Joseph Davis Chamdani
Informatics @ University of Washington
I build AI and data products, and I ship them.
I sit between product and engineering: research what people actually do, build it, then test it until it survives someone else using it.
About
I build technology that augments human judgment instead of replacing it. Trust in an AI system does not come from a high confidence score. It comes from clear boundaries, honest limits, and behavior people can predict.
Originally from Jakarta, Indonesia. Moved to Seattle at 15, accelerated through a high school completion program at Bellevue College, and entered UW's Informatics program as a junior.
Most recently an AI Product Intern at Whitespace Solutions, shipping full-stack features and semantic search on an AI sales-training platform, after building AI automation for cybersecurity at Sector and leading BC Tech Club through BC Hacks 2024. The through line is AI ethics, human-computer interaction, and tools people actually use.

AI Product Intern
Whitespace Solutions | Jul 2026 - Sep 2026 | Jakarta, Indonesia
Built and shipped features end to end on a live AI sales-training platform across the database, the backend API and the React front end. Built semantic search for the product's knowledge library on its shared embedding and vector layer, with hybrid ranking, a relevance floor and an AI-label check. Fixed a vector-store bug that silently lost writes and a failure that made chat answer 'no knowledge' on a full library. Drove competitive analysis of 4 US and APAC sales-enablement platforms that informed a company-wide repositioning, and ran pre-launch QA that surfaced 30+ defects ahead of the first live enterprise deployment.

Built AI tools to accelerate penetration testing and cybersecurity workflows. Developed automated threat detection systems. Trained AI models on XOps data, improving efficiency by 20% over manual regex methods.
