I have been working as a data scientist for two years in a SCRUM Agile environment. My responsibilities included predicting customer churn using LightGBM, feature extraction for a new project with Scala and Hadoop, extracting data from the Isbank app and analyzing user application history, and developing and running ML models in production. I achieved a 0.88 AUC score in the customer churn project, extracted data for 2 million daily users, built a Python model with an AUC of 0.95, and increased credit card sales by 8 times during the A/B test period.

As a Software Developer, I have won second place in a customer satisfaction development competition among young talents. My responsibilities include developing customer satisfaction solutions, participating in competitions, analysing customer feedback, and collaborating with other developers. My achievements include winning the customer satisfaction competition, developing innovative solutions, improving customer experience, and increasing customer loyalty.

For the past six months, I have been working as an Analyst Developer, developing Java applications, creating Spring Boot frameworks, designing SQL databases, and implementing Hibernate structures. I have achieved success in creating the infrastructure for the company's site, optimising telecommunication processes, increasing efficiency of the company's operations, and improving customer experience.
