  • Work on database design and optimization (PostgreSQL/MongoDB) to store attributes, user data, and generated sheets with efficient querying.
  • Support implementation of secure authentication (JWT/OAuth), file handling (S3 or similar object storage), and async processing queues for high-volume image analysis.
  • Contribute to monitoring, logging, error handling, and basic automated tests to maintain reliability and scalability for growing upload volumes.
Required skills and qualifications
  • Pursuing or recently completed Bachelor’s in Computer Science or equivalent.
  • Academic or personal project experience in backend development using Python (FastAPI/Django/Flask), Node.js (Express/NestJS), or Java Spring Boot.
  • Basic understanding of databases (SQL/NoSQL), REST APIs, and cloud platforms (AWS/GCP) plus familiarity with Docker and CI/CD concepts.
  • Interest or exposure to AI/ML integration, image processing libraries (OpenCV/Pillow), and API documentation tools (Swagger/Postman).
  • Proficiency with Git, unit/integration testing basics (Jest/Pytest), and a strong problem-solving and communication mindset.
What you will gain
  • Hands-on experience building production-grade backend services for an AI-driven eCommerce tool.
  • Mentorship from senior engineers and exposure to best practices in APIs, databases, and cloud deployment.
  • Performance-based stipend, internship certificate, and potential full-time offer upon successful completion.
