Root cause, not symptom
I chase failures to their origin instead of papering over the surface. A fix that treats the cause holds; one that treats the symptom comes back.

Hi, I'm Patricio
I find root causes, not symptoms. Automation that lasts, bug reports that need zero follow-up questions.
profile.spec.ts - testing since 2017
- API + E2E automation that lasts
- root causes, not symptoms
- bug reports with zero follow-ups

How I work
Quality is a way of working, not a phase at the end.
Six habits that show up in everything I ship.
Bug reports engineers act on now
Clear repro, device/OS/build, evidence, and a root-cause hypothesis, so the person fixing it starts fixing, not investigating.
Options + a clear recommendation
Trade-offs and risks laid out, then the smallest, lowest-blast-radius fix recommended first. Decisions, not just findings.
Trustworthy signal
Real failures separated from noise. CI digests and targeted retries for genuinely flaky steps keep the green/red meaningful.
Closes the loop
Tests ready before the meeting, scope matched to team bandwidth, and every item tracked to done. Nothing left dangling.
Prevention over patches
Standardized conventions, remediation tickets, contract validation, and security gates so the same class of bug does not recur.
Day to day
What I actually do
The work behind the outcomes, abstracted from real engagements.
Test automation (API + E2E)
Failure triage & root-cause analysis
Release readiness / RC validation
Cross-platform mobile + web parity
API contract & schema validation
CI health & visibility
Quality signal & trend reporting
Security & dependency (CVE) scanning
Cross-team QA ↔ dev ↔ client coordination
