About Us

👨‍💻Programming & Mathematical Excellence

Marko Šinko is a Croatian developer with exceptional mathematical and coding abilities, combining academic rigor with practical innovation. His expertise spans blockchain GameFi development, Unity-based multiplayer systems, and semantic web technologies - skills that directly contribute to the sophisticated calculator algorithms and user experience on aimathcalculator.com.

Academic Foundation & Technical Grounding

Marko completed his four-year Computer Science program at the Faculty of Organization & Informatics (FOI), University of Zagreb, specializing in business information technologies. His 2013 bachelor thesis "DBpedia u primjeni" (DBpedia in practice) demonstrated early interest in semantic web data and API design - expertise directly applied to our calculator's data structure and mathematical knowledge representation.

After graduation, he joined Kupi key d.o.o., where he developed full-stack skills in PHP, JavaScript, and Unity that later translated into the robust, cross-platform architecture powering our 500+ mathematical tools.

Innovation Leadership & Recognition

In 2022, Marko co-founded DogeRift, a groundbreaking 2.5D/3D play-to-earn metaverse running on Neo N3 blockchain. The project won "Best NFT/Metaverse Project" at Neo's Polaris Launchpad hackathon and the Planathon Award, demonstrating his ability to build complex, award-winning mathematical and algorithmic systems.

His work on Unity multiplayer systems with on-chain smart contracts showcases the same precision and mathematical thinking that ensures every calculator on our platform delivers accurate, reliable results.

🚀Entrepreneurial Prodigy & Visionary Leader

Jurica Šinko is a remarkable Croatian entrepreneur who became the youngest registered company director in Croatia at just 18 years old. His mathematical precision and business acumen drove him to earn his first million HRK (€130k) before age 21, establishing him as "Croatia's youngest internet millionaire" and the perfect co-founder for a comprehensive mathematical platform.

Bootstrap Success & Digital Innovation

While still a high school student at Varaždin's Electromechanical School, Jurica spotted an opportunity in digital game key resale and founded Kupi Key d.o.o. in March 2012. By 2014, the company had cleared over HRK 1 million in net profit, and by 2015 logged revenues of HRK 7.4 million (€1M), selling over 300,000 game copies worldwide.

His success came from mathematical analysis of market gaps, precise pricing algorithms, and systematic reinvestment - the same analytical mindset that ensures our calculator platform serves accurate, comprehensive mathematical solutions.

Diversified Gaming & Media Empire

Through Just1337 Studio (2015-2017), Jurica co-published 18 indie game titles, earning "mostly positive" Steam reviews and demonstrating his commitment to quality user experiences. His latest venture, EGamer.com gaming media portal, positions Kupi Key as a comprehensive entertainment and educational technology company.

Jurica's philosophy of reinvesting profits into development teams rather than personal luxury reflects his commitment to building lasting educational tools - which is why aimathcalculator.com offers 500+ professional-grade calculators completely free.
