Translate operations into software
Work directly with stakeholders to understand existing processes, edge cases, approvals, security boundaries, and production constraints.
Build connected systems
Design schemas, APIs, backend logic, responsive interfaces, reporting, document automation, and integrations as one coherent product.
Own what ships
Deploy through IIS, monitor behavior, troubleshoot production issues, support users, and continuously refine applications after launch.
Experience
From infrastructure support to enterprise software leadership.
My background combines hands-on engineering with direct knowledge of the systems, users, and operational environments that software must support.
