Backend development of an analytical platform that helps with anti-fraud

Participated in the development of various projects. I mainly worked on the backend but also had to solve problems on the frontend. Some projects I have worked on:https://cleverbase.com/In this project, the backend was a set of microservices written in Scala. I worked on one of these services. The service was a smart proxy wrapper over HSM. It provided the ability to perform some operations, such as creating users, keys, and signatures. While working on it, I worked quite closely with cryptography, for example, I implemented some noise protocol patterns. Main stack: cats and cats-effect, also some fs2. Synchronous requests were made via gRPC, and events were also listened to and published via SNS/SQS on Amazon. Postgresql was used to store data. The service was successfully launched.We tried to stick to DDD for writing business logic. For tests, we used the cucumber and BDD approach.We worked according to the agile methodology.https://www.cirlinq.nl/In this project, I implemented the processing of IFC format files, as well as the visualization of 3D models. To process files, a service was implemented in Python; all CRUD operations were processed by the NodeJS server. The client application was implemented in Angular. MongoDB was used to store dataThe company’s internal service for storing logs in the Ethereum blockchain was also implemented. Used NodeJS for the backend and Solidity to write a smart contract that stores the logs.
