Back-End Developer · Java & Spring Boot · C# · .NET · Building toward global opportunities
Back-End Developer with 4 years in tech, 3 focused on software development. I work daily with C#, .NET, Angular, and SQL Server at Intermidia, and build personal projects using Java 17, Spring Boot 3, and advanced back-end patterns — event sourcing, CQRS, distributed messaging, and AI integrations.
My thesis project FortunAI was an AI-powered personal finance app built with Spring Boot + Google Gemini API, graduated with distinction. Currently pursuing AWS Cloud Practitioner certification and aiming for international opportunities (Australia / remote 🌏).
