Selected for Turkey's highly competitive 'Java Challenger' internship program where interns used Java with Spring Boot to develop the most advanced and complex backend system to compete for the grand prize. The program lasted one month, during which I implemented a microservice architecture fully deployable with Docker Compose, incorporating multiple aspects of distributed backend architecture- Managed databases using PostgreSQL and developed robust back-end solutions using Spring Boot and Hibernates- Implemented Elastic Search to support full-text search- Built an event-driven architecture utilizing Kafka Message Broker for reliable and scalable communication between services.- Designed a scalable micro-service architecture using Spring Cloud, fully deployable with Docker and Docker-Compose.- Implemented authentication services, including OpenLDAP, Google Auth, and various OAuth2 servers, to ensure secure access.- Deployed a scalable load balancing system using Eureka Naming Server, resulting in a 40% reduction in response time and improved system reliability during peak traffic periods.- Designed and implemented a centralized API management solution using Spring API Gateway, streamlining service integration and reducing development time by 30%.- Implemented notification system with multiple channel such as Email and In-App notification and kept record of notifications using MongoDB.- Enhanced system observability by implementing comprehensive logging architecture using Spring AOP, reducing debug time by 50% and enabling rapid incident resolution.

- Developed a scalable back-end project using Node.js and MongoDB for Boyner, one of Turkey's largest retail companies, serving over 10,000 users with robust notification systems and efficient cloud deployment on Azure.- Engineered a high-performance CRUD application processing 500K+ daily requests with 99.9% uptime.- Took a part of implementing end-to-end CI/CD pipeline using GitHub Actions, reducing deployment time by 60% and achieving automated testing coverage of 95% for Azure cloud deployment
