Questions
How does the quote work?
You tell me the problem, I reply with an initial analysis, architecture proposal, scope and price — no strings attached. Fixed-scope projects have a fixed price; hourly work and consulting are billed per hour.
Do you work with a contract?
Yes. Every engagement starts with a contract defining scope, deadlines, pricing, confidentiality and intellectual property — the delivered code is yours.
Do you work remotely?
Yes, 100% remote for anywhere in Brazil and abroad. Occasional on-site work in the Porto Alegre/RS region when it makes sense.
Do you take over ongoing projects?
Yes. I run a diagnosis of the current code and infrastructure before taking over, to align expectations on timeline and quality.
What about after delivery?
Every fixed-scope project includes a warranty period for fixes. After that, I can continue on an hourly model for evolution and maintenance.
