Web Applications
A real-time financial presentation platform with live audience interaction, integrated payments, and SSO authentication.
What it does: Enables live financial presentations with real-time audience synchronization, secure payments, video streaming, and work hours tracking. How it was built: Java + Spring Boot with StompJS WebSockets for real-time communication, Next.js + React frontend using Atomic Design, Stripe for payments, AWS Cognito for SSO, JW Player for video, PostgreSQL, and Docker. What I learned: Engineering a real-time WebSocket communication layer at scale; integrating multiple mission-critical third-party services (Stripe, Cognito, JW Player) within a single platform; applying Atomic Design principles in a data-heavy UI.
