OLEARIS

Working with Olearis has been a very good experience for us over the years. They first helped us build our Android app from scratch, and later they also supported the further development of our iOS app. Since then, they have also helped with QA, maintenance, and new features as the product continued to grow. The app includes profile creation, a matching feed with filters to help users find new friends nearby, discussion groups, an activity calendar for meetups, and subscription features. We have only received positive feedback from users, which shows the quality of both the product and the team behind it. Olearis always delivers on time and stays within budget. They are also easy to work with every day: communicative, thoughtful, and truly involved in the project. What stands out most is their leadership, dedication, and the fact that they do not just complete tasks, but also share useful ideas and feedback during the process.

We’ve had a really strong experience working with Olearis. They supported us across research, product strategy, UX/UI design, and full frontend and backend development for our platform. The app is now live on both the App Store and Google Play, and the response from users has been very positive. They did a great job managing a large number of requests and changes while still keeping the project organized and moving forward. The team listens closely, understands the bigger picture, and gives thoughtful guidance when something is not the best fit because of budget, timing, or market reality. They bring a high level of experience to every part of the work.

The iOS app feels really smooth, and Olearis has been a big help on both the mobile and backend side. One of the biggest wins was refactoring a backend solution and reducing memory usage from 10 GB to just 30 MB, which made a huge difference in performance. They’ve also supported us with iOS and Android development, backend APIs, integrations, releases, QA, and beta testing. The team is easy to work with, stays on top of timelines, communicates clearly in Slack, and uses Jira and Notion to keep everything organized. We especially appreciate how flexible they are when priorities or budgets change, and how they always seem able to find the right expertise for whatever challenge comes up.

Alexander and the whole team at Olearis really went above and beyond on this project. It was a pleasure working with them. They quickly understood what needed to happen, helped us prioritize the work, produced some excellent designs, and developed and launched everything very fast. There was also a lot of creative, out-of-the-box thinking across different areas. They are highly pragmatic and were always willing to share their knowledge and advice. Everyone on the team was fantastic. Easily one of the best experiences I’ve had on UpWork, and we’ve already continued working with them on other projects. Highly recommended.
