In my current role at SYTOSS, Bratislava, Slovakia, I am actively contributing to the Foodmachine project. This entails developing an Android application for creating various types of coffee, complete with user systems, order creation, payment integration, and authorization features. I am proficient in Kotlin, Java, and Jetpack Compose, utilizing tools like Gradle, Android Studio, and Figma.
Previously, I was part of the Hydra project at SYTOSS, contributing to the modernization of sales activation for A1 Telekom Austria. This involved using SAP Hybris Commerce, Spring, Solr search, Junit, Mockito, Karate/Cucumber for testing, and tools such as Maven, Gradle, Ant, Putty, Win SCP, and Citrix.
Additionally, I played a pivotal role at Luxoft, where I contributed to projects like Advanced Trader for Swissquote, a Forex trading platform, and Commission Tool for Swissquote. My responsibilities included coding, code reviews, integrating software components, troubleshooting, debugging, and creating technical designs. I utilized technologies like Spring, Junit, Mockito, JBehave, REST, Hibernate, and more.
My experience also includes an internship at Luxoft, where I worked on the Quote Predictor project for Swissquote. This application focused on predicting the price, growth, and fall of cryptocurrencies using Spring Boot, JDBC Template, Junit, Mockito, Deeplearning4j, and Liquibase.
Beyond my technical skills, I am committed to continuous learning and staying updated with emerging technologies to further contribute to the success of my projects.

Applications and services I developed and improved were from many different subject areas: market exchanges, money transfer, time tracking, speech analysis, admin panel for accountants, fuel sale, etc. Some of them were built as monolithic systems, others have microservice architecture, some of them were deployed on local servers in their own data centers and others used clouds.
I am a perfectionist and have a strong idea that the most valuable thing we have is time. That is why I always try to use time as efficiently as possible, if I can change something for the better, I will do all I can to not miss this opportunity. If a question or issue could be resolved on my level, without any attention/time from colleagues/customers - it would be done so, if only we did not agree differently before. On the other hand, if I have a different point about some methodology or technology we want to implement with my colleagues - it will be better not to be self-confident and find the final detailed solution through team brainstorming.
I don't want to spend my own time on the test task because this activity could not get real feedback about a person and how his skills make the project better.
I don't like the companies where 1st requirement is 'to be offline at the office' because what people do is more important than where they are sitting right now, on my mind
