Google Workspace to Microsoft 365 Migration

Environment

Existing Google Workspace setup that needed to move into Microsoft 365 without losing access to mail and files.

Role

Prepared the new Microsoft 365 environment and kept the move structured.

Execution

Migrated mail and Google Drive data to OneDrive, configured DNS, and deployed Sophos and Atera through Azure.

Outcome

The client transitioned to Microsoft 365 with the core services ready for day-to-day use.

Migration flow

Migration work transfers mail, data, and DNS.

Security Deployment with Sophos MDR

Built a repeatable rollout path for Sophos MDR agents using Atera RMM and tracked the deployment through completion.

Result

The rollout became easier to manage and easier to verify across endpoints.

Case study

Security Deployment with Sophos MDR

Environment

A client onboarding path that required endpoint protection to be rolled out in a controlled way.

Role

Made the deployment reliable instead of handling each machine manually.

Execution

Used a script through Atera to deploy the agent, then monitored the rollout and checked that the endpoints were caught successfully.

Outcome

Deployment was standardized and could be tracked instead of guessed.

Sophos rollout flow

A scripted rollout pushes the agent and tracks it.

Full Client IT Onboarding

Set up Microsoft 365, backups, and endpoint security for a new client environment, with support during the handover period.

AI & Automation

Workflow support

AI agents, Telegram, Docker, APIs, and MCP tools connected into practical workflows.

Oz Amira uses AI agents to help with development, research, and repetitive work.

The useful part is orchestration: Telegram gateway, Docker, APIs, and MCP tools are connected into a workflow that makes troubleshooting and small automation tasks easier to run and repeat.

Use AI agents to speed up development, research, and repetitive work without making AI the headline.
Connect Telegram gateway, Docker, APIs, and MCP tools so tasks can move through one practical workflow.
Focus on orchestration, troubleshooting, and workflow design that a non-technical reader can understand quickly.
