environments.
● Manage environment variables and configuration files securely.
● Basic understanding of deployment on VPS/cloud platforms will be an added advantage.
● Validate deployments with functional testing and issue resolution.
Technical Leadership & Team Guidance
● Guide junior and mid-level developers in technical implementation, code structure, and
best practices.
● Review code and provide constructive feedback to maintain code quality.
● Help developers resolve technical blockers and debugging issues.
● Suggest better approaches for architecture, API design, database structure, and
frontend implementation.
● Ensure the team follows proper coding standards, Git workflow, and project structure.
● Support the Team Lead/Project Manager in technical planning, estimation, and feasibility
analysis.
● Share knowledge with the team and help improve overall development practices.
● Take ownership of complex modules and support other developers in delivering their
assigned tasks.
Next.js Knowledge - Added Advantage
● Experience with Next.js will be preferred.
● Understanding of SSR, SSG, routing, API routes, middleware, and performance
optimization in Next.js will be a plus.
Required Skills
● Strong hands-on experience with MongoDB, Express.js, React.js, and Node.js.
● Good command over backend development using Node.js and Express.js.
● Strong understanding of REST API development and integration.
● Experience with MongoDB schema design, aggregation, indexing, and optimization.
