Senior IT Architect | Delivering Strategic, Integrated Solutions Across Complex Systems and Environments

Professional Overview

Versatile and experienced Senior IT Architect with a track record of delivering strategic, sustainable architecture across a broad range of industries, technologies, and project types. Adept at operating at the intersection of business and technology, I thrive in ambiguity and bring clarity to complex environments.

My strength lies in making architecture fit — whether designing greenfield systems, integrating legacy platforms, or aligning cross-functional teams around a common goal. I bring depth across enterprise and solutions architecture, combined with the ability to adapt to any methodology, stack, or scale.

With a foundation in both strategic thinking and hands-on execution, I’ve contributed to initiatives involving integration, modernization, migration, scalability, and business alignment — always with a focus on delivering real-world results, not just ideal-world frameworks.
