The role involves building responsive, high-performance web applications, developing scalable REST APIs, integrating data stores (e.g., MongoDB), and implementing secure authentication/authorization flows. Collaboration, clean code practices, and quality delivery are key.

Key Responsibilities

Frontend (ReactJS)

• Develop new user-facing features using React.js and modern JavaScript (ES6+).
• Build reusable components and front-end libraries for future use.
• Translate UX designs/wireframes into high-quality code; ensure responsive UI across browsers/devices.
• Optimize components for maximum performance and maintainability.
• Implement state management patterns using Redux / Context API where appropriate.

Backend (NodeJS)

• Design and develop scalable Node.js services and Express.js REST APIs.
• Implement secure authentication and authorization (e.g., JWT, OAuth concepts).
• Integrate with databases (e.g., MongoDB) and external systems via APIs.
• Ensure API performance, reliability, error handling, and logging.

Dev Practices / Collaboration

• Work closely with product owners, designers, QA, and DevOps teams to deliver end-to-end features.
• Participate in code reviews, enforce coding standards, and contribute to continuous improvement.
• Use Git-based version control and collaborate using branching strategies.

Required Skills

• Strong proficiency in JavaScript (ES6+), including DOM manipulation and JavaScript object model.
• Strong experience with React.js and its core principles (hooks, component lifecycle, component architecture).
• Experience with React workflows and state management (e.g., Redux / Flux patterns / Context API).
• Hands-on backend development using Node.js and Express.js.
• Experience building and consuming RESTful APIs.
• Knowledge of modern authorization mechanisms such as JWT (OAuth familiarity preferred).
• Familiarity with front-end build tools (Webpack/Babel/NPM or equivalent).
• Working knowledge of databases such as MongoDB (and schema design basics).

Good to Have (Preferred)

• TypeScript experience.
• Cloud exposure to AWS (e.g., EC2, S3, Lambda, API Gateway, DynamoDB) and/or serverless patterns.
• CI/CD familiarity and basic DevOps understanding.
• Experience with microservices / event-driven design.
• Domain exposure (e.g., Healthcare) is a plus.

Soft Skills

• Strong communication and collaborative problem-solving mindset.
• Ability to understand business requirements and translate them into technical solutions.
• Ownership mentality; ability to work as an individual contributor when required.

Optional: Interview Focus Areas (Quick Checklist)

(These are recommendations based on typical full-stack expectations; use as needed.)

• React fundamentals (hooks, component patterns, performance)
• State management (Redux/Context)
• API design (REST, validation, error handling)
• Auth (JWT flows, role-based access)
• Node/Express patterns, async, middleware
• DB basics (MongoDB queries/indexing)
• Testing basics, Git workflow
