About Bryan
QA Automation Engineer & Android Developer | Remote Europe
With 2.5+ years of enterprise experience as the sole QA Engineer for an 8-developer team at NTT DATA, I specialize in building robust, reusable test automation suites that ensure high-quality software delivery.
Key expertise:
• Test Automation: Java, Selenium, Cucumber, Pytest, Cypress, Playwright, Postman, REST/JSON/JWT, Allure Reports (with video & flakiness metrics)
• Mobile Development: Native Android (Kotlin, Jetpack Compose, MVVM, Hilt, Material 3)
• Full-Stack & Cloud: React, TypeScript, Django REST, Firebase (Firestore, Auth), PostgreSQL, Render, Supabase, AWS S3, Docker
Highlights from my career:
• Built from scratch a suite of 50+ reusable E2E tests for the SEAT:CODE CUPRA project.
• Achieved 95% test coverage in personal full-stack projects (see GitHub).
• 11 production-ready personal projects live on GitHub, including Android beta apps, Pytest+Selenium suites, and a personal portfolio website.
I help startups, SMEs, and enterprises launch reliable web, mobile, and e-commerce applications by combining enterprise-level QA practices with modern development. Whether you need automated testing for an existing product, a native Android app from scratch, or end-to-end quality assurance, I deliver clean, maintainable solutions with strong focus on performance, security fundamentals (OWASP), and user experience.
Currently based in Spain (EU citizen), fully remote preferred, but open to hybrid/onsite depending on the project. Planning relocation to Zurich – open to Swiss opportunities.
Available for short- and long-term missions in QA Automation, Mobile Development, and Testing.
