Design patterns provide established solutions to common design problems which can improve the efficiency and readability of your code. They help in creating reusable components and can significantly impact the maintainability of your applications.

SQL databases are relational and utilize structured query language for defining and manipulating data. Conversely, NoSQL databases are non-relational, allowing for more flexible data models, useful for handling unstructured data or when high scalability is required.

Debugging in Node.js can be approached by utilizing tools such as the built-in debugger, console logging, or using external libraries like 'debug'. It’s important to isolate problems in your code, systematically testing functions to identify where things go wrong.

Express.js is a minimalist web framework for Node.js that enables developers to create robust web applications and APIs efficiently. I have used Express.js to build server-side applications and RESTful services, leveraging middleware for functionalities such as logging and authentication.

To ensure code maintainability, I adhere to principles like SOLID and KISS. Writing clear documentation, using meaningful variable names, and implementing modular patterns all contribute to making my codebase easy to navigate and understand.

One challenging project involved revamping a legacy application using Node.js. We had tight deadlines while needing to ensure performance and scalability, which required close collaboration with the team to innovate the architecture and design patterns to enhance efficiency.

Collaboration with front-end developers can be streamlined by maintaining open communication. I focus on understanding their needs for API endpoints and data structure, using tools like RESTful APIs and JSON to effectively bridge our work without bottlenecks.

I'm keeping an eye on the advancements in ES.next versions, as well as frameworks like NestJS and their implications on server-side development. Additionally, I'm interested in TypeScript's evolving capabilities, which enhance JavaScript's robustness.

I have substantial experience working in Agile environments, particularly Scrum. I appreciate the iterative nature of Agile, allowing for frequent reassessments and adaptations, which aligns well with my commitment to delivering quality solutions on tight timelines.

For effective problem-solving, I focus on breaking down complex issues into manageable parts, engaging in team discussions for diverse perspectives, and utilizing proven methodologies like root cause analysis to pinpoint the source of issues before devising solutions.
