About this gig

I am a Senior AI Engineer backed by a specialized team of software architects. We help startups and businesses leverage Large Language Models (LLMs), vector databases, and custom Python frameworks to turn complex data into actionable AI solutions.


How We Solve Common AI Challenges:

  • LLM Hallucinations & Inaccurate Outputs: We build production-grade Retrieval-Augmented Generation (RAG) pipelines using LangChain, LlamaIndex, and vector databases (Pinecone, ChromaDB, Qdrant) for precise, hallucination-free responses based on your proprietary data.
  • Disconnected Data & Workflows: We create autonomous AI agents and custom REST APIs that connect LLMs directly to your existing databases, web apps, or enterprise CRMs.
  • High API Costs & Latency: We optimize prompt engineering, implement response caching, and fine-tune open-source models (Llama 3, Mistral) to reduce compute overhead.


Technical Capabilities:

  • LLMs & Frameworks: OpenAI GPT-4, Anthropic Claude, Llama 3, LangChain, LlamaIndex
  • Vector DBs & Memory: Pinecone, Chroma, Weaviate, Qdrant, FAISS
  • Backend & APIs: Python, FastAPI, Flask, Docker, AWS/GCP
