Front-end development focuses on the user interface and user experience, involving technologies like HTML, CSS, and JavaScript to create interactive and visually appealing websites. Back-end development, on the other hand, deals with server-side logic, databases, and application architecture, using languages like Python, Java, or Node.js. As a Full Stack Developer, I bridge both areas, ensuring seamless integration between the front-end and back-end to deliver a cohesive and functional application.

I implement security best practices such as using HTTPS, validating and sanitizing user inputs to prevent SQL injection and XSS attacks, and employing authentication mechanisms like OAuth or JWT. Regularly updating dependencies and libraries to patch vulnerabilities is also crucial. Additionally, I conduct security audits and penetration testing to identify and mitigate potential risks, ensuring the application adheres to industry standards like OWASP guidelines.

I have extensive experience using Git for version control, including creating and managing repositories, branching, merging, and resolving conflicts. I follow best practices like writing clear commit messages, using feature branches, and conducting code reviews via pull requests. Git allows me to collaborate efficiently with teams, track changes, and maintain a clean and organized codebase, which is essential for scalable and maintainable software development.

I start by reproducing the issue and isolating the problem to either the front-end or back-end. For front-end issues, I use browser developer tools to inspect elements and debug JavaScript. For back-end issues, I rely on logging and debugging tools specific to the framework or language. I also use systematic testing, such as unit and integration tests, to identify root causes. Collaboration with team members and thorough documentation help streamline the debugging process and prevent future occurrences.

I have designed and consumed RESTful APIs extensively, ensuring they follow best practices like using proper HTTP methods, status codes, and versioning. I integrate APIs into applications by making HTTP requests using libraries like Axios or Fetch in the front-end and handling responses to update the UI dynamically. On the back-end, I create APIs using frameworks like Express.js or Django, ensuring they are scalable, secure, and well-documented for seamless integration with other services.
