World Tone
Worldtone is a globally distributed social networking ecosystem engineered to support high-volume, real-time interaction between users across different continents. My primary role was designing and building the backend architecture capable of handling millions of concurrent socket connections with minimal latency while ensuring message delivery guarantees, fallback retries, and data consistency across distributed servers.

I developed the complete real-time communication engine using Socket.io with a custom event-pipeline architecture. This system supports one-to-one messaging, group conversations, media transfer, message delivery states, encrypted signaling for video calls, and presence tracking. I also implemented message synchronization logic to ensure conversations remain consistent across multiple user devices.
With its robust AI-powered features and user-friendly interface, Alter has redefined how businesses generate interest, engage with their audience, and streamline their SaaS growth.
A core feature of Worldtone is the Tinder-style swipe system combined with intelligent match discovery. I built the geospatial engine using MongoDB’s geo queries to calculate real-time distance between users, apply preferences such as age, gender, and interests, and run a ranking algorithm that optimizes match quality based on engagement signals, recency, and proximity.
The platform includes a full-scale international payments layer. I integrated Stripe, WeChat Pay, and AliPay to support users from Asia, Europe, and the Middle East. I developed secure payment endpoints, webhook listeners for subscription life-cycle events, fraud detection checks, and multi-currency support for purchases and premium features.
W The backend maintains large-scale resilience using Node.js, Express, and MongoDB. I implemented optimized data models, compound indexes for high-speed querying, and horizontal scaling strategies. Every endpoint was engineered for high throughput with caching layers, pagination rules, and optimized aggregation pipelines.
