  • As a Senior Android Developer at ONE ZERO, my main job, besides hands-on development, is to make sure features from the product team are ready to be built and make sense for the business. I focus on asking all the necessary questions upfront so we don't hit unexpected problems once we start coding.
  • I constantly look for ways to make our project better and more efficient. This includes:
  • Updating our tools and libraries.
  • Speeding up build times for the team.
  • Making sure we use the best and clearest architecture.
  • I also run the Mobile Guild, which is the meeting point for all mobile developers in the organization. I share practical content with the team on topics like:
  • Solid mobile architectures
  • AI tools that help us code faster
  • Smart development methods
  • I am always working to bring in new AI tools and development methods - and most importantly, to help the team change their thinking to fit the new era of AI development.
