Hi, I’m Ahmed Mohammed Ali. I’m a Senior Backend Developer with 6+ years building cloud-native, high-throughput FinTech and enterprise systems. I deliver secure APIs and integrations (Node.js, Spring Boot, ASP.NET Core, MuleSoft) that handle 1k+ transactions/min and 10k+ active users, while boosting latency and reliability through observability-driven tuning and CI/CD automation. I’m seeking senior backend or platform roles (remote or relocation). I value collaboration, clean architectures, and continuous learning, and I enjoy turning complex requirements into robust, scalable systems.…Hi, I’m Ahmed Mohammed Ali.
