Your IT, running quietly in the background.

I set up and manage the IT infrastructure small businesses depend on - Microsoft 365, networks, servers, and backups - using the same practices I run for enterprise environments, sized down for teams that don't need a full-time IT hire. Based in Dubai, working with clients locally and remotely, wherever you are.

Three things I handle end-to-end

01 · M365

Microsoft 365 Setup & Security

Stop spam, lock down mailboxes, and prevent costly data leaks.
Complete configuration of Microsoft 365, Entra ID (Azure AD), and Multi-Factor Authentication (MFA). Designed to protect your company’s domain, secure remote access, and ensure your emails actually hit the inbox—not the spam folder.

02 · Backup

Backup & Ransomware Protection

Ransomware-proof backups for mailboxes, SharePoint, and core files.
Fully automated, encrypted, and tested daily backups using Synology and cloud storage. If a laptop crashes, an employee deletes a critical folder, or a server goes down, your business is back up and running in minutes, not days.

03 · Infrastructure & Network

Small Office Network & Firewall Security

Fast Wi-Fi, secure remote access, and zero network downtime.
Custom setup and optimization of office routers, Ubiquiti/MikroTik firewalls, secure VPNs, segmented VLANs, and surveillance. Build a stable, high-performance network that keeps your team connected and protected from external threats.

Also handle a wider range of infrastructure work — ERPNext deployment, virtualization design (VMware / Proxmox VE), Active Directory setup, and cloud migrations. Don't see what you need? Message me to discuss — I likely handle it.

Real projects, not a sales pitch

Resolved 2026

Microsoft 365 backup gap

Problem: No offsite backup for mailboxes, Teams, and SharePoint — one deletion or ransomware event could mean permanent data loss.
Solution: Built an automated backup pipeline with Synology Active Backup, Azure app registration, and Backblaze B2 offsite storage.
Result: Every user, mailbox, and Teams/SharePoint site now backs up daily — recoverable in minutes, not never.

Resolved 2026

ERPNext deployment & zero-downtime migration

Problem: Needed a custom ERPNext environment with HR management built in, plus a path to the cloud without disrupting daily operations.
Solution: Deployed a Dockerized ERPNext image with HRMS integration on Azure, then migrated data with careful resource sizing.
Result: ERPNext and HR now run reliably on Azure with room to scale — migration completed with zero downtime and zero data loss.

Resolved 2025

Email migration to Microsoft 365

Problem: Email ran on disconnected cPanel mailboxes, missing the security and collaboration tools of a modern platform.
Solution: Migrated every mailbox to Microsoft 365 with a coordinated DNS/MX cutover and zero data loss, then onboarded the team.
Result: The company now runs fully on Microsoft 365 — proper security, shared calendars, and a clean cutover.

I'm Hossam — a senior systems & infrastructure administrator managing Microsoft 365 and on-premises infrastructure for a company in Dubai by day, and taking on a small number of independent projects on the side. Based in Dubai and working with clients here and remotely worldwide, I care about systems that keep working quietly, without drama, long after the job is finished.

Have something that needs fixing — or setting up right the first time?
