- Optimize database queries and eliminate performance bottlenecks
- Implement caching strategies to improve performance and scalability
- Debug and resolve production issues related to APIs, jobs, and system performance
- Monitor and improve application performance under high load conditions
- Collaborate with cross-functional teams to design and deliver high-quality solutions
- Write clean, maintainable, and well-documented code following best practices
- Mentor junior developers and guide them on system design and debugging
