Java Developer | Spring Framework | FinTech, EV Charging

Greetings! I am a Java Developer with 4 years of experience in Tech. My skills & abilities allow me to cover all aspects of Back-End development: design and develop a robust Back-End part, and then cover the product with Unit Tests. Due to my profound background in app development for industries like Electric Vehicle Charging, I prefer complex and meaningful projects. Invite me for an interview if you feel like I’m the right person to turn your ideas into reality. TECHNOLOGIES I USE ✅ PROGRAMMING LANGUAGES: Java, SQL ✅ FRAMEWORKS: Spring (Spring Data, Spring Boot, Spring Security), Hibernate ✅ DATABASES: MySQL, JDBC, Hibernate ✅ WEB: Servlets, JPS, Tomcat ✅ TESTING: JUnit ✅ Operating systems: Windows, Linux, Unix ✅ OTHER: Docker, Maven, Git, OCPP 1.6 In addition to the above, I possess a solid grasp of Algorithms and Data Structures. Also, I have extensive Functional Testing and Unit Testing skills. API Integration is also among my strongest sides. MY MOST RECENT PROJECTS ✅FinTech system: The main purpose of the system is to simplify the communication between banks and retail customers who want to get a loan for buying goods. The staff at the retail shops use the system to distribute the buyer’s data across multiple banks. That is done to see which bank will accept the buyer’s loan application at the most optimal conditions. I'm worked on the improvement of the existing codebase; integrated the APIs of multiple banks single-handedly; insured the high quality and full test coverage of the codebase ✅EVCS sharing platform for the Swedish company: A platform consists of 2 parts: the first one is for the owners of the Electric Vehicle Charging Stations, who have installed them and would like to open them for the public in order to gain additional profit; the second one is a mobile app for the drivers who would like to navigate to the available chargers nearby, manage the charging process, and pay for charging. On this project, I performed as a Back-End developer. I'm worked on the improvement of the existing codebase; integrated different payment systems & EV Charging station vendors; was responsible for new feature development LANGUAGES I SPEAK Ukrainian is my native language. Besides, I have strong English skills. Most of my previous customers were English-speaking, so I am comfortable communicating in English. MY TEAM I am at ease as an individual contributor, but being a team player works best for me.
