What I'm looking for

"I am seeking a Data Analyst / Python Developer role where I can leverage machine learning to solve complex business challenges. I aim to bridge the gap between backend engineering and business intelligence by building robust data pipelines and delivering intuitive, actionable dashboards."

I’m a Data Analyst intern who builds systems that turn transaction data into actionable fraud detection. At Phoenix Software 3000, I developed an automated approach for identifying suspicious mobile payment activity and improved model-ready data through preprocessing, class balancing, and exploratory data analysis (EDA).

I focus on clarity as much as performance: I designed dashboards and interactive reports that translate analytical results into stakeholder-ready insights. My work emphasizes reducing prediction bias and making findings understandable and usable.

Before deepening into data science, I strengthened my product instincts through frontend work. As a Frontend Developer Intern, I redesigned a banking management web application’s user interface to improve visualization of operational data, and I optimized component structure using reusable, scalable patterns.

I also bring a UX/UI mindset from my internship experience, designing user-centered web and mobile interfaces to improve digital workflows. I’ve translated technical information into visual materials using Powtoon and supported project-based learning as a volunteer teacher for web development.
