Capabilities & Architecture

Get full value out of the Microsoft 365 licenses you already pay for.

Most organizations use less than 20% of what SharePoint Online and Power Platform can do. We build the custom web parts, automated workflows, and data connections that turn M365 into a tailored operations platform.

SPFx • React • TypeScript

Custom SharePoint (SPFx) Web Parts & Extensions

The Bottleneck: Out-of-the-box SharePoint web parts hit a wall the moment your team needs custom filtering, dynamic dashboards, role-specific views, or external API connections.

We engineer production SharePoint Framework (SPFx) web parts, application customizers, and list command sets in React and TypeScript—deployed cleanly to your tenant App Catalog with zero external hosting overhead.

What We Deliver:
  • Custom SPFx React web parts & interactive intranet widgets
  • Application customizers (global navigation headers, alerts & footers)
  • PnPjs, REST & Microsoft Graph API data integrations
  • SPFx Field Customizers & ListView Command Sets
Power Automate • Logic Apps

Power Automate Workflows & Approval Engines

The Bottleneck: Critical approvals, onboarding steps, and document routing stall in email chains where nobody knows who has the ball or which version is final.

We architect resilient Power Automate cloud and desktop flows with multi-stage approvals, automated PDF/Word document generation, conditional routing, and audit logging across SharePoint, Teams, and Outlook.

What We Deliver:
  • Multi-stage parallel & sequential approval workflows
  • Automated contract, invoice & report generation to PDF
  • Real-time Microsoft Teams adaptive cards & Outlook action alerts
  • Scheduled data syncs between SharePoint Lists, SQL, and external APIs
SharePoint Online • Architecture

SharePoint Hubs, Sites, Lists & Permissions Governance

The Bottleneck: Years of organic growth leave organizations with sprawling document libraries, broken inheritance permissions, and slow lists crossing the 5,000-item threshold.

We design and restructure SharePoint Online hub sites, department portals, metadata taxonomies, indexed high-volume lists, and role-based security groups that stay fast and maintainable.

What We Deliver:
  • Executive intranet hubs & department communication sites
  • High-volume SharePoint List schema design & indexing
  • JSON list/column formatting & custom Power Apps forms
  • Clean M365 security group & permission governance
Graph API • Excel/VBA • MS Project

M365 Tenant Migrations & Office / VBA Automation

The Bottleneck: Analysts and project managers lose hours every week copying CSV exports into Excel, reconciling Microsoft Project schedules, or migrating mailboxes and OneDrive data.

We build automated pipelines connecting Excel, Outlook, MS Project, and the Microsoft Graph API—eliminating manual spreadsheet assembly and handling cross-tenant M365 migrations cleanly.

What We Deliver:
  • Cross-tenant Exchange & OneDrive migrations via Microsoft Graph API
  • Automated Excel & Outlook VBA financial reporting pipelines
  • Master Microsoft Project schedule synchronization & rollups
  • Legacy macro modernization into SharePoint & Power Platform
