AI & Automation Consultant.
I’m Sergio Afonso. I analyse business processes, design the system around them and implement reliable automation across workflows, APIs, data and infrastructure.
My current commercial focus is recruitment operations, but the underlying work is broader: reducing operational friction with systems that remain understandable after launch.
Simple principles for dependable systems.
Automation before AI
Use deterministic automation when it solves the problem. Add AI only where interpretation or generation creates clear value.
Humans stay in control
Important business and people decisions should remain reviewable, reversible and owned by a person.
Reliability over demos
Validation, logs, alerts and controlled failure paths matter more than an impressive happy-path prototype.
Maintainability by design
A useful system should be documented, observable and understandable by someone other than its original builder.
A compact, practical toolset.
The stack follows the process. Tools are implementation choices, not the service itself.
