payments, WhatsApp and APIs, working in test mode end to end.
You get: Real devices, slow networks, failure cases, accessibility checks.
You get: Production on your domain, with backups, monitoring and a runbook.
You get: Measure what real users do, then improve it. Optional monthly care.
We're a young studio, and we'd rather tell you that than invent testimonials. Instead, here are the rules we work by, and work you can test yourself.
Everything in our work section is marked as client work or a self-initiated concept. We don't show invented clients, testimonials or metrics.
Your repository, your cloud accounts and your payment and Meta accounts, with documentation. You can leave at any time and take it all with you.
The person who designs the checkout knows how the webhook behaves. That's how details survive from mockup to production.
Before we start, you get a scope document listing what's included, what isn't, and the price. If something changes, we agree on it in writing.
Websites and redesigns, booking systems, dashboards and portals, and integrations: payments, WhatsApp, APIs and deployment. Usually for small and medium businesses, startups, and agencies that need a build partner.
It depends on scope, so we price each project after a short discovery call. You'll get a fixed price for a fixed scope in writing before any work starts.
The current pieces are self-initiated concepts, and each one is labelled that way. They are fully built and you can use them. Client work will be added with the clients' permission.
Yes. We build frontends, animation and integrations behind your brand, inside your process.
Yes. We start with a short audit so we know what we're working with, then fix, extend or maintain it.
You get documentation and full ownership. If you'd like, we stay on for monthly care: updates, fixes, performance work and new features.
Three short questions. No twenty-field questionnaire, no sales call before we've even read your brief.
