Case studies

Real work, described plainly.

Examples from 30 years of work. Clients and employers are not named, and nothing is added that didn't happen.

A small business

One place for projects and documents, with one login

The situation

The business needed a single place to plan its work and keep its documentation, instead of scattering it.

What I did

I chose and bought the licences, set up Jira for tracking work and Confluence for documentation, connected single sign-on so staff use one login, and created and ran the first projects.

How it turned out

The team had one system for work and documents, set up and running, with one login for everyone.

An office

A network looked at end to end, from cables to training

The situation

An office wanted its network and Wi-Fi checked properly, not patched one problem at a time.

What I did

I evaluated the cable runs and equipment, recommended and purchased what was needed, installed and configured the Wi-Fi, deployed it, and trained the staff.

How it turned out

A network installed from the ground up, and a team that knew how to use it.

A global technology company

Tens of thousands of accounts, kept in order

The situation

More than 50,000 people needed their accounts created, changed and removed, in line with strict security rules.

What I did

I handled user management at that scale and integrated the platforms the company relied on, working with the teams that owned them.

How it turned out

Accounts managed across the company in compliance with its security protocols.

A technology manufacturer's customers

Teaching customers their new tools

The situation

Customers were adopting new products and features and needed to understand them, and to get help when their own networks got in the way.

What I did

I demonstrated new products, trained customers on site and remotely, troubleshot their network setups, and wrote and updated the documentation and training materials.

How it turned out

Customers were trained on their tools, with documentation to go back to.

Businesses across Puerto Rico

Building and protecting networks island-wide

The situation

Businesses in the south and north of Puerto Rico needed computers and networks installed and kept running.

What I did

I installed hardware, operating systems and software, administered Windows servers and clients, built and maintained the networks, and recommended and implemented security: firewall policies, router access lists and network monitoring.

How it turned out

Networks installed and maintained across both parts of the island, with security built in.

Ang3l Tech (my own business)

Running my own business systems like a careful IT department

The situation

A one-person business still needs a website, a way to receive requests, and systems that don't break when something changes.

What I did

My website and customer requests run on Odoo in my own homelab. Every change goes to a test copy first, with a backup before each update. The contact form has spam protection and sends me an alert for every real message.

How it turned out

The same care I would give a client, applied to my own systems first. This website is the result.
