Backend Developer · Computer Engineer
I am a computer engineer. On the backend side I work with Java and Spring Boot. I also build projects with C#/.NET and ABP Framework, and keep broadening my experience across different technologies. I take part in the various stages of development, from database design through to putting the application into production.
About
I graduated in Computer Engineering from Trakya University. I work on backend development, mainly with Java and Spring Boot, and also run projects with C# / .NET and ABP Framework. Rather than simply finishing the task handed to me, I prefer to be involved in how the architecture is built — from the database schema to the API design.
So far I have worked on RESTful services, microservice architectures and third-party API integrations. I automate repetitive operational work with n8n. On the deployment side I use AWS and Docker; keeping a service running in production is as much my responsibility as writing it.
I usually learn a new technology by trying it out on a small prototype. Faced with a problem, I go for the solution that works and stays easy to maintain over time, not the flashiest one.
Experience
Kafein Technology
Back-end Developer Intern
- Built a Java client library that simplifies Keycloak management in Spring Boot projects.
- Designed a fluent interface covering 212 endpoints of the Keycloak Admin API.
- Split user, role, client, realm and authentication flow management into modular services.
- Added Spring Boot auto-configuration so the library integrates into projects as a single dependency.

- On a team I joined voluntarily while still studying, we built the backend of web and mobile applications with Java and Spring Boot.
- Developed RESTful APIs, took on database management and set up integrations with external systems.
- We ran deployment on AWS EC2 and stored media files on S3.
- Worked on the live messaging infrastructure and backend service integrations.
- We coordinated with other teams to keep the services maintainable in the long run.
