Software studio · Brazil · working in English
We design, build and run web apps and SaaS products for startups and small businesses. You talk directly to the developer by email or chat, get a fixed quote before any work starts, and own all the code.
From a first version to test an idea to new features on a product that already has users.

Online booking, availability rules, staff calendars, reminders and cancellations without double bookings.
Payment links, recurring plans, trials, overdue handling and the admin screens to manage them.
Replace spreadsheets and manual work with a simple web app your team actually uses.
Connect your product to email, messaging, payment providers and the APIs you already use.
Take over a backlog, fix bugs and ship new features on a JavaScript codebase you already have.
★Case study
A subscription product for salons, barbershops, personal trainers and other appointment-based businesses in Brazil. It is live at agenda.kodeira.com.br (in Portuguese), with a free trial and monthly subscription plans.
Simple, transparent and with no surprises on the invoice.
No account managers. You talk to the person writing your code by email or chat, and every decision stays documented.
We are in Brazil (UTC−3): mornings overlap with the US East Coast and afternoons with Europe.
Code, data and accounts are yours. No lock-in, and everything is documented for whoever comes next.
Most projects get a fixed price for an agreed scope. For ongoing work, such as maintenance or a backlog, we can work with a monthly retainer.
Invoices in US dollars or euros. A typical project is split into a deposit and milestone payments tied to working software.
Mostly JavaScript on the front end and back end, running on Cloudflare (Workers, Pages, D1, KV). We can also work on your existing stack if it is JavaScript-based.
No. We work asynchronously by email and chat. You get written answers you can reread, share with your team and keep as a record of what was agreed.
Yes. We are happy to sign an NDA before you share details about your project.
Send a few lines about what you want to build and your timeline. We reply within 1 business day.
