About Me

I'm a ServiceNow Sr. Consultant and Infrastructure Engineer with 10+ years spanning platform development, team leadership, operational management, and hands-on systems engineering. I work across the full IT spectrum - not just one slice of it.

At Fujitsu I managed and optimised costs across multi-account helpdesk operations, owned P&L as acting Operations Manager, and built workforce forecasting tools from scratch. Beyond corporate IT, I've consulted for local businesses on their digital journey - brand identity, logo design, web presence, and lead generation - helping them go from idea to market-ready.

Today I consult and deliver ServiceNow solutions at Cognizant and maintain a production-grade Proxmox homelab running 20+ Docker containers, a self-hosted Mailu mail server, n8n automation workflows, and a custom-built Claude MCP integration. I don't just understand IT - I build with it, manage it, and sell it.

Things I build and tinker with outside of work

n8n Automation Hub

Self-hosted n8n instance with PostgreSQL and Redis backends, orchestrating automated workflows across Odoo, Nextcloud, Jotty, webhooks, and external APIs. Acts as the integration backbone connecting every service in the stack.

Auto Shop Customer Retention

Built a daily automation for a local mechanic shop struggling with customer churn. Every day the system checks the database for vehicles with inspections due the following month, filters out customers who have already visited, and sends personalised email and SMS reminders to everyone else.

Cloudflare Zero-Trust Access Layer

All 20+ services are exposed exclusively through Cloudflare Tunnels - zero open inbound ports on the host. Every subdomain (*.diogoandrade.com) routes through an encrypted tunnel with access policies, DDoS protection, and Cloudflare's edge network.
