Portrait of Dean N'goma

About

My name is Dean N'goma, I'm an Automation/DevOps engineer.

I'm Dean N'goma, an Automation/DevOps engineer. I've spent the last seven years designing CI/CD pipelines, hardening production infrastructure, and running systems for teams across banking, insurance and tech — most recently specializing full-time in automation.

My sweet spot: turning whatever a team still does by hand — patching, deployments, monitoring, onboarding, even clocking in — into something that runs itself. Python and AI tooling are the newer instruments in that same toolbox.

What I do

Less firefighting. More automation.

Automation Audit

A technical audit of your workflows to find exactly where repetitive manual work is costing you time and money.

Custom Automation

Solutions tailored to your stack — Ansible, n8n, Python, Terraform — not a generic template forced onto it.

Implementation & Knowledge Transfer

I build it, ship it, and make sure your team can run and extend it without me — automation that doesn't create a new bottleneck.

Infra & SysAdmin Foundations

Everything above stands on solid ground: Linux systems, networking, monitoring and cloud run and hardened the DevOps way.

Projects

⚖️ Legal Action Platform

Freelance, since Jan 2026

Next.jsInfraSecurity

Building a dedicated platform with my lawyer to manage 25+ clients in a class action I'm part of.

  • Building it with Next.js, using Claude Code as a development accelerator
  • Fully responsible for infrastructure, deployment, storage and backups
  • Security-first: data encryption and access control from day one

🕐 Clock-in Automation

Nov — Dec 2025

SeleniumDockerVPN

Automated my own clock-in/out against an app that actively resists automation.

  • The app is built in Flutter, which normally makes Selenium useless — it renders no HTML DOM
  • Had to work headless, locate me in Spain despite the server sitting in France, and skip holidays/days off
  • Shipped as a docker-compose stack on Selenium Hub, running on a Debian 13 VM behind OpenVPN and Tailscale exit nodes

🛠️ Server Maintenance Automation

2025

n8nAutomationDiscord

Automated the monthly patch-and-restart cycle across my own fleet of virtual servers.

  • Orchestrated with a self-hosted n8n instance, driven by a color-coded spreadsheet for an at-a-glance view
  • Tracks each VM's status, last patch date, and whether its OS has gone EOL and needs upgrading
  • Sends a Discord notification the moment anything fails
