Breaker

Introduction

Breaker came to Volume after their previous development team delivered an MVP that wasn't ready for the real world. The product had launched, but it couldn't scale, the UX didn't meet industry standards, and the underlying architecture had fundamental limitations that no amount of patching would fix. Breaker needed a team that could assess the damage, make hard calls, and rebuild the platform into something production-worthy.

Challenge

The MVP inherited from the prior team was built on shortcuts. The send architecture relied on cron jobs, creating hard bottlenecks that couldn't handle growing volumes. The frontend was functional but failed to meet UX compliance standards expected in ESP software. More critically, the codebase lacked the architectural foundation to support the features Breaker needed to compete: reliable campaign management, audience segmentation, and performance analytics at scale. The previous team didn't have the domain knowledge to understand what production-grade ESP infrastructure actually requires.

Approach

Volume started with a full design audit and code audit to separate what was salvageable from what needed to go. The answer was most of it. The team refactored the codebase onto a modern tech stack and architected a new backend from scratch. The send pipeline was rebuilt from cron-based batch processing to a Redis background job architecture, eliminating the throughput ceiling entirely. The frontend was redesigned to meet UX compliance standards, giving Breaker a platform that looked and performed like a mature product rather than a rushed MVP.

Results

The rebuilt platform now handles over 1.5 million sends per week with less than 0.1% downtime since going to production. Send capacity increased by 200x compared to the original MVP. The redesigned interface brought the product up to the standard Breaker's customers expect from a professional ESP tool.
