Principal Systems Architect & Software Engineer
I architect and build production software systems end to end — database through frontend, infrastructure through application layer. Over 25 years I've designed platforms that run reliably for a decade or more, delivering multi-million dollar cost savings and making the strategic build-vs-buy decisions that shape how engineering teams operate. My current focus is enterprise observability and infrastructure analytics: full-stack platforms with distributed agent architectures providing operational intelligence across hundreds of thousands of field devices spanning more than 20 jurisdictions.

2023–Present
Sole architect and engineer of a distributed operational intelligence platform serving operations, field service, and executive reporting across hundreds of thousands of field devices spanning 20+ jurisdictions. Correlates millions of records across external vendor APIs and previously siloed internal departmental systems — producing a unified view unavailable from any single source. Platform analysis identified discrepancies resulting in multi-million dollar cost savings; that analytical capability is now automated and operational going forward.
2013–Present
Built from the ground up for a wholesale distribution business — full ownership from requirements through a decade-plus of production operation. Designed for longevity from the start; the system has supported significant company growth throughout.
