Project Overview

What We Built

TechFlow Solutions relied on a Node.js backend that suffered from severe memory leaks, causing production servers to crash daily during peak load. We provided emergency stabilization, deep memory profiling, and architecture refactoring.

The Challenge

Problem Statement

The platform was losing concurrent user sessions randomly, and CPU usage frequently spiked to 100%, causing massive latency and downtime.

Our Solution

How We Solved It

We conducted heapsnapshot analysis to identify the memory leak in their WebSocket implementation. We refactored the event listeners, implemented Redis for state management, and containerized the application for auto-scaling on AWS.
