As a software architect, I oversee the architectural roadmap for the 3 different projects, developing and implementing required features. Also, I am acting as technical manager, providing technical assistance and introducing new development processes. Technologies: Java 8, Java 11, Java 17, Spring, Spring Boot, Spring Security, Spring Cloud, Spring Batch, Spring Data, Maven, RabbitMQ, CI/CD, GitLab CI, Maven, PostgreSQL, SQL, MS SQL, OracleDB, Microservices, Docker, Kubernetes✅The whole project ecosystem was prepared and ported to the OpenShift Environment to ease the management and CI/CD processes. The deployment time was reduced from 8 to 1 hour. ✅The data loading subsystem was completely reworked using open-source Java technologies, to be horizontally scalable and process any amount of data, that was necessary for our most important customers. As a result - more than 10000000 records might be uploaded without overloading any system component✅The documentation and API were reworked to accelerate external integrations. The time spent by our customers on creating extensions was reduced to 80%. ✅More than 10 new source code standards and approaches were introduced: unit testing, code style, static code analysis, etc.

Sberkredo was a crowdfunding platform, run by one of the biggest banks in Russia. I was not only in charge of preparing the development strategy for a new platform, but I also acted like an architect, preparing technical solutions, development processes, etc. ✅A new platform was deployed within less than 1 year by a team of 6 developers✅A brand new transaction processing system was implemented to make the system independent from enterprise vendors, as SAP, which saved about 8 months✅Camunda BPMN engine was introduced to organize business process definitions and automation in a declarative way. Any business process might be published by 1 system analyst within 3-4 days✅More than 10 modules were created to complement Camunda BPMN to support its integration into the corporate ecosystem

As a senior software engineer, I participated in the Digital transformation process, to bring modern technologies and approaches to the company.

Magnit is one of Russia's largest food retailers. In 2010, Deloitte – a multinationalconsulting services provider – included Magnit in its list of the world’s top 250 retailers. In 2014, Magnit became the largest Russian importer. In Magnit I was in a team responsible for Enterprise Service Bus (ESB) - a system, that manages data exchange between all the components and systems inside the company. ✅ESB was ported from a proprietary technology to Open Source Apache Camel. It simplified the development process a lot and reduced costs to 0✅A new JPA-like framework was created to define the data exchange protocol between Java applications and Oracle DB.
