What I bring

I combine 15+ years of hands-on enterprise technology delivery with architectural judgment across software, data platforms, and business-critical systems. My career began in systems administration and internal business systems development, then grew into aaS platform architecture, SQL performance, cloud initiatives, and production troubleshooting.

Hands-on architecture

I design systems with an operator’s understanding of reliability, maintainability, data flow, and the realities of supporting production environments.

Business systems mindset

I understand how technology supports real operational workflows, from purchasing and fulfillment systems to enterprise platforms and reporting.

Primary focus areas

These two tracks represent the strongest themes across my resume portfolio.

SaaS & backend platforms

Backend-focused full stack and platform engineering using C#/.NET, relational data models, RESTful APIs, reusable services, reporting workflows, and scalable multi-tenant architecture.

SQL Server & data platforms

Query tuning, indexing strategy, relational database design, analytics layers, reporting workloads, and platform reliability across on-premise and cloud database environments.

Results

A few examples pulled directly from my resume set.

Near real-time data flow

Reduced processing latency from 24+ hour batch cycles to near real-time by optimizing integration patterns, event flow, and SQL-based pipelines across large-scale energy programs including TC Energy, Rover Pipeline, Baton Rouge Terminal Project, BakkenLink Pipeline System, and Atlantis Deepwater Oil & Gas Platform.

Multi-tenant SaaS architecture

Led architecture and development of a QA auditing SaaS platform serving thousands of users, including work supporting companies such as WinCo Foods, Winn-Dixie, McDonald's, Raising Cane's, Wendy's, General Mills, Diversey, Ecolab, Best Western, IHG Hotels & Resorts, and Marriott International.

Modernization without disruption

Improved reporting, analytics, and operational workflows while protecting transactional systems through clean data access layers and durable database design, including work with Project Consulting Services and Steton.
