Custom business apps and reliable M365 automation—without the full-time hire.
I help growing organizations and business units eliminate operational friction by transforming disconnected spreadsheets into secure, automated internal tools on Microsoft Teams, SharePoint, and Power Apps.
Microsoft 365 & Power Platform consulting based in Fairhope, Alabama — serving Mobile, Baldwin County, and organizations nationwide.
Common Bottlenecks
You’ve outgrown basic spreadsheets, but aren't ready for enterprise bloat.
Most growing organizations and business units run critical operations on Microsoft 365, but end up stuck in manual workarounds or fragile automations that nobody knows how to maintain.
The Excel Ceiling
Workflows locked inside shared workbooks that corrupt, lock concurrent editors out, and lack row-level permission controls.
Orphaned Flows
Critical automations tied to ex-employee accounts that fail unannounced during password updates or MFA resets.
The External Wall
Subcontractors and clients needing to submit RFPs or review data without risking accidental exposure of internal SharePoint sites.
The MSP Gap
Your IT provider handles laptops and mailboxes, but explicitly excludes custom business logic, internal apps, and database integrations.

Tenant Readiness & Governance Audit
Before activating generative AI or custom agents, we secure your tenant to guarantee agents never surface confidential salaries, executive communications, or customer records to the wrong users.
- SharePoint Permission & Link Auditing:Surface and remediate broken permission inheritance, "Everyone except external users" shares, and legacy links to prevent catastrophic data leaks via AI search.
- Microsoft Purview & DLP Controls:Configure sensitivity labels, Data Loss Prevention (DLP) policies, and Entra ID conditional access controls to govern agent data retrieval.
- Authoritative Knowledge Mapping:Identify curated, verified document libraries and prune outdated sprawl so agents only reference authoritative operational truth.
Custom Agent Engineering
With governed data in place, we build intelligent, multi-step AI agents directly inside your Microsoft 365 tenant that automate complex workflows and reduce operational toil.
- Bespoke Copilot Studio Agents:Build purpose-driven agents grounded in your line-of-business data, internal knowledge bases, and custom REST APIs.
- Autonomous Flow & Connector Actions:Trigger robust Power Automate flows, Azure Logic Apps, and custom connectors so agents can execute real operational actions—not just talk.
- Native Teams & SharePoint Deployment:Deploy agents where your team already works: pinned inside Microsoft Teams channels, direct 1:1 chat, and embedded SharePoint portals.
Battle-tested patterns and production case studies solving real operational friction.
