01 / ABOUT
Engineering with purpose.
My interests lie at the intersection of Artificial Intelligence and Web Engineering.
I enjoy turning complex technical concepts into practical systems — from machine learning models and NLP applications to retrieval-augmented generation systems and backend APIs.
Alongside my studies, I have experience teaching AI/ML and software engineering concepts, mentoring students, and building practical projects using Python, Java, Spring Boot and modern AI tooling.
