Wesam El-Dawi

I’m a Software Engineer specializing in FinTech and high-scalepayments infrastructure, with a strong focus on AWS-based distributed systems and SRE principles. I build reliable, 24/7 uptime systems for high-volume transaction processing, including automated settlements and local payment integrations.

At Zalando (Payments Infrastructure), I scale AWS-based distributed systems with a primary focus on Site Reliability Engineering and high-availability architecture. I manage and optimize Kubernetes clusters to ensure 24/7 uptime for mission-critical payment services, while enforcing strict PCI-DSS compliance across infrastructure to secure high-volume financial data.

Previously at Zalando (Payments Processing), I developed and maintained Java/Spring Boot microservices inside a high-scale distributed AWS architecture. I engineered core processing logic for local payment methods like Cash on Delivery (COD) and Bank Transfers, optimized PostgreSQL for data integrity and low-latency processing, and improved observability, error-handling, and secure payment data pipelines across distributed AWS regions.
