About

Full Stack Developer with 4+ years of experience in enterprise systems, passionate about building scalable and impactful software products. Currently at TS Solutions, I design and maintain full-stack applications using AngularJS, C#, and PostgreSQL.

A lifelong learner driven by curiosity, I began coding at age 11 and now pursue a Bachelor's in Information Systems at Instituto Federal Catarinense, where I explore the intersection of technology, language, and leadership.

I’ve led award-winning projects, such as 1st place at NASA Space Apps and IFC Hackathon and contribute to open-source communities. One of my recent projects is a spaced repetition platform for Mandarin learners, combining adaptive learning with language acquisition.

In the AI space, I work with tools like Ollama, LangChain, and the Qdrant vector database to develop Retrieval-Augmented Generation (RAG) systems that deliver intelligent, context-aware responses based on personalized tax data. These solutions help users calculate their own taxes more easily, intuitively, and transparently by providing fast access to complex financial records and compliance documents.
