Built a LangGraph agent with multi-node query routing across 10+ topic domains, integrating live weather tools, knowledge-base Q&A, and conversation memory. Deployed end-to-end to Railway with a custom domain.

Developed a LangGraph state-machine agent that routes plain-English queries across 10+ topic domains to tool-based weather functions, knowledge-base Q&A, and conversation memory. Designed to reduce hallucinations for regulation-sensitive topics and deployed the agent end to end for production use.

Built a full-stack RAG application that parses resume PDFs, embeds them into a vector store, and retrieves context to score job-match percentages and generate tailored cover letters with GPT-4o-mini. Owned end-to-end LLM product delivery, including the embedding/retrieval pipeline, OpenAI API integration, and production deployment via custom domain.

Developed a full-stack RAG application that parses resume PDFs, embeds content into a vector store, retrieves relevant context, and generates tailored cover letters. Deployed with production-ready structured output using OpenAI APIs and custom domain hosting.

Designed and built a full-stack appointment booking platform with an approval workflow, service menu management, and a mobile-optimized admin dashboard for a live client. Owned end-to-end delivery from requirements and server-side logic to PostgreSQL schema design, Gmail SMTP booking notifications, and deployment on Railway.

Built a full-stack appointment booking platform with an approval workflow and mobile-optimized admin dashboard. Implemented a Django backend with Gmail SMTP and deployed to Railway with a custom domain.

Built and maintained a full-stack appointment booking platform with approval workflow, service menu management, and a mobile-optimized admin dashboard for a live client. Implemented backend data management in PostgreSQL and integrated Gmail SMTP for production notifications, then deployed to Railway with ongoing iteration.

Work and supervise building of aircraft components and parts. Ensure project meets deadline and stay under budget. Organize staff requirements to fulfill orders

Integrated Open-Meteo forecasts to compute multi-variable deer-hunting suitability using custom scoring logic across wind, pressure, temperature, and moon phase. Implemented responsive UI with dark mode and deployed to a custom domain.

Integrated the Open-Meteo API to pull 10-day forecast data and applied multi-variable scoring logic (wind, barometric pressure, temperature, moon phase) to rank best hunting days. Built a responsive dark-mode UI and deployed the app to a custom domain using Railway.

Built a full-stack budget tracker with a Django REST Framework backend and React frontend for expenses and categories. Implemented token-authenticated CRUD endpoints and added pytest coverage with CI/CD deployment on Railway.

Developed a full-stack golf community platform where players log rounds, share course reviews, and track performance. Implemented DRF backend with user authentication and full CRUD APIs, paired with a React frontend, and deployed to Railway.

Developed a golf community platform where users log rounds, share course reviews, and track performance over time. Implemented DRF authentication and full CRUD with a React frontend and deployed the live site.

Built an end-to-end personal finance pipeline from CSV ingestion to SQL-style analysis, visualization, and linear regression forecasting using Streamlit. Demonstrated data processing and modeling using scikit-learn and chart-based UI.

Created an interactive Streamlit dashboard analyzing 39,000+ NTSB aviation incidents with dynamic filtering and drill-down visualizations. Performed large-dataset cleaning, querying, and exploratory plotting with Plotly.

Implemented a RAG pipeline from scratch to learn chunking, embeddings, vector search, and retrieval prior to applying it in production apps. Focused on core retrieval mechanics rather than a follow-along tutorial.

Built a Django-backed arrow-ballistics calculator that determines kinetic energy, momentum, and ethical harvest thresholds for configured setups. Added user save/compare functionality backed by PostgreSQL and deployed on Railway.
