5-month contract

Onsite / 21 College Street, Toronto

Justice Technology Services - Ministry of Public and Business Service Delivery and Procurement

Security Level: CRJMC

Scope

• The project will deliver a secure, user-friendly notification platform that provides real-time updates and clear instructions related to court appearances. The solution will ensure that accused individuals receive accurate, timely, and actionable information to reduce no-shows and improve adherence to court requirements.
• The Notify App project aims to improve and streamline communication for accused individuals within the judicial process, specifically targeting the first court appearance stage. This initiative addresses two critical issues:
  • Missed court appearances due to lack of timely notifications.
  • Insufficient understanding of court protocols, leading to procedural delays and non-compliance.

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).
• Dockerized 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.
