Services we provide
From the first line of code to the pager at 3 a.m.
DevOps & cloud platforms
AWS, GCP and Kubernetes environments designed for rapid, safe deployments so your features reach production the day they are ready.
CI/CD & release automation
Pipelines, infrastructure as code and environment parity that turn releases into a routine, not an event.
SRE & observability
Monitoring, alerting and incident practice that keep uptime measurable and on-call humane.
Technical audits
An honest read of your architecture, technical debt and cloud spend, with a prioritised plan you can actually execute.
Team augmentation
Engineers who integrate into your workflows and rituals, not a black box agency sitting on the other side of a wall.
How we work
Transparent by default.
Shared boards, shared repositories, shared metrics. You see the same numbers we do — velocity, uptime, cloud spend — from week one.
- 01
Discovery
Two weeks to map goals, constraints and the current system. You leave with a scope, a budget and a risk list.
- 02
Foundation
Architecture, environments and pipelines first, so the first feature ships on the same rails as the hundredth.
- 03
Delivery
Two-week iterations, demo every cycle, production deploys whenever a slice is done.
- 04
Run
Monitoring, SLOs and cost control. We stay accountable for the system, not just the commit history.
Selected work
Systems in production, not slide decks.
