Scaling to 100K Users at the Crohn's & Colitis Foundation
Fault-tolerant microservices for a mission-critical non-profit platform
Outcome
100K+ users · 20–30% faster APIs · 25–40% more test coverage
The Problem
The platform had tightly coupled services, slow API response times, and insufficient test coverage — creating reliability risks for a user base that depended on accurate health data.
The Approach
- 1
Decomposed monolith into fault-tolerant microservices — enabled 30–40% faster independent deployments.
- 2
Optimised RESTful APIs by reducing payload sizes, cleaning endpoints, and removing redundant round trips.
- 3
Wrote comprehensive unit and integration tests — raised code coverage by 25–40%.
- 4
Addressed critical security vulnerabilities flagged in a code audit.
The Result
Platform reliably served 100K+ users with 20–30% faster API response times, fewer UI errors, and a meaningfully improved security posture.
