Full-Stack Product Engineering | Angular, Payments & UI
November First
Customer-facing Angular and TypeScript development alongside senior ownership of payment, foreign-exchange, banking-integration, API, and FIX functionality.
Full-stack scope
I worked across the customer-facing product and the underlying payment engine. The platform supported international business payments, currency conversion, quotes, real-time pricing, banking integrations, and payment workflows.
Customer-facing Angular application
I translated business and marketing requirements into production interfaces using Angular, TypeScript, JavaScript, HTML, and CSS. I implemented new UI functionality, fixed frontend defects, improved responsive behavior, and refined interaction quality while working with stakeholders to determine how requested features should look and behave.
Engineering and testing
I owned important functionality using C#, .NET/ASP.NET, FIX/QuickFIX, APIs, MongoDB, and SQL technologies. I tested the frontend and backend through automated, integration, end-to-end, and manual testing, and documented payment-engine behavior for team knowledge transfer.
Business impact
Customer-requested currency-exchange functionality implemented through FIX contributed to roughly 15% sales growth.
