Experience

Legacy Workflow Migration to Microsoft Power Automate

I spearheaded the end-to-end migration of over 100 legacy Nintex workflows and forms to Microsoft Power Automate for the Centers for Disease Control and Prevention (CDC). This high-impact project supported a broader modernization effort, moving from SharePoint 2013 to SharePoint Online under an aggressive deadline. The migration involved workflow redesign, error handling, stakeholder coordination, and final deployment into managed environments.

Booz Allen Hamilton | SharePoint Site Consolidation and Automation

Architected and implemented a scalable SharePoint solution for Booz Allen Hamilton's federal client as a SharePoint and .NET consultant. The project focused on consolidating redundant SharePoint 2013 sites, optimizing workflow efficiency, and addressing security gaps. I delivered modern Microsoft Power Platform based automation and improved governance structures.

INPO | Business Intelligence Portal for Industry Metrics

Designed and developed a custom SharePoint-based BI portal for the Institute of Nuclear Power Operations (INPO) to centralize industry KPIs. I leveraged FAST Search, metadata tagging, and WPF-based dashboards to present real-time data insights. The solution reduced manual data processing time by over 70% and greatly improved department decision-making.

Microsoft Power Platform Dashboards and Workflow Automation

Developed and deployed custom dashboards and automation workflows across multiple agencies using Microsoft Power Platform and SharePoint 2013. These reusable components enabled real-time reporting, reduced manual reporting errors, and standardized cross-departmental communication.

Booz Allen Hamilton | Secure API Integration for SharePoint and Microsoft 365

Designed and implemented secure, REST-based integrations between SharePoint Online and third-party platforms using Microsoft Graph API. I also ensured data integrity and compliance across enterprise applications while simplifying user access to critical external systems through automated Microsoft Power Platform workflows.
