Custom web apps, built to last and to grow.

Not a brochure site and not a template — a real web application that runs part of your business: bookings, payments, dashboards, internal tools, customer portals. We’re a small studio that pairs careful design with modern engineering and AI integration where it actually earns its place, working closely with you from first brief to launch. Built bilingual (English + Spanish) by default, and delivered remotely to clients worldwide.

Where a web app beats a website

A website tells people about you. A web app does work — it takes the booking and the payment, syncs the calendar, runs the dashboard your team checks every morning, powers the portal your customers log into. If you’re stitching that together with five disconnected SaaS tools and a spreadsheet, a focused custom app usually pays for itself in the time it saves.

What makes ours different

Bilingual by default. Every build ships English + Spanish — useful if you sell across the Americas or to a mixed audience. Fast and maintainable. We build on a modern stack, pass Core Web Vitals, and hand over something your next developer won’t curse. AI where it earns its place. We integrate AI for the parts that genuinely benefit — search, drafting, classification — not as a gimmick. Small-studio attention. You work with the people building it, brief to launch, not an account manager.

Typical builds

Booking and scheduling systems with payment. Customer or member portals. Internal dashboards and admin tools. Catalogue / ordering apps with a payment gateway. Lightweight CRMs and lead pipelines. Marketing sites with a custom backend. If it lives in a browser and has logic behind it, it’s in scope.

How we work, remotely

We start with a short discovery call to pin the real problem and the smallest thing that solves it, agree a fixed scope and price in writing, then design, build and launch in clear stages — no surprises on the invoice. Everything happens over calls, email and WhatsApp, so it works the same whether you’re in Lima, São Paulo, Miami or London.

Frequently asked

Do you work with clients outside Peru?
Yes — custom development is delivered entirely remotely. We work with businesses across South America, North America and Europe. The studio is Lima-based, which also means competitive rates for the quality of work.
Website or web app — which do I need?
If you mainly need to be found and tell your story, that’s a website. If you need software that does work — bookings, payments, dashboards, portals — that’s a web app. On a discovery call we’ll tell you honestly which one your case calls for.
What does it cost?
It’s scoped per project, because a booking widget and a customer portal aren’t the same job. We agree a fixed price in writing before any work starts. Custom builds start higher than a standard site (which begins around $1,500) and are quoted after a short discovery call.
Will I be able to maintain it?
Yes. We build on a mainstream, well-documented stack and hand over clean code and docs, so you’re never locked to us. If you’d rather we keep looking after it, ongoing Care is available.
