Senior🎓
Top SchoolJeffrey Effendy is a pragmatic software engineer with 11 years of experience building data-rich, production-grade systems across startups and large tech companies, currently at Meta. His background spans full-stack web development, scalable data engineering and machine learning-driven marketing solutions from roles at Grab and Dentsu Aegis, where he moved heavyweight data platforms toward serverless architectures. Comfortable across Java, JavaScript/TypeScript stacks and visualization tooling, he has delivered everything from 3D visualizers connected to ROS to attribution platforms and automated ad-copy prototypes. Based in Stony Stratford, he combines a developer-first mentality—“I will ship my machine”—with a track record of turning research prototypes into robust, cost-conscious production services.
