About us:
AppUnite is a Software Development house based in Poznan, Poland. We deliver software to range of companies all around the world since 2010. We always pick the newest software trends when implementing applications for our clients. We work remotely and onsite with clients from US, Europe and Asia.

Even though we started as a mobile applications software house, nowadays we have equally large groups of back-end and front-end developers as well. Our main tech stack includes Elixir/Node.js for the back-end, React/Vue for the front-end, Kubernetes for CI and Swift/Kotlin/Flutter for mobile apps.

We follow modern ways of async way of working: JIRA/ClickUp/Slack + Git + CI. We constantly convince our clients (mainly with success) that working with legacy solutions rarely is a good idea. Every week we do a company-wide session on our internal processes. We host Poznan Elixir Group meetups, and have people that have spoken on some of the biggest Elixir and JavaScript conferences in the world. For two years we’ve been running a Workation programme in remote locations like Thailand or Portugal to keep ourselves in high spirit and get that gorgeous tan.
