Keeping the lights on for a 20-year-old certificate platform

Digital trust infrastructure provider

10x performance improvement · 95-100% fewer deployment incidents · Weeks to hours: feature delivery · 20+ services containerized

The problem

A 20-year-old certificate issuance system was still the revenue engine of the business. Deployments were manual and risky, engineering and operations miscommunicated constantly, and the platform needed modernization for compliance and security without any service interruption.

The approach

Containerized 20+ services and introduced zero-downtime deployment pipelines. Created shared testing and QA environments that eliminated miscommunication between engineering and operations. Championed secure-by-design practices across legacy codebases and migrated all applications and repositories to modern development workflows.

The outcome

Legacy services saw a 10x performance improvement. Deployment-related incidents dropped 95-100%. Feature delivery went from weeks to hours. All ~20 applications were fully migrated to modern workflows without service disruption.
