Our stack

Technologies

We pick the well-understood option unless there is a reason not to. Everything below is something we ship with regularly, and something your next engineer can pick up without a course.

Languages

The ones we write every week, not the ones we once tried.

TypeScript
JavaScript
Java
Python
Ruby
SQL

Web

Server-rendered React where it earns its keep, static where it does not.

React
Next.js
Vue.js
HTML
CSS
GraphQL

Mobile

One codebase on both stores, built to feel native rather than wrapped.

React Native
TypeScript
GraphQL

Backend

Boring, well understood services that hold up under load.

Spring Boot
Node.js
NestJS
Express
Rails
GraphQL

Data

Where the business actually lives, so it gets modelled properly.

PostgreSQL
MySQL
MongoDB
Redis
BigQuery
Airflow
DBT

Cloud and infrastructure

Defined in code, reviewed before it ships, reversible by default.

AWS
GCP
Docker
Kubernetes
Kafka
RabbitMQ
Jenkins

Monitoring

So you find out before your customers do.

Sentry
Datadog
Splunk
Graphite
Git

Using something that is not on this list?

We work in existing codebases regularly, including ones written in stacks we would not choose today. A short paid review comes first, so you get an honest read on the state of the code before either of us commits to a build.

Technology choices

The stack matters less than who maintains it

Tell us what you are running and what hurts. We will tell you whether the tooling is the problem or a symptom.
