I have extensive experience with React, having worked on several projects where I developed dynamic user interfaces, managed state with Redux, and optimized performance using hooks and context API. I also have experience with Angular, where I implemented complex forms, utilized RxJS for reactive programming, and ensured code reusability with custom directives and services.

I typically start with understanding the data requirements and then design the schema accordingly, ensuring normalization and efficient querying. I have experience with both SQL databases like PostgreSQL and NoSQL databases like MongoDB. I use ORMs like Sequelize or Mongoose to interact with the database, ensuring data integrity and performance.

I follow best practices such as input validation, parameterized queries to prevent SQL injection, and using HTTPS to encrypt data in transit. I also implement authentication and authorization mechanisms, such as JWT or OAuth, and regularly update dependencies to patch security vulnerabilities. Additionally, I conduct regular security audits and code reviews to identify and mitigate potential risks.

I use a systematic approach, starting with identifying the issue through logs and error messages. I then isolate the problem by breaking down the application into smaller components and testing each one. I leverage browser developer tools for front-end issues and server-side debugging tools for back-end problems. I also use version control to revert changes if necessary and collaborate with team members to resolve complex issues.

I am proficient with Git, using it for branching, merging, and managing codebases. I follow a feature-branch workflow, ensuring that each feature or bug fix is developed in a separate branch and then merged into the main branch after review. I also use Git for collaborative development, resolving merge conflicts, and maintaining a clean commit history.
