About

About

I work as a Full Stack Developer at Safran Cabin, building internal tools that improve engineering workflows with a focus on automation, performance, and usability. I work with JavaScript and TypeScript using React, Vue.js, and Node.js to build dynamic interfaces and scalable APIs, as well as C# and ASP.NET for backend services.

I apply Clean Architecture, SOLID, and Design Patterns in my daily work and actively contribute to system design, from service integration to backend structure, always aiming for maintainability and scalability. I enjoy building well-structured, high-performance software and continuously improving my knowledge of software architecture.
