Our client, a renowned name in the UAE, are seeking a seasoned Full Stack Developer who combines hands-on React expertise with solid Oracle and Azure cloud experience to transform a PoC into a production-grade MVP, integrating with enterprise systems and ensuring secure, cloud-ready deployment on Azure. The PoC is a workflow-based internal app for managing business requests, approvals, and delivery tracking. The frontend is built with React + Tailwind CSS, the backend with Oracle Database via ORDS REST APIs, and Azure AD (OIDC) is the target authentication mechanism.

Key Responsibilities:

• Refactor and productionize existing React + Tailwind codebase (TypeScript, Vite).
• Build a robust API layer for ORDS (Axios + React Query, retries, pagination, caching).
• Implement Azure AD (MSAL) SSO and fine-grained RBAC on the client.
• Harden CORS and request signing for ORDS; add error handling and telemetry.
• Set up Azure DevOps CI/CD with environment slots (Dev/UAT/Prod).
• Manage secrets via Azure Key Vault; use App Configuration for non-secret settings.
• Enable Application Insights (front-end telemetry, API dependency tracking).
• Document architecture, API contracts, env configuration, and handover runbooks.

Must-Have Skills:

Frontend

• React (Hooks, Context), TypeScript, Tailwind, React Router, React Query
• Vite build optimization, route-based code splitting, form libs (React Hook Form/Zod)
• Unit/integration testing (Jest + React Testing Library)

Backend

• Oracle ORDS consumption: REST patterns, pagination, filtering, ETags
• Strong SQL reading/diagnostics; ability to suggest ORDS performance tweaks (indexes, views)
• Auth flows (OIDC/JWT), secure headers, CSRF patterns for SPA + API

Azure

• Azure Static Web Apps or Azure App Service
• Azure AD / Entra ID with MSAL.js
• Azure DevOps pipelines (multi-env, approvals, gated releases)

Deliverables:

• Deployed MVP (Dev/UAT/Prod) on Azure
• Wired SSO (MSAL), RBAC, telemetry, and resilient API client.
• CI/CD pipeline(s) with environment variables, secrets, and approvals.
• Documentation: architecture diagram, env matrix, runbook, KT session.
