Operations and technology manager, applied AI. Based in Viçosa, Brazil, working remotely.

Bachelor's degree in Information Systems and a registered advertising professional in Brazil. I have been building websites since 2011 and working at an advertising agency since 2010, where I started as a web systems analyst and today I am responsible for the operation, the commercial side and every technology delivery.

My work connects both ends: the business problem and the system that solves it. I handle servers, databases and integrations, not only the layout, and what I deliver stays online under my operation.

Zammir, large format printingAccount service and graphic design

  • Account service and artwork for large format printing, from banners and storefront signage to point of sale material.
  • Where I learned deadlines and finishing: a file that goes to the press gets no second chance, and that is the same standard I apply to anything that goes live.
Projects

The problem, the tools and what stayed standing.

Education

School analytics dashboard

The school data was locked inside the academic system and the coordination team made decisions from spreadsheets exported by hand.

Tools
Python Dash and Plotly PostgreSQL Academic system API systemd timer gunicorn Docker and Traefik
Live in two campuses, in two cities, with role based access. Found along the way: the extraction silently dropped records whenever the API failed, and the real absence count of one campus was twice what the dashboard showed.
Education

Enrollment copilot

The admissions office handled families over WhatsApp and nobody knew how many had been left without an answer.

Tools
Evolution API n8n PostgreSQL Claude and OpenAI Triage in SQL
The AI drafts the follow up and the school approves it before anything is sent, never the other way around. Outcome: interested families that existed nowhere in the CRM surfaced on the first pass over the history.
Public transport

AI agent on WhatsApp

Passengers asked about schedules and routes at any hour, including when there was nobody available to answer.

Tools
Evolution API n8n PostgreSQL Language model Linux VPS
It answers around the clock and every conversation is stored in the database, which makes what the agent replied auditable.
Public sector

AI assistant for a water and sanitation consortium

The consortium received the same technical questions every day, by phone and email.

Tools
On site chat PHP and JavaScript PostgreSQL Conversation dashboard Security review
Beyond the assistant, I reviewed the application: SQL injection, an exposed API and a credential hardcoded in the source were found and fixed.
Media

Automated news portal

A project of my own: publish regional content every day with no newsroom, on a site fast enough for mobile.

Tools
WordPress custom theme PHP n8n AI rewriting RSS Lighthouse Structured data
Theme written from scratch instead of a purchased one. Measured gain: the home page main content went from 9.5 seconds to 1.7 seconds to render.
Security

Hosting incident response

A hosting account was compromised and every site in it showed up infected on the same day.

Tools
SSH WP-CLI Code signature search Credential rotation WordPress hardening
I cleaned the sites and killed the persistence before the payload. Root cause: a leaked credential, not a plugin flaw, which changed the whole remediation.
Tools and experience

What I work with, and where I have used it.
