About

Professional summary

I am a results-oriented Senior Technical Project and Program Manager and Scrum Master with more than 15 years of experience leading agile product delivery, enterprise software development, infrastructure automation, and complex programs in highly regulated industries.

I specialize in improving delivery predictability through value-flow management, including work in progress, lead time, throughput, dependencies, backlog quality, and milestone governance. I guide cross-functional engineering, SRE, business, and vendor teams toward transparent, specification-driven execution.

I have led portfolios of concurrent initiatives across financial services, healthcare IT, cloud and data center migrations, AI, RPA, and enterprise platform delivery. My experience includes end-to-end program governance, risk management, budget control, change management, stakeholder alignment, and production incident coordination.

I am experienced in Agile, Scrum, SAFe, Kanban, Waterfall, and hybrid delivery models. I facilitate PI Planning and agile ceremonies while adapting governance structures to improve collaboration, planning quality, and client alignment.

I use enterprise work-management and analytics tools such as Jira, Azure DevOps, Confluence, Power BI, Smartsheet, MS Project, and ServiceNow. I also leverage AI assistants and AI-first workflows to support analysis, planning automation, and delivery optimization.

I bring a collaborative leadership style based on influence, transparency, continuous improvement, and practical execution. My goal is to help organizations deliver high-value technical outcomes predictably while maintaining strong financial, operational, and risk controls.
