I build custom systems, automations and integrations for companies still relying on spreadsheets, copy-paste and repetitive tasks. I also modernize old systems holding back business growth.
I help companies stop depending on spreadsheets, manual work, and systems that don't talk to each other.
Before thinking about technology, I understand your business's real process: where time is lost, where rework happens, where human error creeps in. Only then do I design the solution: a new system, an automation, an integration between tools you already use, or the modernization of something old that still works but nobody wants to touch anymore.
I bring the same discipline I use on large-scale corporate projects, systems used by thousands of people, with high demands for security and stability. The difference is you talk directly to me, without the overhead of a big project.

Web systems for companies with specific processes that off-the-shelf software doesn't cover.

Does your company still rely on spreadsheets, copy-pasting data or repeating manual tasks? I build solutions that turn these processes into faster, organized digital flows.
03
When two important tools for your business don't talk to each other, I build integrations through APIs and intermediary services, cutting rework and duplicate data.
04
Old systems can still matter to a company, but they can also hold back its growth. I work on gradually modernizing these applications, APIs, integrations and databases, without needing to rebuild everything at once.
05
Migrating a database means hundreds of tables, incompatible data types and a lot of manual validation. It's a risky process if rushed. I'm building a solution to automate much of this work, making migrations safer and more predictable.
Planning to modernize a legacy system?
Talk about your migrationDevelopment and evolution of systems used internally by large organizations, integrating multiple tools and different databases. This is the quality bar I apply to every project, large or small.
Hands-on experience migrating systems from one database technology to another without stopping the business. This experience led to my own research into automating part of that process.
I worked on the layer that connects the Meu Vivo app to several internal and external systems (like Salesforce), making sure the right information reaches the end user quickly, even coming from different sources.
A process management system with secure login and access control. A personal project on GitHub as a practical demo of my work.
A system used by the court to control and organize financial liabilities, information that used to be harder to track and centralize.
A judicial collections system with secure authentication and integration with the court's internal databases, built to handle a high volume of cases without failing.
My solutions make the most sense for companies that:

If your company has a manual process, systems that don't talk to each other, or an old application that needs to evolve, let's talk about the problem before we even discuss technology. Often the solution is simpler than it looks.
