Frequently Asked Questions
We work with the most robust stacks on the market, including JavaScript (React, Node.js, Vue), Python (Django, Flask), Java, .NET, as well as cloud technologies such as AWS, Azure and Google Cloud Platform. We select the ideal technology based on your project's needs.
We conduct an initial immersion (Discovery) to understand the project scope. Based on that, we present a detailed schedule and transparent quote. We work with agile methodologies (Scrum/Kanban) to ensure continuous delivery and full visibility of progress.
Yes. We offer support and evolution packages (SLA) to ensure your software continues to work perfectly, receiving security updates and new features as your business grows.
Absolutely. In custom software development contracts, all source code and documentation generated belongs 100% to the client after delivery and project completion. We guarantee this in the contract.
Yes, we are experts in system integration. We analyze your current infrastructure and develop APIs and middlewares to connect your legacy systems with new digital platforms securely and efficiently.
Timelines vary by scope. A focused MVP typically takes 6–10 weeks, while a full platform with multiple integrations can take 3–6 months. We define a realistic schedule during our initial Discovery phase so you have clear milestones from day one.
We work with both. Whether you're a startup building your first product or an established company modernizing operations, our Squad model adapts to your stage, budget, and pace. What matters is that you have a real business problem to solve.
We offer both. Fixed-price contracts work well for well-scoped projects with clear requirements. Time & materials suits evolving products or ongoing dedicated teams. We recommend the right model after the Discovery phase, once scope and complexity are well understood.
Yes. We offer a paid Discovery phase where we map your requirements, define the architecture, and deliver a detailed roadmap. It's a low-risk way to experience how we work before committing to a full project.
Yes. Our team operates fully in English and Portuguese. We have delivered projects for clients in the United States, Europe, and Latin America, and our entire delivery process — documentation, sprint reviews, and communication — runs comfortably in either language.
We follow agile sprints with regular reviews where you see working software, not just status reports. Day-to-day communication runs through Slack or your preferred tool, and all tasks are tracked in ClickUp or Jira. You always know what is being built and what comes next.
You get a dedicated Squad — a cross-functional team (developer, QA, tech lead) allocated exclusively to your project. We do not share resources across multiple clients simultaneously. Your squad becomes a direct extension of your team.
Scope changes are a natural part of software development, and we plan for them. New requirements are evaluated, prioritized, and incorporated into the next sprint or documented as a change order. We never begin out-of-scope work without your explicit approval.
