I'm a Full-Stack Developer & QA Automation Engineer πŸš€

My name is Ulises, I'm 28 years old and I live in CABA, Buenos Aires. πŸ‡¦πŸ‡·

  • 🌱 My mission is to use technology + testing knowledge to build reliable, scalable, and high-quality applications that make an impact.

  • πŸΆπŸ“± I gained valuable experience in mobile app development with React Native, working under Scrum methodology on a pet adoption NGO project.

  • πŸ’»πŸ§‘πŸ»β€πŸ’» At Penta Security Solutions I started as a QA Analyst, where I specialized in:

    • Functional, regression & integration testing
    • Performance testing with JMeter
    • Automation with Jest + Supertest (backend APIs)
    • Playwright & Cypress for E2E testing
    • Defining test strategies, metrics, and coverage in financial environments

    Later, I transitioned into Frontend Development, where I applied my QA mindset to deliver robust and user-focused platforms.

  • πŸ“ˆ I’m continuously learning and expanding my skills in:

    • TypeScript & Node.js (monorepos, project references, design patterns)
    • Cypress & Playwright (UI + E2E automation)
    • BDD with Cucumber/Gherkin
    • Test design patterns: Screenplay Pattern vs Page Object Model
    • CI/CD pipelines (GitHub Actions, Jenkins, GitLab CI)
    • Performance monitoring & QA dashboards with Power BI
    • Databases: MongoDB & PostgreSQL
  • πŸŽ“ Graduate of Henry Bootcamp (Web Applications: JS, React, Node.js). Later, Teaching Assistant, helping students onboard, solve technical issues, and practice teamwork.

  • πŸ“· Extra skills: photographer, audiovisual producer, community manager and experience creating radio/streaming shows.

  • ⚑ Fun fact: I have discromatopsia β€” so yes, I literally debug the world in a different light 🌈.
