We do the AWS work.
Then we hand you the keys.
Senior AWS engineers, project-based. We deliver platform builds, migrations, IaC modernization, and cost reviews — each with fixed scope, a clean handoff, and no lock-in.
Engagements,
not retainers.
Four shapes of AWS work — each one fixed-scope, delivered by senior practitioners, and handed off so your team owns it. No lock-in.
Greenfield Platform Builds
Multi-environment AWS infrastructure from scratch, defined entirely in Terraform. VPC, compute, serverless, CI/CD, observability, security — production-ready in weeks, not months.
IaC Modernization
Refactor sprawling Terraform or CloudFormation into something your team can actually maintain. Untangle dependencies, fix drift, modularize — and leave behind a codebase that's safe to change.
Cloud Migrations
On-prem to AWS, other clouds to AWS, or AWS account consolidation. Discovery, dependency mapping, phased cutover plan — and zero downtime where it matters.
Cost & Architecture Reviews
Audit your AWS spend and identify quick wins, or run a formal Well-Architected review across security, reliability, performance, and cost. Action-ready output, not a deck.

module "monitoring" { source = "./modules/observability" }
# Every environment. Every service. Every deployment. Automated.
From zero to production
in four steps.
A proven framework refined across multiple engagements. No guesswork. No scope creep. Just results.
Discovery
We map your application architecture, team workflows, and scaling requirements. One week, clear deliverable: an infrastructure blueprint.
Build
We deploy our battle-tested Terraform framework, customized to your stack. Dev, staging, production — fully automated from day one.
Handoff
Your team gets the codebase, documentation, runbooks, and a live walkthrough. You own everything. No lock-in. Full transparency.
Support
Optional 30/60/90-day support window after handoff for transition questions and minor adjustments. After that, your team runs it independently — that's the goal.
Infrastructure expertise
without the overhead.
Senior AWS expertise, scoped to your project. No permanent hire to make. No Big Four overhead. We come in, do the work, hand it over, and go.
Infrastructure as Code
Nothing is configured manually. Every resource is defined in Terraform, version-controlled, and reproducible. No snowflake servers. No click-ops.
Not Months
Our framework is pre-built and battle-tested. We customize for your stack — we don't start from scratch. Most engagements ship in 4–8 weeks.
Zero Lock-in, By Design
Most consultancies want to live in your AWS account forever. We don't. We build it right, train your team, and hand it over — so you're never dependent on us.
