Backend software developer at Konto building Java/Spring Boot products, including a cryptocurrency exchange and real-money gaming platform.

Message

At Konto, I develop backend services across products including a cryptocurrency exchange, a real-money gaming platform, a legal-services platform, and an art marketplace. I design domain models, build and secure REST APIs, manage schema evolution, and integrate third-party services.

Before Konto, I developed a C++ airline ticket pricing engine at Sabre and worked on mail server APIs, railway communications, and an Advance Steel plugin. My work has included dynamic ticket-pricing algorithms, modernizing C++ projects, and building software for 3D structural components.
