A management platform for a private country club, centralizing membership administration, dues and billing, facility reservations, and member self-service into a single system.

• Digitized membership records, account status, and dues/billing workflows to replace manual and legacy processes.
• Built reservation and facility-management flows so members and staff could coordinate bookings and services.
• Automated recurring statements and document/report generation (PDF/Excel) for billing and administration.
• Integrated secure online payment processing for member dues and transactions.

A Retrieval-Augmented Generation pipeline that returns relevant medical codes from clinical or administrative documentation.

• Combined semantic/vector search with keyword-based retrieval to improve code-matching accuracy over naive search.
• Ingests documentation, chunks text, generates embeddings, retrieves candidate codes, and returns ranked results.
• Implemented as a practical backend workflow for medical documentation analysis and code-lookup automation.
