Design, develop, and maintain the Quarkus backend REST API, including new endpoints, business logic, and security controls

Develop and enhance the React frontend, including UI components, state management, routing, and data visualization

Evolve the database schema and ORM layer (Hibernate ORM with Panache) for PostgreSQL, ensuring data integrity and performance

Implement and maintain the contract submission state machine workflow

Extend the role-based access control (RBAC) system with fine-grained permissions across users, organizations, and roles

Build and maintain containerized deployments using Podman for both development and production environments

Integrate PDF generation (HTML-to-PDF rendering) and OCR features for processing scanned contract documents

Write and maintain unit and integration tests (JUnit 5, REST-Assured)

Participate in requirements analysis and translate use cases and state machine designs into working software

Maintain and improve project documentation

Collaborate with infrastructure and operations teams on deployment, tunneling, and remote access configurations

Quarkus 3.x – Experience with the framework, including dependency injection, configuration, and extension ecosystem

RESTful API design – Building and versioning REST APIs (Jakarta REST / JAX-RS)

Hibernate ORM with Panache – Active Record and Repository patterns, entity mapping, JPQL/HQL queries

Bean Validation – Declarative validation constraints on entities and REST inputs

JWT (JSON Web Tokens) – Token generation, validation, and role-based security annotations

Background job scheduling – Implementing scheduled/cron-style tasks in a Java application

Maven – Build lifecycle, dependency management, profiles, and plugins

Frontend (React / JavaScript)

React 19 – Functional components, hooks, context API

Vite – Build tooling, configuration, and development server

React Router DOM v7 – Client-side routing and navigation

Data Visualization – Chart.js (with react-chartjs-2), Plotly.js (with react-plotly.js), and chart plugins (boxplot, treemap, sankey, wordcloud)

Material Icons / React Icons – UI iconography

Serving a frontend alongside a Java backend – Integrating npm-based build output into a Java web application

Internationalization (i18n) – Implementing and maintaining bilingual (English/French) UIs

Database

PostgreSQL – Schema design, SQL queries, JDBC configuration, and administration

MariaDB / MySQL – Secondary database support and compatibility awareness

SQL scripting – Database initialization, migration scripts, seed data management

Infrastructure & DevOps

Podman – Container image builds, container lifecycle management (build, run, stop, clean), and Containerfile authoring

Linux / Bash – Shell scripting for container and environment management

SSH / Port Forwarding – Secure remote access and tunnel configuration for development environments

GraalVM Native Image (asset) – Building and configuring native Quarkus executables

Document & File Processing

PDF processing – Parsing, text extraction, and manipulation using Java PDF libraries (e.g., Apache PDFBox)

HTML-to-PDF rendering – Generating PDF documents from HTML/CSS templates

OCR (Optical Character Recognition) – Extracting text from scanned documents using Tesseract or equivalent

Testing

JUnit 5 – Unit and integration testing

REST-Assured – HTTP API testing
