About

Professional summary

I am a Senior QA Engineer and test automation professional with experience in software quality engineering, test strategy, continuous integration, and RPA development. I build scalable, deterministic quality practices that improve product reliability and delivery confidence.

At Fluxo, I was responsible for quality assurance across six products, including a foreign-exchange platform, back-office applications, services, a partner portal, and an AI copilot. I established the QA program from the ground up, implementing risk-based testing, acceptance-criteria traceability, regression policies, and measurable quality indicators.

I specialize in end-to-end, API, unit, and contract test automation using Playwright, TypeScript, JavaScript, Python, Vitest, Testing Library, MSW, xUnit, NSubstitute, and Postman. I have scaled CI automation suites while reducing manual execution and eliminating flakiness in critical E2E test suites.

My experience includes CI/CD quality gates, Azure DevOps Pipelines, Git, Docker, SonarCloud, SQL validation, performance testing, and observability with Datadog. I also work with AI-assisted failure classification and defect-triage automation.

My automation career started in 2018 through RPA development. I have delivered and supported process automations for healthcare, financial, logistics, and service-sector operations using Automation Anywhere, UiPath, Power Automate, Python, and related platforms.

I am available for remote roles across Brazil and hybrid opportunities in the Campinas and Valinhos region. I bring a process-oriented mindset, strong business analysis capabilities, and a focus on stable production-ready automation solutions.

Career history

QA Analyst — Test Automation Fluxo

I structured the QA program from scratch for six products, including a foreign-exchange platform, back-office applications built with Next.js, a .NET 8 backend, a Python service, a partner portal, and an AI copilot. I implemented risk-based test strategy, acceptance-criteria traceability, and regression policies.

I scaled CI automation to approximately 3,400 tests using Playwright E2E with TypeScript, Vitest, Testing Library, MSW, xUnit, and NSubstitute, reducing manual execution to 3.5%. I eliminated flakiness in the critical E2E suite through resilient global setup and deterministic network-response waits.

I introduced escape rate tracking, reduced production-defect rates per sprint from 83% to 20%, and corrected CI quality gates to block failed tests. I automated REST API and contract validation, validated SQL persistence, integrated Datadog Error Tracking with Azure DevOps, and built AI-supported failure classification and triage automations.

Systems Analyst — RPA Developer Unimed Porto Alegre

I developed and maintained RPA robots for regulatory and supplementary healthcare operations. My work covered process assessment, technical design, testing, approval, and production support.

I implemented monitoring routines and exception handling for business and system failures. These automations supported processing continuity and compliance for medical transactions.

Systems Consultant — RPA Developer BRQ Digital Solutions

I developed and supported enterprise automations using Automation Anywhere, UiPath, and Python for financial, logistics, and service-sector clients. I performed process assessments and supported testing and approval activities.

I delivered an automation that reduced insurance consolidation processing time from seven days to one day. I focused on stable robot operation, operational success, and sustainable production support.

RPA Developer Bosch Service Solutions

I developed and monitored RPA robots and automation workflows in an international shared-services center. I used Automation Anywhere, Power Automate, Catalytic, OutSystems, and Power BI.

I automated data reconciliation, management reporting, and service workflows. These solutions reduced manual effort and shortened request cycle times.

Administrative Assistant Bosch Service Solutions

I managed assets and access controls while beginning my automation career in 2018. I developed my first automation robots using Automation Anywhere, OutSystems, and Catalytic.

The role strengthened my understanding of administrative processes, operational controls, and process mapping. It established the foundation for my later RPA development and quality automation work.

Fiscal and Administrative Assistant Bosch

I supported fiscal and administrative activities, including shipping audits and report generation with SAP and RedPrairie. I also contributed to process mapping initiatives.

This experience developed my operational understanding, reporting discipline, and ability to identify process-improvement opportunities.
