Software developer · PHP & VueBasel region, Switzerland

I build Vue interfaces for complex business processes, the PHP backends and integrations behind them, and own the automated release tests. On the side I develop and run my own web applications where design and code come from one hand. Available from 1 December 2026, full-time.

Experience

since 11/2021zvoove Switzerland AG

Application developer (full-stack)

Designed and built Vue interfaces for complex business processes and developed the associated PHP endpoints, including digital document and signature workflows.
Shared responsibility for integrations and data synchronisation: implemented requirements in PHP and SQL, investigated root causes and resolved faults.
Built a CSV export for a product migration as part of a team: mapped data from multiple databases to the target format, implemented validation and fixed export failures with large or incomplete datasets.
Played a major role in developing and maintaining a Cypress suite of around 30 extensive release tests. Ran tests, analysed failures and fixed issues or coordinated their resolution.
Extended API endpoints for an AI-assisted application and reviewed API contracts, tests and error handling.
Ongoing Cypress-to-Playwright migration: built a parallel test suite and ported tests; adoption in the regular release process is in preparation.
