  2. Proficiency in building scalable, reliable, and maintainable software systems.
  3. Experience working in remote, collaborative, and agile environments.
  4. Expertise in modern development tools, version control systems, and CI/CD pipelines.
  5. Strong problem-solving skills with keen attention to detail.
  6. Excellent written and verbal communication skills, with a high standard for clarity and professionalism.
  7. Self-driven, proactive, and able to work independently in a distributed setting.
