Senior AI Development

$35/hr Starting at $5K

I provide expert Python and AI development services focused on building lightweight, high-impact tools for real-world use. My work helps businesses and consulting firms automate workflows, extract insights from unstructured data and deploy AI assistants that add real value.

Whether you need a quick prototype or a production-ready integration, I bring a structured, results-driven approach from discovery to deployment. I work closely with clients to understand their goals and deliver clean, well-documented solutions that are easy to maintain and scale.

I can help:

  • LLM-powered AI assistants using LangChain, LlamaIndex, OpenAI, Claude, or open-source models

  • Retrieval-augmented generation (RAG) pipelines connected to your internal documents

  • Custom automations that reduce manual effort using Python scripts and APIs

  • Integration of AI features into Django or FastAPI applications

  • End-to-end prompt engineering and evaluation to improve output reliability

  • Unstructured data processing from PDFs, CSVs, text, and web scraping

  • Deployment-ready APIs, bots, and internal tools for client-facing or in-house use


I use tools and technologies:

  • Languages: Python, SQL, JavaScript

  • AI/LLM Stack: OpenAI, Claude, LangChain, LlamaIndex, Hugging Face, GPT-4, vector search

  • Frameworks: Django, FastAPI, Flask

  • Data Tools: Pandas, NumPy, spaCy, PyMuPDF

  • Cloud and DevOps: Docker, AWS, Azure, GitHub Actions

  • Others: Postman, Jupyter, Notion, MS Teams, Slack bots

    BEAT CANCER says,

    We had an outstanding experience working with this team on the development of our AI bot and virtual assistant. From the very beginning, they demonstrated a deep understanding of both the technical side of AI integration and the user experience required to make it truly effective on a live website. They didn’t just build a generic chatbot, they took the time to understand our mission, our audience, and the specific types of interactions we needed. The result is an intelligent, responsive system that feels natural, provides real value to our visitors, and significantly improves engagement and efficiency. What impressed us most was their ability to translate complex requirements into a seamless, user-friendly solution. The bot is fast, accurate, and continues to learn and improve. On top of that, their communication, responsiveness, and willingness to refine details made the entire process smooth and professional. If you’re looking for someone who can build a high-quality AI-driven assistant that actually performs, not just looks good, we highly recommend their services.

    Doug was INCREDIBLE to work with! He was very timely responding to my emails, did exactly what I asked without having to go back and forth, was very knowledgeable about what he was doing, professional, and completed the job earlier than I expected! I highly recommend Doug and would definitely hire him again! ~Wendy
