In my previous role, I led a project to integrate our CRM system with a new ERP system. This involved mapping data structures, designing APIs, and ensuring seamless data flow between the two platforms. I used SQL for data mapping and RESTful APIs for communication. The project was successful, reducing data entry errors by 30% and improving overall system efficiency.

I follow a systematic approach to troubleshooting. First, I isolate the problem by gathering relevant logs and user reports. Then, I use debugging tools to trace the issue to its root cause. Once identified, I implement a solution and test it thoroughly to ensure it resolves the issue without introducing new bugs. Finally, I document the solution for future reference.

I have extensive experience with SQL and NoSQL databases. I've optimized database queries by indexing, partitioning, and normalizing data structures. I've also implemented caching mechanisms to reduce query load times. My efforts have resulted in a 40% reduction in query execution time and improved overall system performance.

I prioritize security by following best practices such as input validation, using secure coding standards, and regularly updating dependencies. I also conduct regular security audits and penetration testing. Additionally, I educate my team on security protocols to ensure a collective effort in maintaining application security.

I am proficient with Git for version control and have used platforms like GitHub and GitLab for collaborative projects. I ensure clear commit messages and maintain a clean commit history. For collaboration, I use tools like Jira for task management and Slack for team communication. These tools help in tracking progress and ensuring seamless collaboration.
