Hi, I’m Otis Powell

Software Engineer and Data Analyst building production dashboards, AI-assisted tools, and data pipelines, with a focus on energy and decision support.

What I Do

  • Build production-grade web apps and dashboards (Streamlit + Plotly)
  • Develop data pipelines and ETL workflows (CSV/Parquet, validation, monitoring)
  • Deploy containerized apps with Docker on cloud infrastructure (AWS EC2)
  • Integrate LLMs and RAG systems for automation and knowledge retrieval

Live Applications (Public Demos)

These are client-style applications with private source repos.

Tech Stack

  • Languages: Python, JavaScript, SQL (basics)
  • Data & ML: Pandas, NumPy, scikit-learn
  • Visualization: Streamlit, Plotly, Matplotlib, Folium (geospatial)
  • AI: LLM integrations (OpenAI, Anthropic, Google GenAI, Groq), prompt engineering, function calling
  • RAG: Pinecone (vector search), embeddings, retrieval workflows
  • Cloud & DevOps: AWS (EC2, S3), Docker, Git, CI/CD basics
  • Automation: n8n workflow orchestration, API integrations

Selected Work (Public Repos)

  • TravelTiming (Streamlit + Plotly + APIs): interactive travel recommendation app
  • Powdery Mildew Detection (ML + Streamlit): image classification dashboard
  • Django Travel Blog: full-stack app with authentication and PostgreSQL support

Current Focus

Building scalable AI-assisted software systems, stronger deployment patterns, and reusable data tooling for real-world analytics products.
