What I'm looking for

I am looking for a role that fosters innovation and offers opportunities for growth in a collaborative environment.

I am a Senior Java Developer with extensive experience in building and optimizing scalable payment systems. Currently, I work at Paysend, where I have successfully launched and optimized a multi-currency accounting and card management platform from scratch using Java microservices. My role involves seamless migration from legacy systems to modern architectures, ensuring compliance and enhancing financial inclusion for underbanked populations.

Previously, I served as a Senior Fullstack Developer at Evotor, where I established development processes and designed scalable account management systems. My work included real-time receipt tracking and integration with various APIs, which significantly improved operational efficiency. I have a strong foundation in Java and various frameworks, and I am passionate about leveraging technology to solve complex problems.
