Profile
I work across enterprise software architecture, data platforms, AI-enabled systems, cloud architecture, mainframe and distributed systems, and applied computer science research. My background combines hands-on software engineering, architecture leadership, platform modernization, enterprise integration, governance, and technical mentoring.
My work centers on designing durable technology foundations: systems, models, interfaces, data contracts, and governance practices that help teams build consistently, reason about quality, and evolve complex platforms over time.
I am particularly interested in the relationship between software engineering practice, architecture governance, data quality, AI-enabled workloads, cloud and mainframe modernization, security and vulnerability awareness, and the human factors that shape technical decision-making.
Research & Technical Focus
Data Platforms as System Foundations
Canonical data modeling, semantic consistency, shared contracts, governance, lineage, lifecycle management, and platform reuse.
Software Engineering Practice
Architecture review, agile programming, maintainability, vulnerability awareness, modernization, and engineering decision-making.
AI-Enabled Enterprise Systems
Applied AI and machine learning as extensions of software and data architecture, including model-supporting data foundations.
Cloud, Mainframe & Hybrid Platforms
Cloud architecture, Google Cloud data systems, IBM Z and z/OS fundamentals, integration patterns, and modernization across heterogeneous platforms.
Human-Centered Technology
Interdisciplinary interest in autism, learning differences, accessibility, school-health topics, and data-informed support systems.
Professional Experience
Leads platform-oriented data architecture for cloud-based products and data ecosystems, with emphasis on governed foundations for applications, APIs, analytics, and AI-enabled workloads.

Education
Computer Science, Software Engineering & Information Technology
Institutions: Colorado Technical University, Grand Canyon University, and University of Toronto.
Autism, Medical & Interdisciplinary Continuing Education
In addition to formal technology education, I pursue interdisciplinary study related to autism, learning differences, school-health topics, functional health education, and the relationship between technology, data, and human-centered decision-making.
- Continuing education in ADHD, autism, learning disabilities, and concussion in school contexts.
- Foundation-level continuing education in functional blood chemistry.
This section reflects continuing education and interdisciplinary study. It is not presented as clinical licensure, medical practice, or health-care authority.
