United Arab EmiratesWhat I'm looking for
I’m a Software Engineer with 5.5 years of experience building and operating production-grade platforms. I currently serve as SDE-3 at Pay10 Global, where I’m a core member of the engineering team building Pay10’s payment and banking platform from scratch.
At Pay10, I designed and implemented integrations with multiple regional banks under the CBUAE Open Finance framework, collaborating with teams across MENA and APAC to support regional compliance and live go-live rollouts. I also monitored production during launch phases, resolved real-time transaction issues, and helped ensure high system availability while working on a developer portal and reseller/deployment workflows.
Previously, I led high-impact backend ownership and reliability work at PayPal India and E&Y (American Express), including a user account settings module for 1M+ users, fraud mitigation using logistic regression and anomaly checks, and migration of sensitive financial data with strong security compliance. Earlier in my career at Boeing, I developed cloud-based emission and fuel dashboards, built REST APIs with Spring Boot and React integration, and implemented real-time streaming with Kafka—containerizing services with Docker and deploying on Kubernetes for scalable architecture.
