Berk Üstünel
Senior Business Analyst
I've spent 8 years designing processes and products as a business analyst in banking and fintech; I'm into outdoor sports and fitness, and in my free time I read and write about technology, investing, global markets and geopolitics.
About
I graduated in Management Information Systems from Özyeğin University and studied Web Design and Coding at Anadolu University. I began my career at Fibabanka and have continued as a Business Analyst across various projects at Moka United, Odeabank, and now Innovance. I've worked on numerous projects spanning payment systems, digital banking, core banking, open banking, and mobile app integrations. Outside of work, I enjoy outdoor sports and fitness, while also following technology, investing, global markets and geopolitics — occasionally writing about what I learn.
