• Managing and coordinating the efforts of 10 backend developers across 3 cross-functional teams, ensuring efficient allocation of resources and timely completion of projects.𝐓𝐞𝐜𝐡 𝐬𝐭𝐚𝐜𝐤: Kotlin, Java, Spring (Boot.
• Improved the processing system's performance (the core of the system) by reimplementing logic without Kafka transactions (implemented Transactional Outbox pattern), resulting in a x3 increase in processing speed.
• Eliminated monolithic build in CI/CD and versioning of development artifacts, resulting in increased independence of microservices and a decrease in cascading defects.
• Developed a process for managing library updates, resulting in a 90% decrease in the time required to update libraries and minimizing the risk of using outdated or vulnerable code.
• Formulated and deployed an effective workflow to manage production defects, resulting in maintaining an average of fewer than 10 open defects at any given time, this has increased quality of user experience.
• Implemented the Trunk Based Development methodology in one of the teams, enabling the release of features on an individual basis without the need for a release train. This transformation decreased time to market.

• Led a team in the development of 3 projects: - a B2B platform for business travel management; - a conveyor for issuing bank guarantees; - a digital banking system based on existing solutions.𝐓𝐞𝐜𝐡 𝐬𝐭𝐚𝐜𝐤: Kotlin, Spring.
• Took an active role in establishing a brand-new development department, initiating operations from the ground up and successfully growing it to a robust team of 70 skilled engineers.
• Collaborated with my team to conduct a comprehensive analysis, leveraging CNCF guidelines, to carefully select and implement diverse infrastructure solutions, including monitoring systems, container orchestration.
• Architected the "dream pipeline" as a benchmark for teams to aspire to, breaking it down into templates, thereby enabling the implementation of a CI/CD as a Service approach.
• Successfully adopted an enormous codebase and documentation generated by a multitude of engineers from various company departments. Analyzed and deployed a portion of this codebase, creating a replica of the company's.

• Backend development of banking system based on the reactive stack and microservice architecture.
• Led a team of 8 backend developers in the development and maintenance of a banking system
• Implemented new architecture and business features, while migrating old ones from a legacy monolith based on PHP
• Assessed technical debt and organized refactoring efforts to improve the system's performance and scalabilityTech stack: Kotlin, Spring Boot, Spring WebFlux, Spring Data R2DBC, Kafka, Kubernetes (OpenShift), JUnit.
• Successfully migrated part of the system's microservices to a hexagonal architecture and applied this architecture to new services in the future
• Regulated the technology stack used on the project, improving consistency and maintainability

As a Senior Software Engineer at an Investment Bank, I was responsible for the development of a high-load in-memory storage system. The system consumed data from various legacy systems and transformed, associated, and combined them into aggregate models. I utilized technologies such as Tarantool, Lua, GraphQL, Apache Avro, Docker, ELK, and Grafana to.
