Application Development and Feature Delivery

Design, develop, test, and deploy new features and enhancements across front-end (ReactJS) and back-end (Python/FastAPI) layers of CBO applications.

Build and maintain RESTful APIs using FastAPI, ensuring proper validation, error handling, versioning, and documentation (e.g., OpenAPI/Swagger).

Develop responsive, accessible front-end interfaces using ReactJS, adhering to CBO UX standards and Section 508 accessibility requirements.

Implement and manage data models, queries, migrations, and stored procedures within PostgreSQL databases, with attention to performance and data integrity.

Trunk-Based Development and Collaboration

Operate within CBO’’s trunk-based development workflow, committing small, incremental changes frequently to the main branch to reduce integration risk and maintain a releasable codebase.

Participate in code reviews, providing and receiving constructive technical feedback to maintain code quality and consistency.

Collaborate with CBO engineers, product owners, and analysts to understand requirements, refine user stories, and deliver working software iteratively.

Adhere to CBO’’s branching, commit, and merge standards, including the use of short-lived feature branches and feature flags where applicable.

Containerization and Cloud Deployment

Package applications and services using Docker, maintaining clean, minimal, and reproducible container images.

Support deployment of containerized workloads to AWS environments (e.g., ECS, EKS, or equivalent managed services), working within existing cloud infrastructure patterns established by CBO’’s infrastructure team.

Demonstrate working knowledge of AWS services relevant to application hosting and operation, including but not limited to EC2, S3, RDS, CloudWatch, IAM, and VPC networking concepts

Collaborate with CBO infrastructure staff on environment configuration, secrets management, and cloud resource usage. The Contractor is not expected to serve as a dedicated IaC or CI/CD engineer but should be comfortable working within automated deployment pipelines and contributing pipeline-compatible code.

Maintenance, Bug Fixes, and Technical Debt Reduction

Investigate, diagnose, and resolve application defects, performance issues, and security vulnerabilities across all layers of the stack.

Proactively identify and address technical debt, refactoring code to improve maintainability, readability, and test coverage

Monitor application behavior and logs (e.g., via AWS CloudWatch or equivalent) and respond to operational issues as needed.

Testing and Quality Assurance

Write and maintain automated unit, integration, and regression tests for both back-end (pytest or equivalent) and front-end (Jest, React Testing Library, or equivalent) code.

Ensure new features and bug fixes are accompanied by appropriate test coverage prior to merge.

Participate in functional and user acceptance testing in coordination with CBO stakeholders.

Documentation

Maintain accurate, up-to-date technical documentation for all developed systems, including API documentation, data model diagrams, architecture decision records (ADRs), and developer setup guides.

Document operational procedures, environment configurations, and known issues in CBO’’s designated knowledge management platform.
