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.

Netherlands · 9 years of experience · Advanced/Fluent ·Published yesterday
Throughout my journey, I've had diverse experience, which included working on:
- Product for data transformations into a certain structure written in Oracle PL/SQL + Java;
- Big Data IoT platform for processing data from connected vehicles, where tech stack included Scala, Akka, Kafka;
- Java monolithic monsters with complicated business logic with attempts to modernise and loosen coupling;
- ETL pipelines built in Python + PySpark + Kedro;
- Couple of greenfield projects which consisted of microservices built in Java or Kotlin + Spring Boot, which communicated via REST and Kafka (that's also what I'm busy with at my current assignment).
I have found out that I have a deep passion for Java & JVM. I really enjoy looking under the hood, into the lower level concepts, reading the bytecode, analysing the behaviour of JVMs. It's not part of my day-to-day job, but I love engaging with the Java community, sharing knowledge at the conferences or through blogs.
The main reason for looking for a change is the intention to move to Sweden and live closer to nature. I would love any remote possibilities, and I'm happy to travel when needed.
