Multi-account architecture, SCP boundaries, account vending, Identity Center (SSO), Service Catalog for managed templates.
Senior engineering · AWS
Senior AWS engineering for production systems.
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
AWS in production is a different problem than AWS on a laptop.
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.

Outcome-led SOW
Where AWS ships
6 sub-areas, grounded in shipped engagements.
Specific applications of AWS we’ve built and operate. Every example below maps to a real engagement, not a bullet on a stack-card.
01 02 EKS + Container platforms
EKS clusters with Karpenter autoscaling, Fargate for serverless containers, ECR + image scanning, AppMesh / Istio service mesh.
03 Serverless + event-driven
Lambda + Step Functions, EventBridge, SQS / SNS, Lambda layers for shared code, Lambda PowerTools for observability.
04 Networking + security
Transit Gateway, PrivateLink, RAM-shared resources, GuardDuty, Security Hub, Inspector, KMS / Secrets Manager hygiene.
05 Data + analytics
Aurora Postgres / MySQL, RDS, DynamoDB, Redshift, Glue + Athena, S3 + Lake Formation. Data-residency and compliance frame.
06 FinOps + cost optimization
Cost Explorer + Cost & Usage Reports, savings plans, spot / preemptible workloads, right-sizing, autoscaling tuning. Typical 30–40% Q1 reduction.
Stack depth
The AWS ecosystem, owned.
Frameworks, libraries, and runtime tools the bench has shipped in production. Not a CV-skim, a working depth.

Engagement models
Three ways to engage AWS engineers.
We don’t bill hourly contractors. Engagements run against outcomes, choose the shape that matches the work.
See engagement models- 01
Fixed-scope
Defined deliverable, fixed price
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.
- 02
Embedded squad
Senior product team, ongoing
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.
- 03
Managed services
Steady-state operations
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.

FAQ
Questions buyers ask.
Everything below also appears in the proposal and the SOW: no surprises after signing.
AWS, Azure, or GCP?
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.
EKS or ECS for new container workloads?
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.
Is this staff-aug, or is it engineering-led delivery?
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.
What seniority floor are we talking about?
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.
How does pricing work?
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.
Where are your engineers based?
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.
Will the engineers I see in the proposal be the engineers shipping the work?
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.
Talk to a AWS lead
Senior AWS engineering, accountable from kickoff.
Bring the workload: we’ll bring a senior engineer plus the practice lead most relevant to the work. 30 minutes, no obligation, no junior reps.
