Fractional M365 & Business App Engineering in Fairhope & South Alabama
I partner with 10–50 person companies across Baldwin County and the greater Mobile Bay area to replace fragile spreadsheets, automate operational bottlenecks, and build secure tools using Microsoft Teams, SharePoint, and Power Apps—without the full-time hire.
The Regional IT Gap
When your organization outgrows standard MSP support.
Most 10–50 person businesses in South Alabama already have an IT provider handling helpdesk tickets, firewalls, and PC deployments. That works for basic tech support—until you need custom workflow automations, internal web portals, or secure external collaboration.
The Excel Ceiling
Operations running on shared workbooks that corrupt, lock concurrent editors out, and lack row-level permission controls.
Orphaned Flows
Critical automations tied to former employees that break unannounced when accounts or passwords change.
The External Wall
Subcontractors and clients needing to submit RFPs or review files without risking accidental exposure of internal SharePoint sites.
The MSP Gap
Your IT provider handles hardware and email, but explicitly excludes custom business logic, internal apps, and database integrations.

Local presence with enterprise experience.
While my engineering practice serves organizations across the country, I am based in Fairhope, Alabama. For local leadership teams, that means you have access to direct, in-person discovery and architectural strategy sessions when you need them.
I regularly meet with clients across the Eastern Shore and Mobile:
