01. Overview
EarnBuddy is a microservices-based SaaS marketplace that connects content creators, gig seekers, and task commissioners. Built with Node.js, Express, and Redis pub/sub, it delivers sub-100ms API response times even during peak campaigns.
The Problem
Traditional freelancing platforms suffer from sluggish messaging, delayed escrow tracking, and excessive database overhead caused by un-optimized relational queries on volatile task queues.
The Solution
Implemented domain-driven REST APIs backed by MongoDB aggregation pipelines and Redis caching layers, combined with Socket.IO for instantaneous status notifications and chat.
