Software Engineer @ RS Software

I'm a passionate software engineer with over 4 years of experience building scalable backend systems and payment solutions. Currently, I'm working at RS Software, where I architect and develop high-performance payment processing systems that handle thousands of transactions per second.

My expertise lies in Java, Spring Boot, microservices architecture, and distributed systems. I thrive on solving complex problems and building solutions that make a real impact. When I'm not coding, you'll find me exploring new technologies, contributing to open source, or sharing my knowledge through tech blogs.
