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.
