Why Me?
With my many years of experience and work on projects of varying sizes and requirements, I have gained extensive knowledge in various areas.
As a frontend developer, I prioritize building technically sustainable projects that meet the needs of modern web applications in the long term. I also engage beyond my role by providing valuable suggestions that optimize the entire development process.
I love combining design and technology to create user-friendly and responsive applications that are both functional and aesthetically pleasing. This includes simplifying the editing of images and designs.
Through regularly leading technical meetings and taking responsibility for the frontend in various projects, I have learned to effectively manage my time and that of my colleagues. I place great importance on open and transparent communication.
