• Database Management: Design, implement, and optimize database schemas and queries for both relational (e.g., PostgreSQL, MySQL) and NoSQL (e.g., MongoDB, Redis) databases.
• API Development: Develop and maintain robust, versioned RESTful or GraphQL APIs using Node.js frameworks (e.g., Express, Fastify) to power our web and mobile clients.
• Mentorship & Leadership: Mentor junior and mid-level developers, conduct thorough code reviews, and foster a culture of technical excellence.
• CI/CD & DevOps: Implement and manage CI/CD pipelines for automated testing and deployment, and leverage cloud platforms (e.g., AWS, Azure, GCP) to scale applications.
• Collaboration: Work closely with product managers, designers, and other stakeholders to translate business requirements into technical solutions.
• Troubleshooting: Diagnose and resolve complex performance, security, and scalability issues across the entire technology stack.

• API Design: Deep understanding of RESTful API design principles and experience with API consumption and integration.
• Cloud & DevOps: Demonstrable experience with at least one major cloud provider (AWS, Azure, or GCP) and familiarity with CI/CD principles and tools.
• Testing: Solid understanding of testing (unit, integration, e2e) frameworks and methodologies (e.g., Mocha, Vitest).
• Secure Development: Strong understanding of secure coding practices (e.g., OWASP Top 10) and experience implementing security best practices.

Preferred Qualifications (Nice-to-Haves)

• Experience with containerization and orchestration technologies (e.g., Docker, Kubernetes).
• Knowledge of microservices architecture patterns.
• Familiarity with infrastructure as code (IaC) tools like Terraform or Ansible.
• Experience using AI-powered development tools like GitHub Copilot or similar.
