About Me
Project Director – Banking IT Transformation & Migration Expert
With over 25 years of experience as a Project Director, I specialize in delivering large-scale IT transformation and migration programs within the banking sector. My expertise lies in steering complex, multi-phase projects from inception to completion, focusing on system integration, legacy migration, and digital transformation initiatives.
I have successfully led cross-functional teams across global locations, ensuring the seamless execution of mission-critical projects that align with business objectives and regulatory compliance. My extensive knowledge of banking systems, combined with a strategic approach to IT modernization, enables me to manage risk, optimize resources, and deliver projects on time and within budget.
A key strength of mine is stakeholder management—working with C-level executives, external vendors, and internal teams to ensure clear communication, alignment, and successful outcomes. I am adept at driving change in highly regulated environments, always maintaining a focus on minimizing downtime and ensuring data integrity during migrations.
In an industry where technological evolution is constant, I bring a wealth of experience and a forward-thinking approach to every project, ensuring that IT solutions not only meet current needs but are also scalable for future growth.
