About

Smith Mankar at work, side on, in glasses and a white shirt

I'm Head of Development & Analytics at Sage Sparrows, building production internal tools, automation systems, and AI-powered pipelines. My work spans frontend, backend, and data/AI, always focused on solving real problems for real teams.

My work sits at the intersection of frontend, backend, and data/AI: from real-time platforms used daily by teams to VS Code extensions and ML classification systems, plus storefronts, ad analytics, an on-device model, and 3D and video work.
