Mohamed Awnallah is a data engineer with five years of hands-on experience building scalable data platforms and pipelines that process terabytes of telemetry and measurement data. He blends Python, SQL, Spark, Kafka and AWS with strong software engineering practices—CI/CD, testing automation, and FastAPI—to deliver production-grade solutions across internet infrastructure, security, retail and healthcare domains. Mohamed has a track record of high-impact open-source contributions, from improving Apache Beam’s SDK transforms and ML integrations to hardening Karmada’s CLI and boosting test coverage for CNCF projects. At Lightning Labs he dramatically accelerated Bitcoin wallet sync times (15 minutes to 30 seconds) and fixed a long-standing multi-system sync bug, demonstrating both deep systems thinking and performance-first pragmatism. He also detected a real-world Brazil internet outage during his IHR work and built dynamic visualizations and an alarms correlation system that improved global network situational awareness. An active community contributor and content creator, he combines research-grade curiosity with production experience and a talent for turning complex distributed data into actionable insights.
