Isaac Bigsby Trogdon — Portfolio

Enterprise platforms, extended with AI.

15+ years building and maintaining production Drupal/PHP platforms for enterprise clients — the past several spent bringing LLMs, Retrieval-Augmented Generation, and vector search into those same systems as maintained features, not prototypes. Original author and maintainer of three officially released Drupal AI contrib modules, each born from a real production requirement.

Selected Engineering Work

AI Assistant Platform — Drupal + Python Services

Designed and delivered a production AI assistant used across multiple LOOM client projects, spanning the Drupal application layer and a supporting Python service.

  • Drupal-side integration: module architecture, admin configuration, user-facing assistant interfaces, content integration
  • Companion Python service (Flask, OpenAI API) for LLM orchestration, migrated to LangChain to decouple from a single provider
  • Retrieval-Augmented Generation via Qdrant, with a custom REST contract between the Python service and Drupal
  • Ongoing production debugging, retrieval-quality tuning, and maintenance

Semantic Search & Retrieval

Implemented and hardened semantic search backed by vector databases for production use.

  • Worked through embedding choice, indexing strategy, and retrieval quality end to end
  • Extended existing AI implementations to meet production reliability and performance requirements
  • Diagnosed and fixed retrieval results that were plausible but wrong — the failure mode that makes RAG systems hard to ship

Open Source — Drupal AI Ecosystem

Original author and maintainer of three officially released Drupal contrib modules — each one generalized from a real production requirement at LOOM and released back to the community.
