About Me

Software engineering leader with 13+ years of hands-on experience designing, modernizing, and delivering enterprise software across manufacturing, financial services, and government environments. I combine deep technical expertise in C#, .NET, Python, React, microservices, APIs, Azure, AWS, Kubernetes, cloud operations, data platforms, observability, and applied AI/ML with proven capabilities in technical direction, architecture governance, cross-functional leadership, and delivery execution.

Currently serving as an IT-Engineer Software Lead at Sherwin-Williams, where I own technical direction, architecture standards, delivery roadmaps, and team development. I have delivered $6M+ in annual revenue impact through enterprise integration, built production AI capabilities including GPT-4 chatbots and Python-based ML recommendation models, and led initiatives involving cloud modernization, multi-region HA/DR, and observability infrastructure. I thrive on ambiguous, high-impact problems where strong architecture, practical execution, and measurable business outcomes are equally important.
