Full job description

RQ10036 - Specialized IT Consultant - Senior (APIs)

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.
