Experience
Website Redesign: International Asset Management Firm
The solution featured a location selector and flexible jurisdiction toggles for page content and footer fields, ensuring compliance with local regulations and cultural context. I led the development of over 25 reusable content modules, optimized the data architecture for improved performance and scalability, and integrated GDPR-compliant cookie consent management through OneTrust.
The platform delivered a cohesive global brand experience, empowering local teams to manage region-specific content. Throughout the project, I gained a deep understanding of financial markets, including working with CUSIPs. I mastered advanced localization, from region-specific monetary formats to jurisdiction-based content, ensuring accuracy and consistency across all global sites.
