Supported architecture of 5 microservices, that were connected to each other by Kafka, HTTP and GRPC. 3 of them were implemented using Java, 2 of them were implemented using Ruby On Rails and TypeScript. One of my proposed solutions was resource usage optimization of AWS EC2 machines, that performed Github build of Docker images
List of some responsibilities:
1. Close communication with technical staff from customer side about supported 5 microser-
vices and other.
2. Consultation teams about ways to resolve infrastructure problems. 3. Providing POCs for new architecture challenges.
4. Providing support for teams during solution implementation.
Technologies: AWS (CodeBuild, CodePipeline, Connector, EC2, S3, Security Groups, IAM, Auto Scaling groups, LoadBalancer, CloudWatch, CloudFront), GCP, Ruby On Rails, Vertx, Java 11/17, Github CICD, Jenkins, Artifactory JFrog, Kafka, MySql, TypeScript, React.
• Introduced two POC. One is Kafka tracing implementation for reactive framework Vertx, that was successfully implemented and delivered to production. Second one is adding ability to use locally changed JavaScritpt code on the fly for production without reboot application, that leaded to reducing of AWS EC2 costs.
• During building new microservice, our main goal was to have it running in AWS. We used for that AWS CodeBuild, AWS CodePipeline connected to Github by AWS Connector, EC2, S3, Security Groups, IAM. Second part was to add AWS Auto Scaling groups and application load balancer. For metrics we used AWS CloudWatch. Another goal was to get media files from different time zones. We archived it by using AWS CloudFront before S3 bucket. As we loaded data from different zones, it became available to use cache from CloudFront
• Implementing SaaS for B2B customer. Technical owner of several parts of the solution, using ElasticSearch, Cassandra, RabbitMQ, Redis were examined
• Implementation Spring reactive RabbitMQ client for core solution.
• Implementation reactive Profiler for platform solution.
Provided POC how to migrate from legacy Java microservice on Spring to Quarkus + Native image and realized it in production solution. Consult on pre-sale calls with AWS infrastructure (migration and hybrid environment). Supported two projects with the building of architecture solutions.
