Established as a Major Payment Institution in Singapore, Walletory offers features like multi-currency support, API-driven payouts, and instant peer-to-peer transactions, catering to the needs of the global economy.
As the lead developer, I spearheaded the design and development of Walletory’s enterprise-level fintech applications. My responsibilities included architecting scalable APIs for the e-wallet application, designing complex databases with over 200 interconnected tables across four databases, and integrating third-party APIs such as SMS gateways, fraud detection services, and email delivery platforms.
I ensured code quality and maintainability by implementing best practices like SOLID principles, TDD, and DRY. Utilizing static code analysis tools such as PHPStan and PHP Insights, I maintained high coding standards. Additionally, I established continuous integration and deployment pipelines, conducted code reviews, and performed code refactoring to enhance system performance and scalability.
Walletory’s platform enables businesses to integrate global payment solutions seamlessly, offering features like local payment collection, instant payouts, and multi-currency bank accounts. For individual users, Walletory provides an easy-to-use wallet for secure and fast transactions, supporting the thriving sharing economy.
Through my leadership and technical expertise, Walletory has become a robust and scalable digital wallet platform, facilitating secure and efficient financial transactions for users around the globe.
