What tech do you use?

Modern stack: React/Next.js frontend, Node.js or Python backend, PostgreSQL/MongoDB database, AWS or GCP hosting.

Do I own the system? Can I take it elsewhere?

Yes. The source code is 100% yours. We deliver with full documentation so any other team can continue.

How long does post-delivery support last?

90 days included in the project, with 24h SLA for fixes. After that, we offer monthly maintenance plans.

How does pricing work?

After the initial (free) briefing, we send a detailed proposal within 5 business days, including scope, timeline and investment. You only commit when 100% comfortable.

Do you work with contracts?

Yes, always. Every project starts with a contract detailing scope, timeline, fees, IP ownership and post-delivery support.

How is payment structured?

Usually in 3 installments: 40% at start, 30% at mid-project, 30% at final delivery. We accept transfer, Pix, boleto and credit card.
