The challenge
A single monolith ran the whole product — expensive to run, slow to deploy, and impossible to scale one part without scaling all of it. Every release carried downtime risk.

The approach
A strangler-fig migration: we peeled services off the monolith one bounded context at a time into an event-driven architecture, all infrastructure as code, with a zero-downtime cutover behind feature flags.
- stage_03 · ship
The outcome
63% lower infrastructure cost, independent scaling per service, and multiple safe deploys a day — all delivered without a single minute of planned downtime.
