You might need this if...

Six reasons people come to us. If any of these sound familiar, we should talk.

You're starting on AWS

You need an architecture that won't need rewriting in 12 months — designed by someone who's seen it scale.

You're already on AWS but it's expensive or unstable

Cost is creeping up, performance is patchy, and nobody on the team is sure what's safe to change.

You want to build AI on AWS specifically

You need Bedrock, agents, RAG pipelines and grounded LLMs deployed properly inside your existing AWS account.

You need help with serverless, Lambda, API Gateway, DynamoDB

These are the services we built. We know the failure modes, the limits, and the right patterns — not the textbook ones.

You need an AWS migration done properly

Lift-and-shift gets you 40% of the value. We help you design what to actually migrate, refactor, or rebuild.

You want a senior engineer on tap

Not a junior consultant from a five-person team. Real architectural guidance from people who've worked inside AWS.

Services

What we offer

Four core service areas. All delivered by senior engineers, all built on AWS, all yours to keep.

AWS Architecture & Migration

Design and deliver scalable, secure AWS architectures. Existing workloads migrated, refactored, or rebuilt for cloud-native. Multi-account strategies, landing zones, networking, and security baselines done right.

AWS Organizations
Control Tower
Transit Gateway
CloudFormation
Serverless Development

Lambda, API Gateway, DynamoDB, Step Functions, EventBridge. Production-grade serverless built by the engineers who contributed to the AWS CLI, CDK, SAM, and Amplify.

API Gateway
DynamoDB
Step Functions
AI on AWS

Bedrock, agents, RAG pipelines, Knowledge Bases, Amazon Transcribe & Lex. Generative AI built natively on AWS — not bolted on. Includes prompt engineering, evaluations, and human-in-the-loop controls.

Cost Optimisation

Spending too much? We audit your AWS account, identify the 20% of resources causing 80% of the bill, and re-architect or right-size them. Typical savings: 30–60%.

Why ex-AWS

Most AWS consultants passed the exam. We helped build the platform.

AWS certifications prove you've learnt AWS. They don't prove you've built AWS. Our engineers have contributed code to AWS CLI, CDK, SAM, and Amplify. We've presented at AWS re:Invent and AWS Summits. We've worked alongside the service teams shipping the products you use every day.

That depth shows up in the work. We don't guess at AWS best practices — we know which patterns scale, which fail quietly, and which are already obsolete. We've seen the edge cases the documentation doesn't cover.

Client testimonials

What clients say

The team helped us architect our Next.js application on CloudFront and S3. Their expertise and guidance, including building demos, was invaluable in helping us understand the best approach and provided significant architecture simplification.

Who this is for

Who we work with

We're a good fit if...

You have an AWS account already, or you know AWS is the platform you want to build on

You need senior architectural guidance, not junior implementation hands

You want infrastructure-as-code (CloudFormation, CDK, or SAM) — not click-ops

You want a team you can call when things break, not a faceless support ticket queue

You're ready to move within the next 1–3 months

We're probably not the right fit if...

You have no AWS in your stack and no plans to adopt it — we're AWS-first (though we work with hybrid and multi-cloud setups where AWS is part of the picture)

You need 24/7 enterprise managed services with a 50-person account team

You want a low-cost offshore implementation team

You want to build in-house and just need a training course

Start with a conversation, not a commitment

Book a free 30-minute discovery call. You'll speak directly with our team — not a junior account manager. By the end of the call you'll have a clear picture of whether we're the right fit and what a first AWS engagement could look like.
