I build Copilot Studio agents and AI automations on the Microsoft stack that actually get used.
My focus is Copilot Studio agents, AI agents, and Power Automate workflows. Production systems grounded in SharePoint, Dataverse, Microsoft 365, and Teams that teams rely on daily. Not demos. Not proofs of concept. Real systems in production.
Alongside that I work in .NET, ASP.NET MVC, and React, building and maintaining full-stack web applications for clients across Australia and the US.
What I work on:
→ Copilot Studio agents for document handling, guided workflows, and internal automation
→ AI agents grounded in your own SharePoint, Dataverse, and Microsoft 365 data
→ Copilot Studio agents for finance and compliance workflows, with human review built in
→ Power Apps canvas and model-driven apps with SharePoint, SQL, and Dataverse backends
→ Power Automate flows for approvals, document generation, and compliance outputs
→ Azure AI Foundry, AI Builder, and LLM prompt engineering inside Power Platform
→ .NET, ASP.NET MVC, and React web applications
→ Azure SQL, Microsoft Graph, and SharePoint REST API integrations
I take on ongoing work and I move fast. No agency overhead, no layers between you and the person building. Most of my best client relationships started small and grew into something consistent.
If you have something to build, message me. I will tell you straight whether I can help and what it will take.
