About

Full-Stack developer. My main stack is Java and Spring on the backend, React on the front. I also wander into Computer Vision and Game Development.

I get the most out of everything I build and help people along the way. Clear communication, real commitment, quick to learn whatever the project needs.

Where I've been

  1. 2026Now

    Université de Moncton

    Researcher · Aug 2026 — Now

    • Python
    • PyTorch
    • PennyLane
    • Vision Transformers
    • CNNs
    • Quantum ML

    Mitacs Globalink research internship at the PRIME lab in Moncton, Canada, on the project Quantum Machine Learning and Deep Learning in Oncology, supervised by Prof. Moulay Akhloufi. My focus is cervical cancer: I classify Pap smear images from the CRIC dataset with CNNs and Vision Transformers, then test quantum kernel-based classifiers and hybrid DL-QML pipelines to compare them against the classical baselines.

    Intern → Junior Full-Stack Developer · Mar 2025 — Aug 2026

    • Java
    • Spring Boot
    • Node.js
    • React
    • SonarQube
    • BMAD

    Joined as a Software Development Intern and was promoted to Junior Full-Stack Developer in January 2026. As an intern I worked with Java (Spring Boot) on the backend and React on the frontend, using Gitflow, Docker and AWS. As a junior I moved to Node.js on the BFF and React on the frontend, got much more comfortable with code quality tooling like SonarQube, mutation testing and component tests, and learned to work with BMAD, an agent-driven workflow built on custom Claude agents.
