Building the
future of M365
your way.
T4HYN delivers cutting-edge Microsoft 365 development — from SharePoint frameworks and Teams extensions to Power Platform solutions and Copilot integrations.
Every layer of the
M365 ecosystem
From custom SPFx components to enterprise-grade automation, we build and extend the full Microsoft 365 stack.
Custom SPFx web parts, extensions, and modern SharePoint experiences built to scale with your organization.
Tabs, bots, message extensions, and meeting apps that integrate deeply into your Teams workflows.
Low-code and pro-code solutions using Power Apps, Power Automate, and Power BI that actually perform.
Extending Microsoft Copilot with custom plugins, connectors, and AI-driven solutions built on Azure OpenAI.
Serverless APIs, Azure Functions, and Logic Apps that power the back end of your M365 solutions.
Lift-and-shift or full redesign — we migrate legacy SharePoint and custom apps to modern M365 architecture.
M365-native.
Zero fluff.
We live inside the Microsoft ecosystem every day. Our team doesn't generalize — we specialize, and that depth shows in every deliverable.
We don't dabble. Everything we do is Microsoft 365 — that specialization means faster delivery and fewer mistakes.
Led by developers, not consultants. We write clean, maintainable code and hand it over with full documentation.
Every solution follows Microsoft's security baseline — least privilege, Entra ID, conditional access, and compliance-ready outputs.
Agile sprints, real demos, and frequent releases — you see progress weekly, not at the end of a long waterfall.
From brief to build,
with no surprises.
A tight four-stage process designed for M365 projects — shaped around your governance, timelines, and tenant constraints.
We audit your tenant, understand your users, and map the gap between where you are and where you need to be.
We design the technical blueprint — components, APIs, data flows, and security model — before a line of code is written.
Agile sprints with weekly builds. You test in a dev tenant throughout, not just at the end.
Staged deployment with rollback plans, knowledge transfer, and ongoing support options tailored to your team's capacity.
Tools and platforms we work with every day
