  • Comfortable with Android Studio, git, Firebase, and performance profiling tools
  • Experience with maintaining apps on Google Play (100,000+ downloads)
  • Familiarity with Agile workflows (Kanban)

Nice to Have:

  • Familiarity with CI/CD pipelines
  • Familiarity with iOS deployment (not required, but a bonus)

HOW DO WE WORK?

We are a distributed team of more than 150 people, all working remotely. We value open communication, proactivity, and work/life balance, and we measure our freelancers on performance, rather than on the time spent on the job.
