AWS Organizations + Control Tower
Multi-account architecture, SCP boundaries, account vending, Identity Center (SSO), Service Catalog for managed templates.
Senior engineering · AWS
AWS architecture and engineering — multi-account, multi-region, IaC-driven, FinOps-aware, and the operating discipline that defends an SLO instead of just tracking spend.
Why senior, not contractor
Most AWS environments accreted over years — root accounts in production, IAM policies pasted from Stack Overflow, regional sprawl, and a bill that grows 30% YoY without any team able to explain why. Prosigns ships AWS as a managed practice: multi-account organizations with clean SCP boundaries, Terraform / CDK-driven infrastructure, observability calibrated to the on-call's actual questions, and FinOps that trims 30–40% of cloud spend in the first quarter.

Where AWS ships
Specific applications of AWS we’ve built and operate. Every example below maps to a real engagement, not a bullet on a stack-card.
Multi-account architecture, SCP boundaries, account vending, Identity Center (SSO), Service Catalog for managed templates.
EKS clusters with Karpenter autoscaling, Fargate for serverless containers, ECR + image scanning, AppMesh / Istio service mesh.
Lambda + Step Functions, EventBridge, SQS / SNS, Lambda layers for shared code, Lambda PowerTools for observability.
Transit Gateway, PrivateLink, RAM-shared resources, GuardDuty, Security Hub, Inspector, KMS / Secrets Manager hygiene.
Aurora Postgres / MySQL, RDS, DynamoDB, Redshift, Glue + Athena, S3 + Lake Formation. Data-residency and compliance frame.
Cost Explorer + Cost & Usage Reports, savings plans, spot / preemptible workloads, right-sizing, autoscaling tuning. Typical 30–40% Q1 reduction.
Stack depth
Frameworks, libraries, and runtime tools the bench has shipped in production. Not a CV-skim — a working depth.
IaC
Compute
Networking + security
Data + analytics
Observability + ops
Engagement models
We don’t bill hourly contractors. Engagements run against outcomes — choose the shape that matches the work.
See engagement modelsFixed-scope
When the deliverable is clear and the scope is bounded — an MVP, a migration, a discrete platform build. Senior engineering against a written outcome, not against a body count.
Embedded squad
When the work is product-shaped and the cadence is continuous. A senior pod (engineering + design + PM as needed) embedded into your team, with the practice lead co-piloting from HELM.
Managed services
When the system is running and needs ongoing engineering ownership — operations, SLO defense, release management, security and compliance evidence. Monthly retainer against a published SLA.
Selected work
Financial services
Standardized Terraform modules, multi-account Organization with SCP boundaries, shared EKS clusters with multi-tenant namespaces, and SLO dashboards per service. FinOps review cut steady-state spend by 37% in the first quarter.

FAQ
Everything below also appears in the proposal and the SOW — no surprises after signing.
All three are in our active portfolio. AWS for breadth and primary footprint; Azure when Microsoft enterprise integration is the spine; GCP for data + AI workloads or where the customer's existing footprint is there. Multi-cloud only when the workload genuinely demands it — we don’t recommend multi-cloud as a default because the operating tax is real.
ECS / Fargate for steady-state containerized services where Kubernetes complexity isn’t earning its keep. EKS when you need cluster-level multi-tenancy, custom controllers, or Kubernetes-native ecosystem (operators, CRDs, Helm charts). We’ll tell you which fits — Kubernetes is a real operating tax.
Engineering-led delivery. We don't bill hourly contractors against your JIRA board. Every engagement runs against a defined outcome with a senior engineer accountable from kickoff to operating cutover. If you genuinely need staff-aug — discrete bodies, your management, hourly rates — we'll be honest and route you to a partner that fits.
G6 minimum (six-plus years in their craft) on every billable hour. Department leads are G9 or G10. We don't flex juniors onto the bench mid-sprint, we don't subcontract to delivery centers, and we don't dilute senior rates with mixed staffing. The bench in the proposal is the bench in production.
Three engagement models published at /engagement-models/. Fixed-scope for defined deliverables, embedded squads for ongoing product work, managed services for steady-state operations. Rates depend on seniority, engagement length, and region. Discovery + scoping conversation is free; SOWs are written against deliverables, not bodies.
Senior-only across Dallas, Doha, Lahore, and Islamabad. We staff against the engagement's needs (timezone, language, regulatory frame), not against arbitrary regional preferences. Most engagements run with a US/EU-aligned core and a follow-the-sun extended bench when the workload warrants it.
Yes. We name the engineers in the SOW, attach their profiles, and they're on the kickoff. We don't bait-and-switch with senior reviewers and junior execution. If a named engineer needs to roll off the engagement (rare), we surface a replacement from the same seniority tier with explicit handoff.
