Service · Custom software development A system built around the way your business works.
Spreadsheets only one person understands, off-the-shelf tools that need workarounds and processes that live in scattered messages are signs that the business has outgrown its tools. Custom software fixes that: the system is designed around your process, not the other way around.
I am a senior full-stack developer based in Curitiba, Brazil, and I build web systems end to end, from understanding the problem to deployment, with a focus on the back end, integrations and making daily work simpler. I work remotely with companies anywhere.
Who it is for
- Companies that run important processes on spreadsheets, email or chat messages.
- Businesses that need a panel for records, orders, scheduling, inventory or reports.
- Teams using several tools that don’t talk to each other and want them integrated.
- Anyone with an existing system that needs to evolve, be fixed or be maintained safely.
What I build
Web systems and admin panels
Records, role-based permissions, reports and dashboards with Laravel and Filament, ready for your team’s daily work.
APIs and integrations
Connections to Google Calendar, WhatsApp, Instagram, payment providers and other systems, with failure handling and retries.
SaaS and digital products
Applications with secure login, multiple users and their own business rules, like Kairo, which tracks work hours and time balance.
Automations
Repetitive tasks become automatic routines: reminders, syncs, data imports and notifications.
Maintenance and evolution
Fixes, improvements and refactoring of existing Laravel systems, without starting over.
Infrastructure and deployment
Linux servers, Docker, SSL, backups, monitoring and automated deploys so the system stays up and stable.
How it works
First conversation
I learn the problem, who will use the system and what needs to happen. No commitment, no jargon.
Scope and proposal
I turn the conversation into a clear scope, with milestones, timeline and cost agreed before starting.
Built in stages
I deliver working parts throughout the project, so you can test early and adjust course when needed.
Launch
I ship the system with automated deploys, backups and monitoring, and follow the first days of use.
Evolution
After delivery, the system can keep receiving improvements and maintenance as the business grows.

FAQ
Custom software
How much does custom software cost?
It depends on the scope: screens, integrations and business rules. After a first conversation I send a proposal with scope, timeline and price agreed upfront.
Read the full answerHow long does it take to build a system?
A lean system can be ready in a few weeks; systems with several integrations take a few months. The timeline is set together with the scope.
Read the full answerCustom software or an off-the-shelf tool?
If an existing tool fits your process, it is usually the better choice. Custom software pays off when the process is specific or the tools don’t integrate.
Read the full answerDo my company’s code and data belong to us?
Yes. The system is built for your company, and the source code and data belong to it, with no lock-in to a closed platform.
Read the full answerDo you work with companies outside Brazil?
Yes. I am based in Curitiba, Brazil, and work remotely with companies anywhere, with online meetings, in English or Portuguese.
