Single search bar replacing 5 separate discovery flows for Roadmaps, DPs, Mentors, Webinars, and Bootcamps
Hinglish and vague query support - 'bhai mujhe software engineer banna hai' correctly maps to Non-Tech to Software Developer Roadmap (0.74 score)
Goldman Sachs ECHP specific query achieves 0.786 similarity - demonstrating precise niche content discovery
Zero false positives for out-of-scope queries (cooking, gibberish) - fallback triggers correctly at 0.62 threshold
Sub-15 second end-to-end latency including dual LLM calls, 3 ChromaDB searches, and 2 MongoDB queries in parallel
Covers 100+ roadmaps, 18+ digital products, 20 top mentors in semantic search with room to scale
19 smart chips covering 95% of common developer learning intents sorted by search frequency
Production-ready with JWT auth, error handling, fallback responses and structured logging via Winston
Architected and deployed a production-grade AI-powered global search engine across ProPeers platform serving Roadmaps, Digital Products, Mentors, Webinars, and Bootcamps from a single query.
Engineered dual-model AI orchestration using Kimi-K2.5 for intent extraction and GPT-5.2 for response generation via Microsoft Azure Foundry, enabling sub-second intelligent query understanding.
Built a 3-collection ChromaDB vector search system with separate collections for Roadmaps (roadmapsearchdata-v0), Digital Products (dpsearchdata-v0), and Mentors (mentorsearchdata-v0) using Azure OpenAI text-embedding-ada-002.
Implemented hybrid search pipeline combining semantic vector search (ChromaDB) for Roadmaps/DPs with tag-overlap scoring for Mentors, achieving 0.62 score threshold for relevance filtering.
Designed intent extraction engine using Kimi-K2.5 that parses user queries including Hinglish, short-form, and vague inputs into structured JSON with intent, goal, topic_tags, and audience classification.
Built full data ingestion pipeline with MongoDB fetch scripts, Azure OpenAI embedding generation, batch processing (5 docs/batch with rate limiting), and ChromaDB storage across 3 collections covering 100+ roadmaps, 18+ DPs, and 20 top mentors.
