Software Engineer (Game, Web & Enterprise Development) | Full-Stack & Data
Java and C# software developer working across game development, enterprise web systems and data.
Since 2023, I've developed and maintained Java applications for Minecraft communities, working with APIs, bytecode manipulation, version compatibility and real-time client-server communication.
I currently contribute to the SICLO ERP at SH Formas e Andaimes, implementing business rules, interfaces and reports with C#, ASP.NET MVC 5/.NET Framework 4.7.2, Entity Framework 6, DevExpress, React, JavaScript and SQL Server.
I have also worked with .NET 9 APIs and use Power BI, DAX and Python/Pandas, with a focus on debugging, data integrity and measurable performance analysis.
Student of Computer Science (Estácio/UNESA) and Cybersecurity (FIAP).
Currently a Full-Stack Development & Data Intern at SH Formas e Andaimes.
Tech educator: helping people improve their CVs, learn programming and develop technical skills.
Contributing to open source.
In love and hate with Java!

- Develop and maintain business functionality in the SICLO ERP using C#, ASP.NET MVC 5/.NET Framework 4.7.2, Entity Framework 6, DevExpress, React, JavaScript and SQL Server; also worked with .NET 9 APIs.
- Implemented delivery-request (SEE) checks that total equipment quantities across linked loads and prevent invalid reductions. Improved Tab/Shift+Tab navigation across three editable production-order (PCP/OP) fields, skipping the action column.
- Fixed access permissions and mobile-number validation (area codes, length and invalid sequences); created a Machine × Equipment grid and restored progress feedback in logistics operations.
- Developed logistics reports and SQL stored procedures with up to eight conditional filters, NULL handling and business-rule validation. Increased incomplete-address test coverage from 3 to 5 scenarios (+66.7%).
- Updated three Power BI reports (Resultados, Agendamento and Dimensionamento de Empilhadeiras), using DAX for financial, commercial and operational indicators. Used SQL for DW/ETL and Python/Pandas to clean and reconcile data.
- Performed simulated A/B benchmarks with up to 250 warm-ups and 1,000 runs per variant, comparing median, p95 and payload sizes. Identified regressions: JSON 4,319 → 5,039 bytes (+16.7%) and HTML 2,080 → 3,768 bytes (+81.2%); these are simulation results, not production performance claims.
- Investigated HTTP/AJAX issues through Service → Controller → View, checked business-rule and referential integrity using 20 records (10 projects × 2 revisions), and documented workflows. Used Git and Azure DevOps for version control and reviews.
- Designed, developed and maintained Java-based applications distributed through CurseForge and Modrinth, with 1.2M+ downloads on published projects and contributions to other projects reporting 10M+ downloads.
- Built modular, object-oriented systems using Java, following clean architecture principles.
- Integrated with complex third-party APIs (Forge, Mixin bytecode manipulation).
- Optimized performance and memory usage for real-time client-server interactions.
- Implemented networking and synchronization logic between client and server.
- Maintained compatibility across game/mod versions, investigated community-reported issues and incorporated user feedback.
- Managed builds and dependencies using Gradle and Git.
