About

Hi, I’m Ivan! I am currently pursuing my Master’s degree in Business Mathematics at the Technical University of Berlin. My studies focus on optimization, finance mathematics, machine learning, game theory, and data analysis, blending mathematical theory with practical applications. I am adaptable, fast-learning, and skilled in bridging technical expertise with practical implementation. My strengths include analytical problem-solving, cross-functional collaboration and process optimization. Beyond finance, I have a growing interest and experience in product development, data analytics, and UX/UI design, where I enjoy driving efficiency through innovation. Currently, I work as a Finance Working Student at Moss, where I collaborate closely with Product, Operations, and other teams on initiatives that merge financial insights with technical problem-solving. My work has allowed me to develop a well-rounded skill set that spans finance, data-driven decision-making, and product-focused projects. My previous experience includes internships at Deutsche Bank and Solaris, which sparkled my enthusiasm for finance and maths, as well as some other shorter positions across other industries, where I just expanded my horizons out of interest. I’m always eager to take on new challenges and expand my expertise in mathematics, finance and technology — and other things. And other things, which were not included in the previous “And other things”. I enjoy things. Hit me up if you’d like to talk about things ;)
