The challenge.
Every major sale event was a crisis. The site slowed, froze, or fell over in the first hour of a promotion, leaving hundreds of thousands on the table. A monolith on a handful of dedicated servers couldn't scale horizontally, and a two-year-old migration plan had stalled out of fear of breaking a working business.
How we worked
The ADAS framework, applied to this build.
Architect
Audited the application, traffic patterns, and database hotspots, then designed a strangler-pattern migration that prioritised the highest-load services, with risk and rollback planned at every step.
Deliver
Moved priority services to managed cloud infrastructure while the monolith kept serving the rest, re-architected the database layer with read replicas and caching, and ran the next major sale on the new stack.
Advise
Sat with their leadership through architecture decisions and stayed available as their platform partner, interpreting cloud bills, advising on vendor lock-in, and shaping their in-house DevOps capability.
Scale
Set up autoscaling tuned to their actual sale-day profile, not generic templates. The platform now absorbs spikes automatically, and new markets and channels plug in without infra projects.
The outcome.
The next flash sale handled 18× the previous peak with zero downtime. Page loads improved even at normal traffic, and monthly infrastructure cost dropped now that they no longer over-provisioned for sale days.
Cloud migration isn't a project. It's a sequence of business decisions about what to move first, what to leave alone, and what to rebuild on the way.
