🚀 Featured Projects

Retrieval-Augmented Generation (RAG) agent resolving domain-specific customer support queries with zero hallucination.

  • RAG & LangChain Pipeline: Built with FastAPI, ChromaDB, and Groq's Llama 3.3 to fetch and deliver context-bounded responses.
  • Scraping & Indexing: Created an ETL pipeline using Playwright for web scraping and LangChain for text chunking, semantically indexing 300+ vector records into ChromaDB.

Python FastAPI LangChain ChromaDB Playwright


Tag-based weakness-scoring recommendation engine ingesting 3,000+ problems to target user skill gaps.

  • GraphQL & Caching: Real-time profile ingest via LeetCode GraphQL API, backed by a two-tier caching layer.
  • Testing & Auth: Secured via Pydantic validation & Supabase Auth; automated CI/CD pipeline enforcing code quality via pytest and GitHub Actions.

Python GraphQL Pydantic pytest GitHub Actions


Transforms long-form articles into platform-ready outputs for Twitter, LinkedIn, Instagram, Newsletter & Medium in seconds.

  • Groq LLaMA 3.3 70B: Zero-shot learning system for multi-channel copy generation.
  • Security & Data: Full-stack FastAPI backend with JWT Auth (bcrypt hashing, 24h expiration) and PostgreSQL on Supabase.

Python FastAPI LLaMA 3.3 PostgreSQL Supabase


AST parsing and graph-based dependency mapping engine automating legacy code documentation and anti-pattern detection.

  • Dependency Graphing: Mapped 10,000+ relationships across 7+ codebases using NetworkX & Graphviz, reducing developer onboarding time by 40%.
  • Anti-Pattern Engine: Detects 6+ code smells (dead code, circular dependencies, magic numbers) rendered on an interactive Streamlit dashboard with Plotly heatmaps.
