[ The Problem ]
Where the business was stuck.
Global tax SaaS bogged down by slow releases, audit friction and ballooning Azure spend.
[ Key Challenges ]
- ▸Monthly release cadence blocked product growth
- ▸Audit evidence assembled manually every quarter
- ▸Uncontrolled Azure spend from oversized SQL and VM footprint
Our approach
How we engineered
the outcome.
STEP 01
Refactored monolith into 12 domain services on AKS
STEP 02
GitOps delivery with ArgoCD, policy-as-code with OPA/Gatekeeper
STEP 03
Cost governance model with tag-based showback per tenant
[ Solution highlights ]
Delivered — measured — in production.
- ✓Release cadence moved from monthly to twice-weekly
- ✓Audit evidence generated on-demand from pipeline metadata
- ✓Azure SQL right-sized and moved to elastic pools
