Reliable and scalable high-load platform
![]()
we did
We participated in the design of the architecture of the CAP system. Our goal was the seamless introduction of new features while retaining the stability and reliability of the project. The initial part of the platform that we started developing was tightly coupled to other parts of the system so we extracted it into a dedicated Scala service with its own CI/CD pipeline. We created a denormalized model optimized just for queries that was derived from original data. We also addressed the need for durable data exports and reporting. Our paramount goal was to migrate CAP to use the newest available versions of language, libraries, and frameworks.
Outcome
Throughout 2019 the client acknowledged how impressed they were with our commitment, execution, and expertise, so in 2020 they decided to form a self-organized team made up exclusively of our engineers. The team was operating in the agile methodology with the client’s Product Owner and Scrum Master. The team acquired responsibility for some modules that were part of the platform. It also helped outside of their scope on demand. Read more about the project in this case study.
Client needed
One major Cota Abstraction Platform pain point was performance decline as data volume increased. The high amount of information and its presentation in the user interface may lead to bottlenecks and performance issues resulting in a poor user experience. Also, it was crucial to allow end users to export, analyze, and conveniently create reports. Another platform's challenge was proper system monitoring implementation.
Client had
COTA Healthcare is a company founded by doctors, engineers, and data scientists. They combine oncology expertise with advanced technology analytics to organize and analyze cancer data to help with advanced patient care and research.

End-to-End transportation mode recognition software
![]()
we did
The result of the first round of the workshops was the transport mode detection research document in which we described the steps needed to construct a flexible machine learning solution. This led to the development of platform architecture and a mobile application research mode. Then, we were collecting a lot of data base on the specified rules and processing it. After six months of development, we were ready for user acceptance tests of the system PoC. The cloud platform was ready and capable of serving requests from the mobile application. The machine learning transport mode recognition service was in place and waiting to run inference against acquired sensor data.
