    I'm a Senior Software Engineer with over 9 years of experience, I have gained extensive expertise in designing and implementing high-quality software solutions that meet the client's business requirements. Throughout my career I was working on multiple projects, here I'm sharing three of the most challenging ones: At UBS (a Swiss bank with a $60bln capitalization), I was a Senior Java Developer, and I was responsible for developing a regulatory reporting engine to handle dozens of millions of transactions the bank processes daily. This project was part of implementing their new business requirements around designing a project on an entirely new event-driven technological stack. There were several main challenges that I faced when designing and implementing the system: 1. System should handle millions of transactions per day that have to be reported in a timely manner. 2. System should be tolerant to hardware failures, including the loss of the entire data center. 3. Around 40 developers should be able to work on the project productively with minimal conflicts. 4. Correctness of reporting is essential – every introduced bug can have disastrous consequences – the system should have checks in place that prevent buggy code from being deployed to production. 5. Transaction reporting domain is very complicated, and business requirements are frequently changing. System design should be flexible enough to adjust to the required changes. 6. There are multiple stakeholders involved; each has different requirements for the system. At Denario, a fintech startup, I worked as a Senior Java Developer, assuming full responsibility for designing, developing, deploying, and maintaining the application and DevOps tasks. The main challenges in the projects were: 1. Developing a high-performance system 2. Integrating with multiple Open Banking providers 3. Ensuring the platform was scalable, fault-tolerant, and highly available 4. Ensuring the platform was secure and user data was protected 5. Collaborating with the product team to design features that met users' needs 6. Maintaining the platform and fixing issues that arose in production 7. Assuming full responsibility for the end-to-end software development process At the Ministry of National Defense of Poland, I was a Team Leader and Technical Leader responsible for providing e-learning solutions for hundreds of thousands of users. My role involved leading a team of developers, analysts, and testers to develop and maintain a learning management system. I have experience working with a variety of technologies, including: Java, Spring Framework, Spring Boot, Hibernate, JUnit, Spock, Apache Flink, Kafka, PostgreSQL DB, Oracle SQL DB, Elasticsearch, Microsoft Azure, Kubernetes, AWS I am passionate about software development and strive to stay up-to-date with the latest trends and technologies. I am dedicated to delivering high-quality solutions and exceeding client expectations.
