Project Overview

Designed and built a full-scale AI-powered EdTech platform from concept to production. The platform features an AI Coach with multi-tier memory systems, intelligent content generation, and a complete community platform—serving 1,000+ product managers with measurable learning outcomes.

The platform integrates 35+ AI models (Gemini, GPT-4, Claude, DeepSeek, Grok), implements advanced LLM patterns like Chain of Verification and Reflexion, and includes automated content pipelines for blog generation, social media, and personalized coaching.

Key Challenges

  • Building AI systems that maintain context across conversations for personalized coaching.
  • Integrating multiple LLM providers with fallback chains, cost optimization, and quality benchmarking.
  • Creating an intelligent content pipeline that generates PM-specific curriculum at scale.
  • Building a complete community platform with real-time features, replacing third-party solutions.

AI Systems Built

Three-Tier Agent Memory System

Built a production-grade memory system enabling the AI Coach to maintain context across sessions, remember user goals, and provide personalized guidance over time.

  • Working Memory: Current conversation context
  • Short-Term: Recent interactions (7-30 days)
  • Long-Term: Permanent episodic & semantic memory
  • pgvector: Semantic retrieval with 768d embeddings

Technical Implementation

  • Entity extraction (PM-specific NER)
  • Importance scoring for retention
  • Memory compression & summarization
  • Checkpoint/restore sessions
  • 770+ lines production code

Key Learnings

AI Pattern Selection Matters

Different tasks require different LLM patterns. Chain of Verification dramatically improved blog generation reliability, while Reflexion caught issues in submission reviews that single-pass generation missed. The key is matching pattern to problem complexity.

Memory Enables Personalization

Building a proper memory system transformed the AI Coach from a chatbot into a genuine coaching experience. Users report that the coach "remembers" their goals and provides contextually relevant guidance—this is entirely due to the episodic/semantic memory architecture.
