Context

7-month permanent contract at PaySystem, a Luxembourg startup publishing a SaaS payroll-management platform. Contributed to the development of frontend and backend features, as well as product maintenance.

My role: junior fullstack developer, first real experience with Angular in a business setting.

Key achievements

Employee-onboarding stepper

Development of an Angular Material stepper component letting clients (HR firms, executives) add their employees through a multi-step form. Smooth navigation between pages, incremental data entry, per-step validation.

Technical challenges: smooth UX on a multi-step form, complex state management across steps.

Impact: intuitive interface appreciated by clients, fewer input errors thanks to per-step validation.

Government-site scraping (payslip pre-fill)

Development of an automated scraping module to gather the data required to generate payslips from a loosely structured government website. Feature additions and optimization of existing code.

Technical challenges: first exposure to PHP and Puppeteer, poorly structured government website.

Impact: significant time savings for users, a more seamless experience than manual entry on the government site.

Takeaways

• First real exposure to Angular in a business context (with Angular Material)
• Development of REST APIs with Node.js and Express
• First production unit tests
• Kanban-based collaboration
• Early reflection on clean code and optimization
