Contributed to the development and quality assurance of Laravel/React applications within an Agile product team. Developed and maintained end-to-end test automation with Playwright, covering the main comparison and withdrawal flows and more than 16 key use cases. Designed and implemented a dedicated Playwright testing setup, including test structure, reusable components and automated execution. Optimized test execution by analyzing and reducing redundant test cases, improving the overall runtime of the test suite. Investigated and fixed frontend-related issues affecting test stability, including a memory leak impacting execution. Integrated automated tests into CI/CD pipelines, with scheduled daily execution and automated Slack notifications including test statistics and reports. Worked closely with developers and stakeholders to identify regressions and improve application reliability before production. Contributed to code quality and maintainability through structured test coverage, debugging and continuous improvement of the automation architecture. Used Git, CI/CD, Docker, Laravel, React, Playwright and Slack within the development workflow.

Developed and maintained high-traffic web applications using PHP, Symfony and TYPO3, working across the full life cycle from technical design to deployment and production support. Contributed to major TYPO3 migrations from v10 to v12.4 and subsequently v13, including compatibility work, refactoring and modernization of existing components. Designed and implemented a Symfony-based cache publishing system using workers, Messenger, APIs and Nginx to generate and serve static HTML content efficiently.

Designed and integrated REST APIs and headless API solutions, including an API proxy between systems. Worked on complex content and recommendation-related APIs involving relationships between products, categories and combined recommendations, consumed by TYPO3 content components. Implemented unit and integration tests around critical business logic and API functionality to improve reliability and maintainability. Worked with MySQL, Docker, Jenkins and Datadog for development, CI/CD and production monitoring. Investigated production issues using monitoring and logs, and contributed to performance improvements involving caching, API response times and database interactions. Participated in technical discussions, code reviews, refactoring and architectural decisions with other developers. Worked closely with business requirements and content teams to translate functional needs into maintainable technical solutions. Contributed to reducing technical debt through modernization, refactoring and progressive migration of legacy TYPO3/Symfony components.
