What I'm looking for

I’m looking to transition into data science and contribute to impactful projects. I want to apply machine learning and statistical modeling, using strong engineering fundamentals to build reliable, production-ready data products.

I’m a full-stack developer with 7+ years of experience building user interfaces, applications, and backend systems. I’ve led backend development for an AI fashion studio—building data structures and APIs, improving data loading by 25%, and supporting growth to 100,000 users while keeping interactions smooth.

At AXA Life Insurance, I created an insurance claims system that reduced processing time by 40% and achieved a 98% user satisfaction rate for data entry. I also focus on quality and reliability—adding tests and reusable components to reduce UI errors and improve coverage—and I’m currently pursuing an MSc in Data Science to apply machine learning and statistical modeling to real, impactful projects.
