On a 120-stack AWS Organization, CloudFormation StackSets for platform baseline plus CDK for app teams cut org-wide guardrail rollout from 6 weeks to 2 — with Application Composer for spikes and Blocks for greenfield TypeScript only at preview.

For a fintech SaaS (6 prod databases, ~$14k/mo RDS line), scoping in-house DBA for schema + MSP for 24/7 paging cut on-call from 22 to 9 hrs/mo — Aurora Serverless v2 min ACU tuning handled tier-2 first.

For discrete manufacturing (~850 OPC-UA tags, 12 lines), Greengrass + IoT SiteWise anomaly detection moved OEE from 61% to 74% in 90 days — unplanned downtime −18% without replacing MES.

For a mid-market software estate (~280 VMs, $340k/yr Broadcom renewal), splitting 60% MGN rehost + 25% EVS relocate + 15% replatform cut parallel-run from 22 to 16 weeks — without forcing one hypervisor strategy.

On a B2B SaaS crossing Series A (~$18.5k/mo AWS), running the funding-stage gate checklist before the B round cut diligence prep from 11 weeks to 4 — Organizations split, WAF, and SOC2 evidence path without re-platforming.

Before a partner-led WA Review, a fintech workload with 23 open HRIs spent 6 weeks on unfocused fixes; after the readiness checklist and HRI cap of 5 for 90 days, the next milestone dropped High Risk items from 23 to 7 in one review cycle.

On a 40-account AWS Organization, platform baseline via CloudFormation StackSets (Hooks, GuardDuty enroll) plus app teams on Terraform/OpenTofu cut org-wide guardrail rollout from 9 weeks to 3 — without forcing one tool for everything.

On a multi-domain retailer (~4,200 Glue tables, 11 AWS accounts), publishing a stewardship RACI plus SageMaker Catalog subscriptions cut mean time-to-data-access from 19 days to 4 days — without replacing Lake Formation enforcement.

For a product SaaS (~12 production nodes, 3 clusters), EKS Auto Mode cut internal K8s ops from 80 to 35 hours/month at similar compute spend — partner MSP quote was $6,500/mo on top for 24/7 paging alone.

For a specialty retailer (~380 stores, 2.4M loyalty members), S3 Tables Iceberg silver plus Kinesis cart events cut dashboard refresh from 26 hours to 22 minutes — conversion reporting error dropped from 11% to 2%.

For a mid-market 3PL (~2.1M shipments/yr, OTIF 82%), layering AWS Supply Chain on ERP ingest plus Location Services fleet tracking moved ETA accuracy from 71% to 87% in 90 days — without replacing Manhattan WMS.

On a fraud-scoring team (~450 RPS peak, ml.g5.2xlarge), inference components plus April 2026 capacity-aware instance pools cut endpoint provisioning failures from 6 retries to 0 — p99 held at 68 ms through a g5→g6 fallback event.
