Summary

AI Engineer with a background in professional aviation, enterprise data analysis, and autonomous systems development. Holds a CS50p certificate from Harvard/edX with a year of sustained open-source AI contributions on GitHub. In February 2026, designed, built, containerized, and deployed a production autonomous AI agent system in a single development session — and subsequently submitted the extracted modular framework to Anthropic's open skills repository (PR #444, anthropics/skills). Brings a domain-rare combination: aerospace-level systems rigor, production AI deployment experience, and a deeply held belief that well-built systems make people's work better. Seeking an AI Engineer role where that combination can contribute meaningfully.

AURELION Modular AI Suite — Submitted to Anthropic Skills Repository
February 2026
github.com/chase-key  ·  PR: anthropics/skills #444 — feat: add AURELION skill suite

Designed and published a modular, open-source cognitive AI architecture spanning six interoperable repositories, each independently deployable and composable. Submitted for inclusion in Anthropic's public skills library; all modules met Anthropic's standards for structure, documentation, and reusability.

Memoria Engine — Production Autonomous AI Agent
February 2026
Live: memoria-engine.fly.dev  ·  Stack: Python · FastAPI · OpenAI API · ChromaDB · Docker · fly.io  ·  Concept to production in under five hours
  • Engineered lazy indexing to reduce application cold-start from 30 seconds to under 2 seconds
  • Implemented three-tier character resolution fallback system maintaining zero-downtime across naming inconsistencies
  • Hardened cross-platform encoding (Windows development → Linux production container) across 15+ I/O operations

Enterprise Data Investigation — Multi-Year Root-Cause Analysis
January 2026
LexisNexis / RELX Group

Led a structured, multi-phase investigation into a longitudinal data anomaly affecting court record volume accuracy across multiple jurisdictions. Applied custom SQL (window functions, CTEs, cross-feed aggregation) to trace failure to a parser logic condition causing systematic record exclusion. Findings validated by Engineering; corrective fix deployed. Investigation methodology adopted as the team's standard framework.

Knowledge Systems Architecture — AAAI Enterprise Framework
Jan–Feb 2026

Designed a five-layer knowledge architecture: 35+ interconnected documents, 15,000+ lines of structured content, Python-powered search library, semantic knowledge graph (JSON). Includes 4-week analyst training curriculum, investigation decision tree, enterprise data governance framework, and workforce capacity model — all piloted organizationally at zero additional budget.

Profile

I am genuinely grateful for every opportunity that has led here. My path has not been linear — aviation, data analysis, and now AI engineering — but each chapter has built something the next one needed. Aviation gave me systems thinking and a deep respect for what happens when precision fails. Data analysis grounded that thinking in real-world complexity: multi-year anomalies, organizational scale, and the responsibility of getting it right. AI development gave me a new medium to build things that actually help people do their work better. I believe the most valuable thing an engineer can do is understand a system well enough to make it trustworthy. That belief applies equally to flight systems, data pipelines, and autonomous AI agents. I bring it to every problem I touch.
