Software development
Have an idea but not sure where to begin? I can help turn it into a working solution, building features and structuring the system behind them.
SOFTWARE DEVELOPMENT
Your idea deserves to come to life.
New software, improvements to existing systems, and solutions to everyday problems. Whether you’re starting something new or building on what you already have, let’s talk about what you need.
From our first conversation to delivery.
How can I help?
Maybe you know exactly what you want to build. Or maybe something in your system simply isn’t working as expected. We can start there.
Fixes and improvements
Does an error keep getting in the way? Or does your system need to grow? I can investigate the cause and work on practical improvements.
Testing changes with confidence
When you change one part of a system, will everything else still work? Tests help catch problems before they affect users.
Documentation that makes things easier
Clear documentation helps the next person understand, use, and maintain a system without guessing how it works.
Projects that tell the story
I like showing how things work in practice. These projects show the problems software can solve and the decisions behind each solution.
ORDER MANAGEMENT
Order Management API
Imagine managing customers, products, and orders in one place. This project shows how to organize information, check if an order can be placed, and avoid common calculation errors.
Open the Order Management API project page →TAX CALCULATION
FiscalCore API
Tax calculations and access to sensitive information deserve care. This project combines organized records, calculations, and controlled access.

Tell me what you need, and we’ll plan the next steps together: what gets built, the cost, and the timeline.
Talk
We discuss your idea, your challenges, and what success would look like.
Agree on a plan
We agree on deliverables, schedule, price, and expectations.
Build
I develop the agreed solution and keep you informed of progress.
Deliver
We review the deliverables and leave the information you need to maintain or grow the project.
I’m a software developer who enjoys getting to the bottom of a problem. Sometimes a solution starts with a new idea; sometimes with a simple question: why isn’t this working?
I worked at Compass UOL, where I developed my programming and teamwork skills, and at PicPay, supporting systems involved in payment authorization. Those experiences taught me why the details matter.
Today, I help build features, investigate bugs, test changes, and organize documentation. I mainly work with Java and Spring Boot, but you don’t need to know these technologies to tell me about your idea.
I like agreeing on expectations early and keeping communication open. If you already know the details, great. If not, a conversation is a good place to start.
Questions before getting started?
Do I need a complete plan?
No. Bring an idea, a difficulty, or just a question. We can figure out what makes sense together.
Can you improve an existing system?
Yes, after reviewing the system and technologies involved. We can discuss specific bugs or improvements.
Can I hire you for one specific task?
Yes. We can agree on a focused task such as fixing a bug, writing tests, or improving documentation.
How are prices and timelines defined?
We discuss your needs first. Then I prepare a quote and we agree on the scope and timeline.
Will I receive progress updates?
Yes. We agree on how to communicate so you can follow progress and ask questions.
Let’s talk about your idea?
Tell me what you’d like to build, fix, or improve. You don’t need a technical background or a complete plan.
