QA Engineer with a focus on test automation, CI reliability, and building stable, reproducible systems.
I combine structured test design with hands-on development to deliver well-tested, production-ready applications.

ISTQB CTFL certified • Background in structured analysis • Strong focus on modern QA and automation practices

🎯 Open to: QA / Test Engineer • Test Automation Engineer • QA-oriented Developer roles
📍 Based in Germany • Open to relocation within Europe
🗣 Languages: English (native), German (professional), Spanish (professional)

Full-stack MERN application with a strong emphasis on testability, system reliability, and CI-backed regression control.

Engineering:

• Layered frontend/backend architecture with clear separation of concerns
• REST API design with authentication and protected routes
• Consistent data handling and CRUD operations
• Deterministic environment configuration for reproducibility

Testing & QA:

• Automated regression across backend, frontend, and E2E layers
• Test isolation and controlled environments (MSW, database lifecycle control)
• API validation and failure-mode testing
• CI integration as a quality gate to prevent regressions

Tech: MongoDB, Express, React, Node.js, JavaScript, TypeScript
Testing: Jest, Supertest, React Testing Library, MSW, Playwright
CI: GitHub Actions

Structured QA artefacts based on the shopping-list-app, demonstrating applied ISTQB principles in a real project.

Includes:

• Risk-based test strategy and prioritisation
• Traceability mapping (requirements → tests)
• Test design (EP, BVA, negative testing)
• Exploratory testing notes and defect reporting
• Severity and priority justification
• Regression planning

Concept: Applying structured QA methodology in a practical, production-style context.

Backend REST API built with Java, Maven, and PostgreSQL, focused on service-layer architecture and data modelling.

Designed to explore structured backend development with an emphasis on correctness, validation, and incremental releases.

Focus areas:

• Layered architecture (controller → service → persistence)
• Relational data modelling and query design
• API design and endpoint structure
• Incremental feature development (v0.x releases)

Current status:

• Functional API implementation complete (v0.2)
• QA validation and automated testing planned next

Tech: Java, Maven, PostgreSQL
Testing: API testing (Postman, early-stage)

Python CLI utility with a clearly separated, testable core focused on deterministic text processing.

Quality:

• Business rule validation and edge case handling
• Isolated unit testing of core logic
• Deterministic output verification

Tech: Python
Testing: pytest
CI: GitHub Actions

JavaScript web utility focused on input validation, usability, and accessibility.

Quality:

• Structured manual testing aligned with ISTQB principles
• Accessibility-aware validation and user feedback
• Edge case handling and input normalisation

Tech: JavaScript, HTML, CSS, Bootstrap

• Risk-based test design and prioritisation
• Manual, API, and automated testing (unit, integration, E2E)
• Test design techniques (EP, BVA, negative testing)
• Exploratory testing and failure-mode analysis
• Structured defect reporting with clear traceability
• Accessibility-focused testing
• CI-integrated regression thinking
• Applying ISTQB principles in practical development environments

Languages: Java, Python, JavaScript, TypeScript, C++, SQL
Backend: REST APIs, service-layer structure, authentication, data validation
Databases: PostgreSQL, MongoDB
Testing: Playwright, Jest, Supertest, React Testing Library, pytest
Tools: Git, GitHub, GitHub Actions (CI), Docker, Maven, Postman, Linux

• Expanding test automation across backend and API layers
• Developing backend systems in Java with a focus on testability
• Bridging development and QA to support end-to-end quality
• Strengthening C++ skills with a focus on embedded systems and low-level performance

• Structured, analytical, and detail-oriented
• Strong focus on reproducibility and reliability
• Comfortable working from specifications and acceptance criteria
• Clear and concise in technical communication and documentation
• Collaborative and pragmatic in problem-solving
