- Collaborate closely with the product team to transform feature requests into actionable implementations.
- Lead code reviews to ensure code quality, setting a high standard for engineering excellence.
- Mentor and support junior engineers, sharing expertise to elevate the team.
- Optimize our database systems through performance analysis and scalability planning.
