Ramses José Guzmán Peyre
Software Engineer
CABA,Buenos Aires
Summary
I am a software professional with a unique career trajectory, transitioning from a Full-Stack & Integration Developer into a Senior Software Quality Engineer specializing in test automation infrastructure. Because I spent years building web applications and enterprise web services, I bring a developer's mindset to QA, enabling me to design robust, highly efficient automation frameworks from the ground up. My expertise spans the entire software lifecycle, from integration development via the MuleSoft Anypoint Platform to building end-to-end testing pipelines that integrate seamlessly into CI/CD workflows.
Core Technical Expertise:
- QA & Test Automation: Selenium, Playwright, WebdriverIO, JUnit, TestNG, RCPTT/ECL, JMeter
- Languages & Environments: Java (J2EE), JavaScript/TypeScript, Node.js, Python, PHP, Groovy.
- Integration & API Testing: MuleSoft Anypoint Studio (3/4), DataWeave, MUnit, Web Services (REST/SOAP), Postman, SoapUI, WSO2
- Infrastructure & CI/CD: Jenkins, Continuous Integration pipelines, SQL, Data Warehousing
I thrive on bridging the gap between development and quality assurance, ensuring software is not only functional but resilient and scalable.

Work History
Software Engineering SMTS
Salesforce
Provincia de Buenos Aires, Argentina
08.2022 - 06.2026
- E2E QA Automation Engineer at Mulesoft / Salesforce
- Senior Software Engineer (SMTS) on MuleSoft Platform Quality Engineering at Salesforce, specializing in end-to-end test automation and platform quality for core products including Mule Runtime 4.x, Anypoint Studio 7.x, and Anypoint Code Builder (VSCode).
Designed and built the CAP-based E2E automation framework for Anypoint Code Builder, the first solution purpose-built for multi-driver VSCode extension testing — adopted as the team standard and integrated with SauceLabs and CI/CD pipelines (Kilonova).
Owned the Mule Runtime 4.x & Anypoint Studio 7.x release sign-off process as Q3 POC, validating every Release Candidate across CloudHub 1.0 & 2.0, RTF, Standalone, GovCloud (FIPS/Java 17), and MMP channels before GA — while also delivering key platform tools including MAMT, SIS MCP Server v2, and the Environment Stability automation suite. - 3 years 11 months

Contributed to the early adoption and growth of the CAP automation framework within the Q3 team, building Mule test applications and validating new Runtime features across multiple deployment flavors, while proactively identifying and escalating pre-GA bugs in cross-team channels to prevent production impact.
Developed strong expertise in the Anypoint Platform ecosystem — covering Runtime Manager UI/API, Mule Maven Plugin (MMP), Anypoint Studio, and multi-environment deployment pipelines — laying the technical foundation for a promotion to SMTS in August 2022. - 1 year 9 months
