Latvia · 6 years of experience · Upper-Intermediate ·Published yesterday
My forte lies in crafting software solutions tailored for the healthcare and fintech industries. Leveraging my deep understanding of Java and Spring Boot, I have been instrumental in building applications that are not only scalable but also efficient in handling voluminous data. My experience with Angular has enabled me to create intuitive user interfaces that enhance user experience.
My skill set extends beyond programming languages. I have hands-on experience with AWS, Docker, and Kubernetes, which I have utilized to deploy applications in a cloud environment and manage containerized applications. My database management skills encompass SQL (PostgreSQL/MySQL), MongoDB, and Neo4j, which I have used to effectively store and manage data across various applications.
I am adept at working with ELK and Kafka, having used them to build real-time data processing pipelines. My proficiency in Python and Go has been put to good use in the development of Web and Android applications.
