Trendyol Group•  April 2018 - June 2020

Trendyol is Turkey's first Unicorn Company. I worked in the Marketplace team.

Full-Stack Engineer

I built this startup from scratch. The application is constructed as a monolith Java Spring Framework app. At first, built in a single server instance then migrated to AWS with scalable and recoverable components. Also, I applied a web service to process images via ImageMagick lib. The service was constructed as a Spring Boot app and constructed inside AWS EBS. I was responsible for front end development (AngularJS), back-end development (Java, Spring, Git, Maven), dev-ops tasks (Bash, CentOS, Apache Httpd, Apache Tomcat, Network, DNS, Security, Backup Management). We worked in a weekly Scrum manner.

Senior Software Engineer

Nokia Networks•  July 2014 - March 2016

I worked with a team constructed in Turkey, the USA, and India. We maintained two different tools written one in Java and the other one in C#. The tools were accomplishing the same task that is to audit the parameters if configured correctly on network elements like MGW, BGW, etc.. I also developed and maintained the network element simulator which simulates any NE via the logs that our systems were generating. This tool was vital for the sake of detecting and fixing errors because most of the time, we were unable to connect and test the real NEs. Also, I presented the NE simulator in the conference ICCIT at Ankara Gazi University.
