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

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
