        Start with the AI & Automation assessment

        The short "AI & Automation assessment" form helps us understand your company’s maturity level. The key question is "Which statement best describes you today?":

        • We don’t use AI yet
        • We use AI individually (ChatGPT, Gemini, etc.), with no standard
        • We have defined AI uses in some processes
        • We have AI integrated into our systems
        • We have AI agents automating processes end to end

        From there, we cross your case with market tools we already use in the assessment — for example Claude and Claude Code (Anthropic), GPT and Codex (OpenAI), Grok Bot (xAI), Gemini (Google), Perplexity, n8n, Devin, Kiro (AWS) and Manus — to point out which combination makes sense (and when Amazon Bedrock inside your own AWS account is the safest path). That way, the first conversation starts with what matters.

        See how we choose the right AI tool for your case.

        Frequently asked questions

        Common questions about AI, automation and AWS

        AWS migration

        How long does an AWS migration take?

        It depends on the size and complexity of your environment. The assessment (1–2 weeks) produces a wave plan with an estimated timeline for each step.

        Will my operations stop during the migration?

        The plan aims for minimal impact: a pilot migration, agreed windows and a rollback plan for each step.

        Will I know my monthly AWS cost?

        We provide an estimate based on your actual usage, built with the AWS Pricing Calculator, and set up budgets and alerts.

        Do you migrate databases?

        Yes. We choose the right strategy for each case (for example AWS DMS or backup and restore) and validate the data at the end.

        AWS cost optimization

        Do you need full access to my account?

        No. The assessment uses a read-only IAM role that you create and can remove at any time.

        How much will I save?

        We don’t promise a percentage before analyzing your account. The report shows each opportunity, its mechanism and an estimate calculated from your own data.

        Can cutting costs affect availability?

        Every recommendation comes with its risk. Production changes are only made with your approval and a rollback plan.

        What is FinOps?

        The practice of continuously tracking and optimizing cloud spend, bringing together engineering, finance and business: visibility (tags, reports), optimization and governance (budgets, alerts, monthly reviews).

        AI & automation consulting

        Where should my company start with AI?

        With the process that takes the most team time and follows clear rules. The assessment helps pick that first use case.

        Is my data safe when using AI?

        We propose architectures inside your AWS account, with encryption, least privilege and logs. On Amazon Bedrock, your inputs are not used to train the models.

        What’s the difference between automation and an AI agent?

        Automation follows fixed rules (if X, do Y). An AI agent interprets text and requests and chooses the next step within defined limits. Many solutions combine both.

        How much does it cost to run an AI solution?

        It depends on usage volume and the chosen model. We estimate monthly cost before building and set spending alerts.

        Which AI tool do you use — Claude, GPT, Gemini or another?

        None as a one-size-fits-all recipe. In the assessment we look at the process, the data and the risk; we use market tools we already know in practice (Claude/Claude Code, GPT/Codex, Grok Bot, Gemini, Perplexity, n8n, Devin, Kiro and Manus, and, where it fits, Amazon Bedrock inside your AWS account) and recommend the combination that best matches the case — sometimes the best answer is automation with no generative model.

        Claude Code vs Codex: which do you recommend?

        It depends on the team, the repository and the type of task. Claude Code and Codex (OpenAI) are strong options for coding agents; in the assessment we compare quality, cost, data limits and how each fits your workflow (including Grok Bot in Cursor, Devin, or Kiro on AWS when the scenario calls for it). The choice is documented in the MVP plan.

        Do you work with n8n or only with AWS?

        Both, when it makes sense. n8n shines at fast automations and integrations between systems; on AWS we use Lambda, Step Functions and EventBridge when the flow needs scale, infrastructure as code and governance. The assessment tells which path (or both) fits your process.

        How we work and hiring us

        How does a project start?

        With the AI & Automation assessment form and an intro call, followed by the paid assessment (1–2 weeks), the MVP and, if it makes sense, monthly evolution.

        What access do you need?

        The minimum required. For the assessment, read-only access (a read-only IAM role on AWS). Write access only during implementation, with defined scope and duration, and removed at the end.

        How do you handle personal data (LGPD/GDPR)?

        We process only the data needed for the service, under an NDA and data-protection clauses in the contract. See our Privacy Policy.

        Do you work with clients outside Brazil?

        Yes. We work remotely with international clients in English; contracts and billing [in USD — terms to be defined by Sergio].

        Which time zone do you work in?

        Brasília time (UTC-3). Meeting hours for North American and European clients: [to be confirmed by Sergio].

        Which industries do you serve?

        Companies across many industries. We work with companies from many sectors. Due to prior contractual commitments, some segments are not served at this time.
