B2B Matchmaking Platform
Helped build the frontend for a global B2B matchmaking platform real-time meetings, deal pipelines, and videoconferencing for hundreds of companies at international trade events.
Overview
Every year, large-scale trade events bring African and international businesses together to form partnerships. This platform digitized and accelerated that process giving companies a space to discover matches, schedule meetings, negotiate deals, and conduct video calls, all in one place, in real time.
The Challenge
The platform had to support hundreds of concurrent users during live, high-stakes events with no margin for failure. Meeting scheduling, deal workflows, and videoconferencing all had to work simultaneously in real time with every state change instantly visible to all relevant participants.
My Role
I owned the full frontend matchmaking UI, as well as helped with the meeting lifecycle, deal pipeline, real-time sync via WebSockets, and the videoconferencing module built on AWS Chime SDK. This was the most complex frontend system I'd built, multiple real-time channels, formal state machines, and a third-party SDK integration, all running together.
Architecture Decisions
WebSockets for all real-time state
Used Socket.IO to broadcast state changes (meeting confirmations, deal updates, new matches) to all connected clients — instant sync with no polling.
AWS Chime SDK for video
Chose Chime over raw WebRTC its managed infrastructure handled ICE negotiation, TURN relay, and connection recovery automatically, reducing complexity significantly.
