I want you to help me write a cover letter for job applications that highlights my technical skills. I have two years of experience with web technology, including eight months as a frontend developer. I have worked with several tools and technologies such as [...Tech Stack], and I am now looking to develop my full-stack development skills and take on more challenging roles. I also aspire to lead a T-shaped career. Can you write a professional and effective cover letter that presents me as a strong candidate for job applications?
