Get found on Google and inside AI answers
Half your customers still search on Google. The other half already ask ChatGPT. We prepare your site for both, and show you the number, not the promise.
Whoever holds your tech should earn the keys
We also run pentests, so we know exactly how an attacker would get in. That's why security and data protection are part of day one, not part of the post-mortem.

30 minutes, free. You leave with a written assessment, whether or not you hire us.
Projects that generate results
Real companies, real problems. Every project below is live and used every single day.
Eufis
Invoicing app for Brazilian sole traders. The government portal asks for over 20 fields; Eufis asks for two: how much you were paid and who paid it. It also tracks the annual revenue ceiling in real time, reads receipts from a photo and files a pre-filled tax return.
Kyon
An AI platform for clinics and medical offices. It answers patients on WhatsApp, reads documents, books appointments, and organizes records, so the front desk takes care of people, not paperwork.
Conecta Saúde
Continuous health tracking app for the whole family. Reads heart rate, blood pressure and glucose from wearables, calculates a health score and alerts the medical team before an emergency.
Andreia Câmers Real Estate
A complete platform for a realtor: property management, visit scheduling, admin area, advanced filters, and WhatsApp built in. The lead arrives and gets answered before it goes cold.
Ponte Sky Global
Website for a US immigration consultancy. Visas, passports, certified translations, and immigration processes explained clearly enough that Brazilians understand and trust the next step.
CSC Advogados
Website for a law firm: practice areas, attorney team, integrated contact form, and a restrained design that turns a visitor into a booked consultation.
Serra Verde Express
Uma das principais referências em turismo ferroviário no Brasil. Padronização de dados de produtos no ERP da empresa, com auditoria na base SQL Server, identificação de inconsistências que causavam falhas em vendas, financeiro e logística, tratamento completo e validações automáticas.
Marapet
Sistema completo de gestão de plano de saúde veterinário. Controle de beneficiários, coberturas, sinistros, rede credenciada e relatórios analíticos para clínicas e operadoras do setor pet.
Financial ERP System
A tourism group was running its finances across parallel spreadsheets. Today it runs an internal ERP with analytical dashboards in React + Django + MySQL. They close the month instead of reconciling it by hand.
Bank Reconciliation System
Wired straight into Itaú to reconcile corporate spending. It surfaced what nobody could see: $48k in unnecessary expenses eliminated in the first half of the year.
UaiMob
An AI-powered CRM for brokers and agencies: automated conversations, visit scheduling, and the full lead history in one place. No contact gets lost mid-conversation.
FinanceX Capital Consórcio
Landing page comercial para operação de consórcios, com foco em captação de leads, apresentação clara das modalidades e navegação otimizada para conversão.
FinanceX Capital
Site institucional da FinanceX Capital com estrutura enxuta em HTML, reforçando posicionamento da marca, serviços financeiros e canais de contato para novos negócios.
We built our own product before selling you yours
Salles Dev did not start from a business plan. It started from a problem nobody wanted to fix. With no investor and no team, our founder built his own SaaS from scratch and learned the hard way what a bad Friday night deploy really costs. That product is still live and brings in R$20k in monthly recurring revenue across real estate and healthcare.
That changes how we look at your project. People who only sell services think launch day is the end. People who run a product know it is the beginning: the server goes down after launch, the customer writes at 11pm after launch, the security hole shows up after launch. So we became a team of specialists in infrastructure, cloud, development, AI and offensive security (pentesting). An agency ships the website and disappears. We stay with the server, the system and the customer conversation.
Our mission: turn technology into real business outcomes, from the server to the customer reply, with no jargon and no drama.
Your sector has a specific bottleneck
We have already solved the tech problem of people who do what you do. Pick your sector and see the real case.
The patient called at 7:40pm. Nobody picked up. Tomorrow they book at the clinic down the road.
An AI agent answers, clears the doubt and books into the free slot — Sundays included.
See solution Real estateThe portal lead lands at 10pm. Whoever replies first gets the viewing.
Automatic reply the minute it arrives, interest qualified, viewing in the agent calendar.
See solution Law firmsThe client searches your name before calling. What they find decides whether they call.
A site that explains your practice clearly, shows up in search and turns visits into booked consultations.
See solution Finance and ERPThe spreadsheet balances, but nobody can explain where the number came from.
A system that talks to the bank, reconciles on its own and shows the origin of every entry.

From the server to the app, we pick the tool for the problem, never for the hype. Filter by area and see what we actually run.
