Arpit Gupta

I’m a Software Engineer with 7+ years of experience building scalable backend systems and high-volume transaction platforms. I currently work as an SDE 3 at PayPal, where I design and develop payment settlement systems that process millions of transactions daily. My work includes implementing features like Acquirer Reference Number (ARN) tracking, enhancing global payment capabilities, and improving settlement microservices for scalability and efficiency.

I specialize in Java, Spring Boot, microservices architecture, and cloud technologies, with hands-on experience across AWS, Kubernetes, Kafka, and distributed systems. Having worked with product companies like PayPal, Xactly, Genpact, and Oracle Financial Services, I enjoy solving complex engineering problems and building reliable, high-performance systems.
