What You'll Do
• Design, develop, and maintain full-stack web applications using the MERN stack
• (MongoDB, Express.js, React, Node.js)
• Build and maintain scalable, secure, high-performance RESTful APIs and backend
• services.
• Develop responsive, reusable UI components in React, emphasizing usability and
• maintainability.
• Design and optimize MongoDB data models, indexes, and queries to support
• application performance and scalability.
• Collaborate with product managers, designers, and engineers to translate business
• requirements into well-scoped technical solutions.
• Ensure high-quality deliverables through testing, code reviews, performance tuning,
• and security best practices.
• Integrate and maintain third-party APIs and internal services.
• Troubleshoot and resolve issues across the stack (frontend, backend, database,
• CI/CD).
• Contribute to technical documentation, knowledge sharing, and continuous
• improvement.
• Participate in Agile ceremonies (planning, standups, retrospectives) and deliver
• iteratively.

What You'll Need
• Proven experience building production web applications using the MERN stack
• (MongoDB, Express.js, React, Node.js)
• Strong JavaScript fundamentals (ES6+), including writing clean, modern,
• maintainable code.
• Solid experience designing and implementing RESTful APIs using Node.js +
• Express.js.
• Strong React skills including hooks, component architecture,



and practical state
• management patterns.
• Working knowledge of TypeScript (able to read/write TS in a React/Node codebase).
• Experience integrating backend services with MongoDB (schemas, query
