I migrated graphics data to a CDN and updated the Laravel platform, contributing to increased application relevance. I deployed the server part on Laravel using the VAPOR orchestrator. I built robust CI/CD pipelines using Docker and GitLab CI to deploy application intoAWS cloud. I made architectural improvements that increased project reliability and scalability, such as integrating the storage system with S3, implementing CDN for publishing, updating the security policy, and transitioning from Elasticsearch to OpenSearch.All proposed modifications to the architecture and technology stack were approved by management and successfully implemented. The environment was launched and ready for application testing, which allowed the company to modernize the stack, reduce infrastructure costs on 15% , and speed up the deployment process.Key Skills:• AWS cloud, AWS Lambda• Docker, Kubernetes, VAPOR, GitLab• Lavarel• Linux Show less

I worked at top Russian bank. I was involved in deploying development environments, selecting technologies, and designing architecture. I designed and implemented architecture for several projects, all of which were successfully launched, earning me special recognition from management. I transformed the legacy delivery system into a robust, scalable solution using DevOps methodology. By implementing a CI/CD process, I reduced the application build time from several days to 30 minutes… Show more I worked at top Russian bank. I was involved in deploying development environments, selecting technologies, and designing architecture. I designed and implemented architecture for several projects, all of which were successfully launched, earning me special recognition from management. I transformed the legacy delivery system into a robust, scalable solution using DevOps methodology. By implementing a CI/CD process, I reduced the application build time from several days to 30 minutes, leading to a 20% reduction in infrastructure maintenance costs while maintaining all mandatory testing stages. I developed an alternative process for rolling forward database structure changes using Liquibase, significantly enhancing team productivity. I built layered perimeter defense against applied threats based on OWASP standards, ensuring the bank met the highest cybersecurity standards. Additionally, I implemented PCI DSS requirements as part of the application architecture. I set up monitoring, metrics, and logging, improving service reliability to 99.99%. I also documented all product support processes and trained support and operation teams.Key Skills:• Docker, Kubernetes, integration with GitLab / Bitbucket• Jenkins, Gradle, Ansible, Nexus• Linux, Bash• Logging and monitoring systems based on ELK, Zabbix, and GrayLog• Cloud services administration, including SberCloud• Software development and system administration• Java/ SpringBoot, Oracle/ Postgresql / GreenPlum, JS/React• IBM Java, IBM WAS, IBM MQ Show less

I developed and maintained several Java micro-services using Java 8/11 and Spring, managing the full development cycle, including integration with various external and internal systems and proprietary data buses. I resolved emergency situations and performance issues in various information system components and implemented continuous delivery and monitoring systems to improve infrastructure efficiency and reliability.I automated application deployment and performance monitoring.

I resolved emergency situations and performance issues in various information system components and implemented continuous delivery and monitoring systems to improve infrastructure efficiency and reliability.I automated application deployment and performance monitoring. By optimizing infrastructure, using queues to distribute load, and automating error handling, I improved system performance, reduced the burden on technical support, and increased system reliability.I increased security levels by introducing two-way encryption and new data exchange protocols, significantly improving information security. Additionally, I coordinated the work of experienced developers to ensure projects were completed on time and with high quality.Key skills:• Java 8/11, Spring, Camel• Oracle DB / Mongo DB• ActiveMQ, Oracle AQ, ELK/Zabbix, Java Melody• Tomcat / Weblogic / Jetty• Git, Artifactory• Linux, Bash Show less
