Design and implement backend services and APIs (RESTful and/or GraphQL), ensuring correctness, security, performance, and maintainability.
Apply security best practices across frontend and backend systems, mitigating risks such as XSS, CSRF, CORS, and common authentication or authorization vulnerabilities.
Own features or project phases end-to-end, from requirements and design through implementation, testing, deployment, and production support.
Write high-quality, maintainable code and comprehensive unit, integration and end-to-end tests using appropriate testing frameworks.
Contribute to large-scale distributed systems, improving scalability, reliability, observability, and operational efficiency.
Participate in code reviews, design discussions, and technical reviews, applying independent judgment and offering constructive feedback.
Act as a technical resource for teammates by sharing knowledge, reviewing code, and helping improve team engineering practices.
Debug and resolve production issues, and proactively identify opportunities to improve system performance, reliability, and security.
