tracks

What I deliver

Three clear tracks. Pick the one that solves your problem — or I'll help you figure out which.

  • 01

    Software Builds

    Technical consulting and custom development. Architecture, code review, mentoring — and when it makes sense, I build from scratch: web, APIs, integrations.

    Who it's for

    Companies with a digital product, or that need one.

    What I deliver

    • Distributed systems architecture
    • Web applications and APIs development
    • Code review and technical audits
    • Engineering team mentoring
    Talk about Software
  • 02

    Applied AI

    I find where AI creates real value in your business and implement it: LLM automations, agents, RAG over your data, integration with Claude and OpenAI.

    Who it's for

    Companies that want to use AI but don't know where to start — or started in the wrong place.

    What I deliver

    • AI opportunity diagnostics
    • LLM automations (Claude, OpenAI, Gemini)
    • Business-specific agents and assistants
    • RAG over internal data (documents, knowledge bases)
    Talk about AI
  • 03

    Tech & Processes

    Diagnosing operational bottlenecks, choosing tools, modernizing stacks, adopting technology responsibly.

    Who it's for

    Companies that are growing but where processes have become the problem.

    What I deliver

    • Bottleneck diagnostics and process mapping
    • Tool selection and integration
    • Legacy stack modernization
    • Technology adoption roadmap
    Talk about Processes

§ 03

how I work

Four steps, no mystery.

From first contact to handoff. No black box, no surprises.

  1. 01

    Initial conversation

    Free 30-min call to understand the problem and see if it makes sense for both of us.

  2. 02

    Diagnosis & proposal

    Context analysis, clear scope, timeline and investment estimate — always in writing.

  3. 03

    Execution

    Incremental delivery with you involved closely. Short demos, decisions made together.

  4. 04

    Delivery & handoff

    Code, documentation, and team training when it makes sense. You stay autonomous, not dependent.

§ 04

frequently asked

Before you message

  • How does the first conversation work?

    A 30-minute call, free and with no strings attached. I'll tell you if I can help and how. If not, I'll recommend someone who can.

  • Do you work remote or in person?

    Remote by default (Brazil, GMT-3). Occasional in-person work in São Paulo is possible for clients who need it, arranged case by case.

  • What's the typical project timeline?

    Depends on scope. Mentoring and reviews: 2 to 4 weeks. Development projects: 1 to 4 months. Ongoing engagements: month-to-month.

  • How does billing work?

    Fixed-price project with clear scope, hourly for one-off needs, or monthly retainer for ongoing support. The model is spelled out in the proposal.

  • What size of company do you serve?

    From solo founders to mid-sized companies. For large corporations I typically work with specific teams, not at the organization-wide level.

  • What stacks do you work with?

    Core in .NET, C#, Azure, and AWS. Pragmatic in Node, Python, Next.js, and whatever the problem needs — I won't push my favorite stack if another one solves it better.
