Backend developer in Artur Nogueira, São Paulo, Brazil.
I am responsible for the API of Pacifco®, the industrial predictive-analysis system built at Engefaz Engenharia: data ingestion, queue-based workers, digital signal processing, and legacy architecture rework. Python, SQL Server and REST APIs, 10+ years.
Two domains, on purpose:
Signal processing and predictive maintenance. Vibration data from industrial equipment: time-to-frequency domain transforms, digital filtering, envelope demodulation, acceleration-to-velocity integration. A trained classifier running in production produces automated equipment diagnoses.
Exercise science. CREF-licensed physical education professional. Evidence-based prescription: clinical question, literature appraisal, and a prescription justified against the evidence rather than convention.
How I work: I specify the outcome that needs to exist and the criteria that verify it, rather than dictating the procedure. My practice moved from prompt engineering to context engineering and, currently, intent engineering.
One rule I hold to: I state what I verified and what I inferred as separate claims, and I name the source of each.
Most of my work lives in private repositories.
