    Migration of legacy Java systems to current Spring Boot, with tests and automated deploys, without stopping operations.

Why FerAlfeldDev

  1. 02.1

    You talk to the person who writes the code.

    No account manager in between and no handoff to a junior. The person who understands the problem is the one who solves it.

  2. 02.2

    Built to hold up in production.

    Automated tests, continuous deployment and monitoring are part of the scope when the project needs them, with the cost spelled out in the proposal. No surprises later.

  3. 02.3

    The code is yours from day one.

    The repository and all access live in your company’s account, with documentation so any team can take over later.

    git remote -vorigin git@github.com:your-company/system.git (fetch)origin git@github.com:your-company/system.git (push)
  4. 02.4

    Scope and timeline in writing before work starts.

    You approve the proposal and see deliveries every one or two weeks in a staging environment.

  5. 02.5

    AI in the workflow, reviewed by a senior.

    Tools like Claude Code speed up the repetitive work; every line is reviewed by someone with 8 years of production experience.

From the first commit all the way to production, the same person who understood your problem.

How it works

  1. 01 · Free project assessment

    You describe the problem in the form and book a 30-minute call about the business, the current system and what needs to change.

    form → 30-min call
  2. 02 · Proposal with scope, timeline and price

    You get in writing what will be delivered, in how many stages and what it costs. For simple projects the proposal is ready in 3 to 5 business days; for larger ones, the timeline is agreed on the call.

    proposal.pdf · scope · stages · price
  3. 03 · Deliveries in short cycles

    Work moves forward in stages you can see running, with access to the repository and the staging environment at all times.

Frequently asked questions

Who will work on my project?

Fernando Alfeld, founder of FerAlfeldDev. He runs the assessment, writes the code and handles the deploy. Nothing is passed on to third parties without you knowing.

What if something unexpected happens mid-project?

The code lives in your company’s repository from the first commit, with documentation and deploy instructions. If another team needs to take over, they pick up where the project is, not from scratch.

Why not hire a bigger agency?

At an agency, the person who sells is rarely the one who builds. Here you talk directly to the senior developer, decisions are faster and the price doesn’t carry the overhead of a large company.

Does FerAlfeldDev know my industry?

The assessment starts with the business: how the company works, who uses the system and where the bottleneck is. In 8 years the systems have spanned very different fields, and anything unfamiliar is studied before the proposal, not during the project.

How much does a project cost?

It depends on the scope. After the assessment you get a written proposal with the price, split into stages, before any work begins. Payment follows the delivered stages.

How long does it take?

It depends on the scope. The timeline for each stage is in the written proposal, and you follow progress with deliveries every one or two weeks.

Is there maintenance after delivery?

Yes. Bug fixes, updates and new features can continue after delivery, agreed separately. If you prefer, the project is handed over with documentation for your team to maintain.

Can you take over a system another company started?

Yes. The assessment includes a review of the existing code to tell you, honestly, whether it’s worth evolving or rewriting parts of it.

Does FerAlfeldDev work with companies outside Brazil?

Yes. The work is remote and can be conducted in English.
