About

Backend Team Lead | 10+ Years of Engineering Excellence | Go & gRPC Specialist | AI-Driven DevelopmentSince beginning my journey in 2015, I have evolved from a deep-dive engineer into a Backend Team Lead focused on building the high-performance infrastructure that powers modern finance and government services. I specialize in architecting scalable distributed systems using Go (Golang) and gRPC, with a proven track record of delivering secure, mission-critical solutions at scale.🚀 Leading with InnovationAs a leader, my mission is to multiply team impact. I don’t just build systems; I build the processes that make engineering teams faster and more reliable. I actively leverage AI and automation to optimize the entire development lifecycle—from accelerating code velocity to enhancing system observability and debugging.💳 FinTech & ScaleMy core expertise lies in the high-stakes world of FinTech. I have architected and led the development of:Secure payment gateways and ISO8583-compliant systems.Complex governmental integrations and tax-authority platforms.Enterprise-grade billing and collection systems used across Egypt.🛠 My Technical Focus:Backend: Go (Golang), gRPC, Protobuf, Microservices.Architecture: Distributed Systems, High-Availability Design, System Optimization.FinTech: Payment Gateways, Secure Integrations, Financial Messaging.AI Integration: AI-Assisted Development, Automated Testing, AI-Driven Monitoring.I am passionate about mentoring the next generation of engineers and continuously exploring how AI can redefine the boundaries of software engineering.Let’s connect to talk about Go, Scalable Architecture, or the future of AI-driven engineering.
