Frontend Developer Apr 2021 – Present
Probegin (E-commerce, Hybrid)
• Led frontend development for a Dutch ticketing & merchandise platform, overseeing responsive UI implementa-
tion, complex business logic, and UX optimization for high-traffic environments. .
• Engineered an interactive stadium seating map, optimizing canvas/SVG rendering logic. This resulted in a
significant boost in frame rates and eliminated interaction lag during peak sales periods. .

interface across the entire application.

Saga with Redux Toolkit. These initiatives reduced the codebase size, cut technical debt, and increased feature
delivery speed by 50% .
• Mentored and scaled a team of 2 junior developers through structured code reviews and architectural guidance,
successfully accelerating their transition to independent feature owners within 4 months.
• Resolved critical cross-browser scaling and rendering issues through deep-dive debugging of CSS/Layout engines,
ensuring a consistent user experience across all devices and legacy browsers.
