For the mobile app we are developing for the fuel company Lukoil, the main structures I have directly contributed to include: - Setting up Google Firebase to send push notifications to users' phones. - Establishing the "Campaign - Coupon" structure that enables users to earn coupons based on their spending. - Developing payment logic to reflect the provisional charge to the bank, based on the fuel amount the user will pay. This includes notifying the bank about the total amount, partial amount, or cancellation of the payment.Technologies we are using for the application: Spring Boot, Java 17, Hibernate, Postgres, Kafka, Jenkins, Kubernetes.

A ”TLN eCOM” Java project was created which is built with microservice architecture, hosted on dedicated server.Developments were made in all end‐to‐end points of the related project. All database design and development of the project was done end‐to‐end on MongoDB and PostgreSQL. DevOps processes were managed. CI/CD pipeline created with Jenkins. In the related Java project, up‐to‐date software tools such as Netflix Eureka Server, Apache Kafka, Redis, Kubernetes and Keycloak were used.

We took full-time Java and React courses for two months. At the end of Bootcamp, I did a graduation project that I completed the backend with Java and the frontend with React.
