About Mateo Javier

Does your team release features without enough time for thorough testing? I help you detect errors before they reach production with manual functional tests that protect your end-users' experience.

I am aHigher Technician in Systems Analysis**, specializing in **Manual QAand **Functional Analyst**, with certified training in test automation that I increasingly apply in my daily work. I currently work at AtomIT, where I test and actively participate in the development of Nexus, their SaaS management platform. I also work as a functional analyst and manual tester on custom-developed systems for various clients (e.g., municipal systems). This includes field functional analysis—visiting the sectors where systems are implemented to see how they are used in practice and solve real problems—and both on-site and remote technical support. This combination gives me a comprehensive view of the product, not just the bugs.

What I usually deliver:
  • Design and execution of functional test plans (smoke, regression, exploratory)
  • Clear documentation of bugs and test cases (Trello, Jira), including Bug Report Generator, a tool I developed to streamline and standardize my reports
  • API testing with Postman
  • Functional analysis and definition of acceptance criteria with the product team
  • Use of AI tools (ChatGPT, Claude, Gemini) to speed up log analysis, test case generation, and repetitive tasks

I have training inAutomated QA Testing(Digital House — Java, Selenium, JUnit, Cucumber, Postman) and knowledge of web development (React, Next.js, Node.js) and databases (SQL, PostgreSQL) that allow me to understand the technical architecture behind what I test, not just follow a test script.

I adapt easily to agile methodologies and to teams with both technical and non-technical profiles.
