Public marketing page for Kwizie. It includes a view of the product, not an internal or unpublished screen.
Kwizie
Interactive video assessment
Full-stack Developer · AI / EdTech
EdTech product that turns video and other unstructured content into quizzes, answers, and metadata — publicly positioned as in-video assessment, certificates, and embeddable training.
01Problem
Lecture-length video and other unstructured media had to become structured quizzes and metadata through a production client/server path, not hand-authored assessments sitting next to the video.
02Selected contributions
Designed client-side and server-side application architecture and built nested product UI, APIs, and PostgreSQL persistence for Kwizie during the Anadea engagement. The named model pipeline that drafts questions, and who owned it, is not published — application-layer work around that product step is.
- Client-side and server-side application architecture
- Nested product UI with dependent assessment logic
- NestJS APIs and PostgreSQL persistence on AWS
03System context
React product UI calls NestJS APIs; generated quizzes and metadata persist in PostgreSQL on AWS. Quiz generation is a product processing step — the model pipeline and its owner are unpublished.
