PremierGrad

GMAT-prep SaaS
premiergrad.com

Coaching institutes can't scale proprietary question banks — authoring is slow and quality control is manual. PremierGrad is an invite-only, multi-tenant B2B platform that authors, evaluates and scales a GMAT question bank automatically.

PIPELINE Synthetic data generation with cross-model LLM validation — Claude Sonnet × OpenAI o3 + strict self-critique rubrics
SECURITY Multi-tenant isolation, deployed behind Cloudflare Zero Trust for invite-only institutes
FastAPI Claude API Multi-tenant Cloudflare Zero Trust Python

What-to-Binge

semantic OTT search
what-to-binge.com

Keyword search fails when viewers describe what they feel like watching, not titles. What-to-Binge is a full-stack RAG recommendation engine that lets you discover content in natural language — query by vibe, not metadata.

RAG TMDB content data embedded and indexed in Qdrant; semantic retrieval over natural-language queries
STACK React frontend, FastAPI backend, end-to-end ingestion → embedding → retrieval pipeline
RAG Qdrant FastAPI React TMDB API
