This includes developing detailed programming specifications, user interface designs, prototypes, writing and/or generating code, compiling data driven programs, conducting unit tests and debugging code.
Assignment Deliverables:
- Detailed design and specification documents for RESTful APIs, including endpoints, request/response models, authentication, and error handling.
- Clean, scalable, and secure REST APIs built using Java and Spring Boot, adhering to best practices and company standards.
- Modular and decoupled microservices, designed and deployed independently, with clear inter-service communication protocols.
- Using APIs to develop application based on the business requirement to transform and route data.
- Comprehensive test coverage using tools like JUnit, Mockito, or Test Containers to ensure code reliability and prevent regressions.
- Efficient relational database schemas designed and implemented to support API data storage and retrieval.
- Profiled and optimized APIs for response time, memory usage, and throughput, ensuring high performance under load.
- Secure API calls with proper authentication (e.g., OAuth2, JWT), authorization, input validation, and protection against common vulnerabilities (OWASP).
- Dockized applications with configuration files, docker-compose scripts, and Kubernetes manifests (if applicable) for smooth deployment.
- Integrated monitoring (e.g., Prometheus, Grafana) and logging (e.g., ELK stack, Logstash, or Splunk) for operational visibility.
- Produce clear documentation for developed systems such as design, deployment instructions, and operational guides.
- Regular code reviews, feedback sessions, and mentorship to junior developers, ensuring code quality and knowledge sharing.
- Weekly or sprint-based status updates on development progress, blockers, and delivered functionalities.
- Timely resolution of production issues, regression fixes, and performance improvements based on user feedback and testing.
- Available for any on-call on weekend for production issues.
