I'm Andrew Nikitin,
a Senior Java DevOps Engineer
Summary
20+ years of Software Development experience in various programming languages.
12+ years of experience developing systems/software for large business environments using Java, troubleshooting skills, engineering, programming, testing, and debugging.
6+ years of experience with Agile development environment Scrum, Kanban, and Waterfall methodologies, and willing to embrace Agile principles in daily job.
3+ years of experience in DevOps engineering
3+ years of experience developing applications using microservices, Java Spring Boot, containers, container technologies, and container management systems.
Developing maintainable and robust micro-services-based server software solutions applying Java and technologies like Spring-Boot, Kafka, cloud solutions, SQL, and NoSQL databases.
Proficient experience in Java development of Enterprise applications, unit and integration autotests (REST API, GRPC, Back-end, JEE, and console APP).
2+ years of experience with AWS tools: AWS SDK, developing Lambda functions, S3 SDK, EC2, AWS API gateway, AWS SQS, and SNS, Repositories, Monitoring, and Logging.
2+ years of experience in Angular 12+ (Typescript, Javascript), Bootstrap, HTML, and CSS.
Strong experience with Software Engineering/CS fundamentals, including data structures and algorithms.
Applying OOP, SOA, SOLID principles, and Design patterns with the ability to implement them in Java.
Strong experience in DevOps tools: Docker, Docker-Compose, Linux, VM, Docker, Kubernetes, Helm, OpenShift, Gitlab CI, Terraform, Jenkins.
Confident with databases such as PostgreSQL, Oracle DB, H2, MySQL, Aurora, and MongoDB, optimizing SQL queries and DB Structures.
I can install from scratch, manage cloud services, Docker containers, OS, Virtual machine, and required server software, install from scratch, and then manage Kubernetes.
I love building and designing things from scratch. In addition, I am passionate about customer success. Focus is on results, not activity. Learning EVERY DAY is a key to progress.
I see ambiguity and rapid change as an opportunity – not a threat. I believe the Full stack engineering is about being excited to work on the whole product, being eager to learn new technologies, and being ready to go where you’re needed most.
