Job description

• Theproject will deliver a secure, user-friendly notification platform thatprovides real-time updates and clear instructions related to courtappearances. The solution will ensure that accused individuals receiveaccurate, timely, and actionable information to reduce no-shows andimprove adherence to court requirements.

• Missedcourt appearances due to lack of timely notifications.
  
• Insufficientunderstanding of court protocols, leading to procedural delays andnon-compliance.
  
• Detaileddesign 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, adheringto best practices and company standards.
  
• Modularand decoupled microservices, designed and deployed independently, withclear inter-service communication protocols.
  
• UsingAPIs to develop application based on the business requirement to transformand route data.
  
• Comprehensivetest coverage using tools like JUnit, Mockito, or Test Containers toensure code reliability and prevent regressions.
  
• Efficientrelational database schemas designed and implemented to support API datastorage and retrieval.
  
• Profiledand optimized APIs for response time, memory usage, and throughput,ensuring high performance under load.
  
• SecureAPI calls with proper authentication (e.g., OAuth2, JWT), authorization,input validation, and protection against common vulnerabilities (OWASP).
  
• Dockerizedapplications with configuration files, docker-compose scripts, andKubernetes manifests (if applicable) for smooth deployment.
  
• Integratedmonitoring (e.g., Prometheus, Grafana) and logging (e.g., ELK stack,Logstash, or Splunk) for operational visibility.
  
• Produceclear documentation for developed systems such as design, deploymentinstructions, and operational guides.
  
• Regularcode reviews, feedback sessions, and mentorship to junior developers,ensuring code quality and knowledge sharing.
  
• Weeklyor sprint-based status updates on development progress, blockers, anddelivered functionalities.
  
• Timelyresolution of production issues, regression fixes, and performanceimprovements based on user feedback and testing.
  
• Availablefor any on-call on weekend for production issues.
