    • Implement authentication and authorization best practices (OAuth, JWT, API Gateway) while supporting dynamic authentication models based on user roles and access control.

    Design and optimize database interactions using SQL / NoSQL databases (MongoDB, PostgreSQL, DynamoDB).

  • Develop CI / CD pipelines for automated API deployment using AWS services (CodePipeline, Bedrock, CloudFormation).

    • Monitor and improve API performance, logging, and error handling using Prometheus, Grafana, and ELK stack.

  • Work on AI-driven API integrations including Recommender Systems, LLM-based AI Agents, and AI-powered Image & Video Processing workflows.

    • Collaborate with front-end engineers, data scientists, and DevOps teams to ensure seamless API integration and scalable deployments.

    Requirement (Must Have)

  • years of experience in API development with GraphQL (Ariadne) and RESTful services.

    • Strong hands-on experience with (Express / , FastAPI (Python), and Golang.

  • Proficiency in API design principles, focusing on metadata-driven frameworks that allow dynamic data exposure with adaptable authentication models.
  • Experience with AWS Lambda, AWS Bedrock, and Kubernetes (EKS) for serverless and microservices architectures
  • Hands-on experience designing scalable and modular API architectures.

    • Expertise in OAuth, JWT, API Gateway, and dynamic authentication mechanisms.

    Strong knowledge of OLAP workloads and Databricks integration for API-driven data analytics.

  • Experience with SQL / NoSQL databases (MongoDB, PostgreSQL, DynamoDB).

    • CI / CD automation expertise (Jenkins, GitHub Actions, AWS CodePipeline).

    Proficiency in API testing frameworks (Postman, Newman, Jest, Mocha, PyTest).

    Strong debugging, logging, and monitoring skills (Grafana, Prometheus, ELK stack).
