Jack Deng
Senior Software Engineer | Backend & Data Systems
Hi, I'm Jack — a Software Engineer based in California, focused on designing reliable enterprise data systems and full-stack applications. I bridge business operations and technical infrastructure through robust backend architectures and scalable data pipelines.
This site is my public workspace: engineering notes, integration patterns, and tools I build along the way. It runs on Next.js + Payload CMS with a Supabase PostgreSQL backend.
Outside of work I'm probably debugging a flow, reading systems-design docs, or figuring out why the ETL ran 3 seconds slower than yesterday.
