As a Senior Software Development Specialist at LTA Teknoloji AŞ, I managed the processes of adding new features and fixing existing issues for a web-based online education system using PHP Laravel Framework, Vue.js, Inertia.js, and Node.js.

To ensure projects were completed on time and with high quality, I worked in close collaboration with the team and improved system performance by resolving technical issues. In the DevOps domain, I managed the deployment processes of software projects on Linux-based servers (CentOS, Rocky Linux). I made projects more manageable and scalable using Docker technology. Additionally, I configured IIS deployment structures for Windows servers, enabling more efficient deployment of .NET Core Web APIs. I also handled Nginx configurations on the server side. Throughout my two years of experience, I made significant contributions to the company’s digital transformation by delivering innovative solutions that met user needs.
