  • Provide technical guidance to developers, promoting their growth and development.

  • Conduct code reviews and provide constructive feedback to improve the overall quality of the codebase.
  • Identify and address performance bottlenecks and optimize application performance.
  • Stay up to date with industry trends, emerging technologies, and best practices to continuously improve our development processes.
