Frequently asked questions
How do you price a project?
Share your goal, the systems involved and your preferred timeline. After reviewing the requirements, I provide a proposal with scope, deliverables, pricing and terms. Each project is quoted individually.
Can you improve an existing system?
Yes. I can review existing websites, stores, modules and integrations to fix issues or add features. Compatibility and access to the source code are assessed before the proposal.
Do you work with international clients?
Yes. I work remotely with communication in English and Portuguese. Scope, time zones and progress updates are agreed in the proposal.
Is support available after delivery?
Yes. Maintenance, improvements and ongoing support can be included or quoted separately. The proposal defines coverage, support terms and the process for requesting changes.
