No engineering team?
You have a business to run and software that must ship and stay reliable. We act as your engineering team — designing, building, and running the platform so you can move faster without hiring an internal department.

Founders without a technical co-founder
You know the market and the customer problem. We bring the technical leadership to turn that into a scalable product, acting as your fractional CTO from idea to launch.

Your team can ship, but you've hit a hard problem in cloud, data, or AI. We bring in senior specialists to unblock delivery fast, then hand back clean, documented systems your team can own.

Six core specialisms, one standard: senior engineers accountable for outcomes.
01 / CLOUD
Cloud architecture & AWS
We design AWS platforms that are secure, scalable, and cost-aware, from serverless APIs to event-driven systems. Everything is defined as code (CDK, Terraform) so environments stay reproducible and reliable.
02 / DATA
Data engineering & analytics
We build data platforms that turn raw events into decisions: data lakes, production ETL/ELT (Glue, PySpark, Airflow, dbt), and BI layers in Power BI or Looker.
03 / AI
AI & machine learning
We apply AI where it creates measurable value: recommendations, support automation, and LLM-powered workflows built on Bedrock, SageMaker, and modern tooling.
04 / FINOPS
Cloud cost optimisation & FinOps
We reduce cloud spend without hurting reliability. With FinOps practices and automated cost controls, we've delivered cost reductions up to 40% while improving performance.
05 / MODERNISATION
Platform modernisation
We modernise legacy systems by breaking monoliths into maintainable services and serverless components that are easier to ship, scale, and operate.
06 / PRODUCT
Full-stack product development
We build products end to end: backend APIs (Python, Go, Node/TypeScript) plus modern frontends (React, Svelte), with senior engineers owning delivery.
A track record at real scale
Our founding team has spent 15+ years building production systems at scale across cloud, data, and AI.

Modernising an analytics platform
Challenge
A legacy SQL Server warehouse was slow and expensive to run.
What we did
Replatformed to an AWS data stack (S3, Athena, Redshift Serverless) using Infrastructure-as-Code.
Result
Cut costs by 40% and improved query speed 5x.
Data pipelines for 100+ enterprise customers
Challenge
Needed reliable analytics across a large multi-tenant customer base.
What we did
Built multi-tenant ETL pipelines processing ~10 million events per month, with dashboards delivered in Looker.
Result
Enabled self-service analytics for 100+ enterprise customers and tens of thousands of field users.
Legacy monolith to microservices
Challenge
A legacy PHP monolith slowed delivery and blocked scaling.
What we did
Rebuilt as microservices with a Python/Django backend, React SPA, and serverless workloads on AWS Lambda.
Result
Shortened release cycles and created a platform ready for growth.
Senior engineers from strategy to production
STEP 01
Understand
We start with the business outcome, not a feature list. In a short discovery sprint, we define the problem, constraints, and success metrics.
STEP 02
Build
Our senior team designs and ships with CI/CD, Infrastructure-as-Code, and observability from day one.
STEP 03
Run & hand over
We run the platform in production and hand over clean, documented, well-tested systems your team can own with confidence.
No offshore handoffs. No junior teams learning on your budget. The people you meet are the people who build and run your system.
A small team of senior engineers
Busyminds Digital was founded on a simple belief: most businesses don't need a large agency. They need a small team of senior engineers who care about outcomes.
We're deliberately small. You work directly with the engineers doing the work — no account managers, no layers, no surprises.
Senior by default.
Every engagement is led and delivered by engineers with 15+ years in production.
Small and accountable.
You work directly with the people doing the work — fast decisions, no layers.
Cloud-native and cost-aware.
AWS specialists who treat your cloud bill like our own.
We leave it better.
Documented, tested, and maintainable — built so you're never locked in to us.
