Claude AI consulting

Bring Claude into your company, the right way

Buying licences is the easy part. Most of the value comes from connecting Claude to your documents and tools, and from teaching people where it helps.

Fatima Software is an independent consultancy and is not affiliated with Anthropic. Claude is a product of Anthropic.

  3. Week 3 · Build. Prompts, templates and small automations for the chosen workflows, plus Claude Code set up for your developers.
  4. Week 4 · Training. Hands-on sessions per team, a written playbook and a before/after measurement of time saved.

How a project runs

From first call to Production

Every change moves through clear stages, with a check at each step.

  1. Discovery

    Scope the problem

    One call to understand the data, the users and what "done" means. You get a written scope and a fixed quote.

  2. Build

    Build and test

    Working software against a copy of your data, with automated checks written alongside the code.

  3. Dev

    Try it early

    Every change deploys to a test environment automatically, so you can try it the same day.

  4. QA

    Validate with your team

    Results compared against numbers your team already trusts. Nothing moves on until they match.

  5. Production

    Release and hand over

    Approved release, documentation and a handover session. Optional support retainer afterwards.

About

Why "Fatima"

Fatima Software is the consultancy practice of FAT Software LLC, working from Asunción, Paraguay. The name honours Our Lady of Fátima, Nuestra Señora de Fátima. Our emblem shows her white mantle and the gold star on her hem, with the sun's rays behind her.

For us it stands for the way we want to work: honestly, with care, and in service of the people who depend on the software. Some clients need their whole company set up: a website, business email, accounts and security. Others need a Claude rollout for 50 people, an MVP for investors, or a report that matches the ERP to the cent. You deal with one person who knows your systems end to end.

From Paraguay I share working hours with the United States and the rest of Latin America, and I work in English and Spanish.

Every project is done as well as if it were our own.
