I have extensive experience with front-end technologies. I have worked on several projects where I utilized HTML for structuring web pages, CSS for styling, and JavaScript for adding interactivity. I am proficient in using frameworks like React and Angular to build dynamic and responsive user interfaces. My experience includes optimizing performance and ensuring cross-browser compatibility.

I have experience with both SQL and NoSQL databases. I design schemas that are optimized for performance and scalability. I use indexing, query optimization, and caching strategies to ensure efficient data retrieval. Additionally, I regularly monitor database performance and make necessary adjustments to maintain optimal efficiency.

I am proficient in using Git for version control. I have experience with branching, merging, and resolving conflicts. I use Git workflows like Git Flow to manage feature development and releases. I also use platforms like GitHub and GitLab for collaborative development and code review processes.

I follow best practices for web application security, including input validation, parameterized queries, and secure authentication mechanisms. I am familiar with common vulnerabilities like SQL injection and XSS and use tools like OWASP ZAP for security testing. I also ensure that sensitive data is encrypted both in transit and at rest.

One challenging project involved developing a real-time analytics dashboard. The main challenge was handling large volumes of data and ensuring real-time updates without performance degradation. I overcame this by implementing a microservices architecture and using technologies like Kafka for data streaming. I also optimized the database queries and used caching to improve response times.
