Hi, I'm
Ilham Jaya Saputra.
I study Statistics at Universitas Airlangga and build data solutions on the side, from predictive models and data pipelines to analytics dashboards.
A little bit about who I am
Stats nerd by day, AI builder by night. Here's the short version.
Ilham Jaya Saputra
I am a Statistics undergraduate at Universitas Airlangga with a strong focus on data analysis, machine learning, and statistical modeling. I have a growth mindset and enjoy exploring data-driven technologies. Highly proficient in Python, R, and Excel.
Beyond the classroom, I have led survey teams at national companies, coordinated a university science community, and competed in national data competitions while earning several awards.
