Platform & Tools Engineering
We design and build the backend services, internal tools and build pipelines that products run on. We write code in C++, C#, Go, Rust and Java, work across the main cloud providers, and hand everything over to your engineers with full documentation when the project ends.
What this covers
Built with your engineers
Our engineers can join your existing team or take on a service from design through to launch. We work with the languages, cloud providers and tools your team already uses.
Backend services
Accounts, entitlements, subscriptions, notifications and the other services a live product needs, designed for the traffic you expect at launch.
Build and release pipelines
CI/CD, automated testing and release tooling that help your team ship updates safely and often.
Load testing
Test platforms that simulate real traffic before launch. One of ours simulates 10 million concurrent users and kept all of a client's existing tests from the previous 20 years.

Frequently asked questions
Platform and tools engineering is the work on the systems a product runs on behind the scenes. That includes backend services such as accounts and subscriptions, the internal tools a team uses every day, and the build pipelines that get updates from a developer's machine to players or customers. Terminal Velocity designs, builds and supports all three.
We build the services a live product depends on, including accounts, entitlements, subscriptions and notifications. Each one is designed around the traffic you expect at launch, so it holds up when people arrive. We can build a single service for your existing platform or a full backend for a new product.
Yes. We build load testing platforms that simulate real traffic so you can find the limits of your systems before your users do. One platform we built simulates 10 million concurrent users, and it kept every test the client had written over the previous 20 years.
Yes. We set up CI/CD, automated testing and release tooling so your team can ship updates often and with less risk. That can mean building a pipeline from scratch or improving the one you have, for example by cutting build times or adding automated checks before a release goes out.
Yes. Our engineers work in the languages, cloud providers and tools your team already uses, including C++, C#, Go, Rust and Java. They can join your team and work inside your processes, or take ownership of a service from design through to launch.
We hand the work over to your engineers with full documentation, so your team can run and extend it without us. If you want ongoing support after handover, we can agree that as part of the engagement.
