Sergei Koiushev Email and Phone Number

I moved to Innsbruck and joined to the Samwin company as a software engineer. My team and I designed and developed PoC for Rocket.Chat and Samwin integration. After successful PoC I improved the solution to the production level. Also the documentation has been written and provided for customers. By now the solution uses by customers and parters. C# uses on backend side; MS SQL as a data base for persistent purpose and Type Script/Angular on frontend. After the release I worked and approved with the team a new roadmap planning approach and feature roadmap.

I became a mentor of a few junior engineers in 2017. I’ve been involved into design and manage an internal project. My role was a team lead, tech lead & project manager. Golang was used on backend side; MongoDB as a data base for persistent purpose and Type Script/Angular/Material design on frontend. We followed SRUM best practices in the team. The project was successfully released in 2018. The project is being used by service engineers. All juniors became experienced senior engineers and continue working in the company.After the successful release I became a team leader for a group of 7 experienced engineers and worked 2 years. My team and I have been developing object storage feature and other parts of the storage system. The storage system is developing for a server based on Open Power architecture. The project is written major in Golang. As well, I was in charge of design develop and release GUI & CLI for the Tatlin.Archive. We’ve released 3 new versions of the product.As experienced engineer and team lead joined and formed a new SCRUM team in the data path devision. My team and I have been developing cache functionality for block storage. This part has been developing in kernel space Linux. My responsibility was design and develop the new feature. Also, I communicated with other teams to integrate it into the system. The cache is important part of the system and the most customer facing. The crucial challenge was design and develop active-active cluster storage system. It should handle more than 1M IOPs. Also, it has to manage with failover scenarios. The system is named Tatlin.Unified and available for customer since 2020.

I’ve worked for KNS GROUP in 2016. I worked as a senior software engineer about 1.5 years. My team and I involved into developing block, file and object storage system. My responsibilities were design develop and test the object storage functionality.I became a mentor of a few junior engineers in 2017. We’ve been involved in design and manage an internal project.

I had been working for EMC corporation since 2013. I joined as a college intern and was promoted to software engineer in 2014. My team and I worked on a project known as ECS (Elastic Cloud Storage). ECS is a software-defined object storage platform. ECS supports various object-based and file-based protocols (e.g. S3, HDFS, Atmos, Swift, CAS, NFS). ECS provides geo-replication and global data protection optimization storage efficiency. The project is written primarily in Java. The technology stack is based on Spring framework, Guava, Apache ZooKeeper and Docker for product delivery. I became a inventor in 7 patents. https://patents.google.com/?inventor=Sergey+Koyushev&oq=Sergey+KoyushevTechnologies: Java 1.7/1.8, Spring framework, Python, robot framework, Docker containers.
