## About

```text
At G3Deon, I moved from intern to developer while building a demo ERP system in React, TypeScript, and HeroUI with Supabase as its backend. I also designed the database model and mapped business processes with flowcharts.

At NEORIS, I performed functional and API testing for critical banking flows for Banco Popular’s Azul app. I designed and ran test cases, documented defects, and worked directly with the client to validate features.

For my Facturify project, I built a Java desktop invoicing system with Swing and MySQL, then redesigned it in C# and ASP.NET Core with a layered architecture. I use SOLID principles and Factory and Singleton patterns, and configured GitHub Actions to run builds and NUnit tests on each push.

I’m a software development graduate of ITLA, with practical experience in web development, QA, and customer support. I’m looking for a technology role in development, QA, or support where I can contribute and grow alongside a senior team.
