I define network solutions, automate repetitive tasks and document each improvement.
Documented cases in automation, backups and the diagnosis of a GPON incident.
I built an n8n workflow that reads three files, checks the information and generates a Word document for review.
With the workflow, I reduced the manual preparation of each report from 1–2 hours to about 10 minutes of review.
View case
I built an n8n workflow that schedules commands per device, runs backups over SSH and logs each result.
I automated a backup cycle every 15 days for 300 devices across 60 sites.
View caseI investigated intermittent outages and problems opening web pages at an educational centre. The diagnosis ruled out radio-frequency issues and narrowed the incident to connectivity between the ONT and OLT.
The fault was identified as a provisioning problem. After the system was reprovisioned, the service worked again and the procedure was recorded in a provisioning guide.
View caseThree steps for solving network problems and leaving solutions that are easy to repeat.
Review the available information and rule out hypotheses until the source of the problem is located.
Test equipment, configurations and outputs before adopting an improvement.
Write down the procedure and prepare material that makes the solution repeatable.
