Log Clustering and Triage Agent over MCP
A pipeline that parses messy multi-format logs into severity-aware clusters, exposes the clustered views as read-only MCP tools, and lets a LangGraph agent answer natural-language questions like 'only errors in payments' or 'show me the raw lines for cluster 7' in seconds.

- A day to adapt the reference Colab to your log format

Scheduled Log-Anomaly Sentinel with Vector Search
A recurring job that embeds a baseline of healthy log lines into Qdrant, then on each run flags lines whose nearest-neighbor distance is far from the baseline as anomalies, summarizes the clusters with an LLM, and notifies the on-call channel before the anomaly becomes an incident.
- Build time
- A day for a working sentinel on one log stream

Hybrid-Search Customer Support Chatbot with LangGraph and Qdrant
A knowledge-base Q&A chatbot that blends dense semantic search with sparse keyword matching in Qdrant, orchestrated by LangGraph, so support answers stay grounded in your real docs and stop hallucinating.
- Build time
- Half a day for a prototype
- Stack
- LangChain + LangGraph + Qdrant + OpenAI Platform
Turn a Documentation Site into a Support Agent with Firecrawl and LangGraph
Crawl a docs site or help center into clean markdown with Firecrawl, embed it into a vector store, and serve a LangGraph ReAct agent that answers product questions with citations and self-refines its retrieval.
- Build time
- Half a day for a prototype
- Stack
- Firecrawl + LangChain + LangGraph + Qdrant
Brand-Aware Content Generator with RAG
A RAG content platform that embeds your company's own documents into Qdrant, retrieves the most relevant context by semantic search, and feeds it to an LLM so every generated social post or article is grounded in your real messaging.
- Build time
- A day for the end-to-end pipeline
- Stack
- Qdrant + Nebius | Token Factory + Llama 3.3 70B Instruct + Qwen3 Embedding
Document Agents over Manuals and FAQs with LlamaIndex
Parse complex product manuals, FAQs, and policies with LlamaParse, index them, and serve document agents that answer customer questions with citations, traceability, and confidence — deflecting repetitive tickets.
- Build time
- Half a day to a day for a prototype
- Stack
- LlamaIndex + LlamaParse + OpenAI Platform
Chat With Your Codebase Using LlamaIndex RAG
Index a GitHub repository with LlamaIndex, store embeddings in a vector database, and answer natural-language questions about the code with citations back to the exact files.
- Build time
- 1-2 hours for a prototype
- Stack
- LlamaIndex + LlamaHub (LlamaIndex tools) + Qdrant Cloud Free Tier + GitHub repository + Google AI Studio / Gemini API
Second-Brain Notes Assistant (RAG over your vault)
Ask questions in natural language across your Obsidian or Notion notes. A retrieval-augmented assistant indexes your vault into a vector store and answers with citations back to the source note.

- Qdrant Cloud Free Tier + Mistral AI (La Plateforme) + Jina AI Search Foundation (Embeddings + Reranker)
Parse Complex PDF Manuals into a Qdrant Hybrid-Search Knowledge Base
A document-parsing pipeline that turns messy PDF manuals with tables and figures into clean markdown with LlamaParse, embeds it, and stores dense plus sparse vectors in Qdrant for hybrid-search retrieval.
- Build time
- 2-3 hours
- Stack
- LlamaIndex + LlamaParse | LlamaCloud + Qdrant Cloud + Jina AI Embeddings + Hugging Face Inference
Crawl a Documentation Site into an Upstash Vector RAG Index
A crawl-to-structure-to-store pipeline that recursively crawls an entire docs site into clean markdown with Firecrawl, chunks it, and upserts embeddings into Upstash Vector for serverless retrieval.
- Build time
- 1-2 hours
- Stack
- Firecrawl + Upstash | Vector + OpenAI
Incrementally Sync a Source into a pgvector Index Without Re-Embedding
A scheduled ETL sync that re-ingests a changing document source into a Supabase pgvector index using LangChain's record manager, so only new or changed chunks are embedded and stale ones are cleaned up.
- Build time
- 2-3 hours
- Stack
- LangChain + Supabase | Postgres + OpenAI
Live-Docs Migration Assistant with Firecrawl and Qdrant
Scrape a framework's current docs with Firecrawl, index them in Qdrant, and run a LangGraph ReAct agent that answers migration questions with up-to-date, cited syntax instead of stale LLM memory.
- Build time
- Half a day for a prototype
- Stack
- Firecrawl + Qdrant Cloud Free Tier + LangChain + Jina AI Search Foundation (Embeddings + Reranker) + DeepSeek Platform
Private Web Research Agent with Self-Hosted SearXNG
A research agent whose web-search tool is a self-hosted SearXNG metasearch engine instead of a metered commercial API — all search traffic stays local, no per-query billing, and you control which engines are queried, paired with Firecrawl for clean extraction.
- Build time
- Half a day including Docker setup
