• Handle XML data workflows and apply XSD schema validation in backend systems
• Work with MongoDB, Mongoose, and Prisma ORM for efficient data management
• Manage authentication using JWT and bcryptjs
• Integrate third-party services: AWS S3 (file storage), Stripe (payments), Twilio (SMS), Nodemailer (emails)
• Handle file uploads securely using Multer and AWS SDK
• Generate documents using tools like pdfkit, puppeteer, and marked
• Write unit/integration tests, perform code reviews, and follow clean architecture practices

• Monitor application performance using tools like New Relic and Winston logging

   

Requirements

• 3+ years of professional experience in frontend development with React and TypeScript
• 3+ years of backend development experience using Node.js and Express
• Strong understanding of REST APIs, JSON/XML, and full-stack integration
• Practical experience working with XML/XSD validation

• Familiarity with containerized environments (Docker)

   

Nice to Have

• Experience with form-heavy interfaces, dashboards, or workflow-based UIs
• Familiarity with Redis for caching or real-time use cases
• Experience working in microservices architecture
• Understanding of accessibility (WCAG), responsive design, and performance optimization
