Code Quality Hackathon 2022June 2022
Hackathons as an Innovation tool.
When it comes to innovation, people usually think of developing a digital product or integrating a new service, but it’s never just about these. Everything that improves a process or makes the experience offered more enjoyable is actually within the scope of innovation activities. There are some methods and tools used for this purpose, the place and method of application may vary, but the goal is clear, to be able to diversify the contribution offered.
The most fun of innovation tool is hackathons. In a situation where time, space, and other important resources are limited by various constraints, developers perform at their best for a goal and can go beyond their performance at other times. In fact, some of them can work miracles. As the terminal team, we organize hackathons every year and we enjoy the contribution these activities make to our processes.
So what is the Code Quality Hackathon?
However, this year there was a difference. We held an internal hackathon for the first time. Taking the expertise of our DevOps team with us, we designed the “Code Quality Hackathon” event for Turkish Airlines Technology employees and held it at our Libadiye campus on May 13-14-15, 2022.
With every activity in this event, it served the following purposes.
- To Improve code quality in our existing applications and to increase unit testing awareness.
- To increase communication between individuals and teams who have been away from each other during the pandemic period and to strengthen relationship between them.
- To contribute to employee engagement through new office and hackathon activities
What was included in the Hackathon?
CQH basically consists of 2 parts.
- Code Contest: Developers competed in 2 categories. Code Quality Issues and Unit Testing. You can review the scope and details of these categories in the section on the hackathon page.
- Social Activities: There was not only coding, but also various social activities. Refreshments for 2 days, playstation, table tennis, paper airplane, table football tournaments, award-winning trivia and an Ask Me Anything event with our general manager Kerem Kızıltunc.
What happened on the first day?
On Friday, May 13, 2022, at 08:00, the participants arrived at Turkish Airlines Technology Libadiye campus.

What happened on the second day?
The second day was the day when the teams gave their full concentration to the code repos and solved problems almost non-stop. In fact, the focus was so high that the organization team decided to cancel the “speed networking” event in order not to spoil this energy. At the end of the day, the Trivia event was held using Kahoot and Hilal Aşağıçayır came first with her high performance and won a surprise award.
