# About Vigesimal Tech

> Vigesimal Tech is an engineering consultancy. We go deepest in [AI & data](https://vigesimal.tech/service/ai-data) and [migration & modernisation](https://vigesimal.tech/service/migration-modernisation), with cloud, DevOps and custom software around them, so one small senior team can finish the job.

## What we stand for

Technology fitted to the business, not the other way round. Most of our work starts by working backwards from customer needs or opportunities. We build only what gets you there, hand your team something they can operate, and measure whether it worked.

- **Honest estimates**: If a piece of work is not worth doing, we say so before you pay for it.
- **Senior by default**: The engineers who scope your project are the ones who build it.
- **Small increments**: Working software early and often, so a wrong turn costs days, not months.
- **We run what we build**: We stay on call for our systems, which keeps us honest about how we build them.

## How we deliver

Four phases from first conversation to a system that keeps improving after launch.

1. **Discovery & consultation**: We learn the business, the systems, and what is actually blocking you.
2. **Design & development**: A sequenced roadmap, then working software in increments you can review, tested as it goes.
3. **Solution delivery**: Shipped to production on infrastructure that is monitored from day one.
4. **Continuous improvement**: We stay on to tune, support and extend what we built.

## The practices

- [AI & data](https://vigesimal.tech/service/ai-data): The data platform and the AI that runs on it: pipelines, a warehouse and reporting your team trusts, and agents, assistants and models evaluated before launch.
- [Migration & modernisation](https://vigesimal.tech/service/migration-modernisation): Legacy systems moved to modern, scalable architectures without stopping the business.
- [Cloud optimisation](https://vigesimal.tech/service/cloud-optimisation): As you scale, cloud waste compounds. We audit what you run, cut what you do not need, and right-size the rest.
- [DevOps & SRE consulting](https://vigesimal.tech/service/sre): We change how you release and operate: CI/CD your team trusts, observability worth paging on, and infrastructure that holds at 3am.
- [Custom software development](https://vigesimal.tech/service/dev): Tailor-made web and mobile applications built around how your business actually works.
