Businesses often rely on spreadsheets, inboxes, manual approvals, and disconnected SharePoint lists long after those processes have outgrown them. I design Microsoft 365 and Power Platform solutions that replace those workflows with scalable, maintainable business systems.
I have 8 years of Microsoft 365 experience and deliver projects from initial discovery through architecture, development, testing, deployment, documentation, training, and production support.
My core services include:
• Power Apps Canvas applications
• Power Automate workflows, approvals, document generation, and notifications
• SharePoint Online intranets, information architecture, permissions, and migrations
• Microsoft Graph and REST API integrations
• PowerShell automation
• Ticketing, scheduling, intake, inventory, CRM-style, and request-management systems
• Technical documentation and administrator handoff
I have built solutions for finance, legal, operations, sales, HR, and field-service teams, including enterprise systems with complex business rules, role-based access, automated data intake, multi-stage approvals, and external integrations.
My focus is not simply making an app work. I design around scalability, performance, security, maintainability, and the people who will ultimately use and support the solution.
Clients receive a complete delivery process: clear communication, thoughtful architecture, reliable development, practical documentation, and a system designed for long-term business use.
