“Releases are slow, manual and feared”
DevOps & CI/CD
“A migration is looming and nobody trusts the map”
Cloud architecture & migration
“Incidents recur and recovery depends on heroes”

Directional read
≈2 nodes of conservative headroom
Requests are pinning ~35% more capacity than the workload uses. The real number is conditional on placement, DaemonSets, AZ spread, disruption budgets and autoscaling lag — but the gap is worth a look.

Load-test evidence
Built for traffic that does not arrive gradually
120,000+
concurrent-user load-test capacity
- System
- Real-time sports platform — AWS · Kubernetes · Redis · MongoDB
- What was breaking
- Fixed capacity and direct DB reads; latency rose at match peaks
- The engineering
- Workload separation, Redis cache layer, autoscaling calibrated via staged load tests
- What held
- p95 stable through surges · 99.97% peak-event availability
E-commerce technology
Production result
Preparing a commerce platform for four times normal transaction volume
4.2×
normal transaction volume supported
- System
- Commerce platform — GCP · AWS · Kubernetes · multi-cloud
- What was breaking
- Peak-season demand outgrew infrastructure, rollback and observability
- The engineering
- Re-architected deployment, observability, rollback and capacity testing
- What held
- 99.98% seasonal availability at 4.2× normal volume
B2B SaaS
Production result
Reducing cloud expenditure without reducing operational confidence
31%
lower monthly cloud spend
- System
- B2B SaaS estate — Azure
- What was breaking
- Spend rising faster than usage; no allocation or ownership
- The engineering
- Utilisation analysis, rightsizing, scheduling, commitments, tagging, governance
- What held
- Performance held while monthly spend fell 31%
Flagship engagement · ANS Commerce
- The problem
- Fragmented three-cloud estate; VM-heavy workloads and manual change slowing delivery and driving cost
- The engineering
- Terraform foundations, CI/CD on Jenkins, EC2 → GKE re-platforming, cost governance
- The outcome
- ~30% lower cost in the verified scope, on one governed platform
