Our fast-growing SaaS product automates business workflows, and the next release centres on fresh functionality rather than patching old code. I need to add two categories of integrations: • Social-media APIs (e.g., Facebook, LinkedIn, X/Twitter) • External third-party data sources relevant to marketing and analytics The work spans the full stack. On the back-end you’ll stand up robust, well-documented endpoints, manage auth flows (OAuth 2.0, webhooks, rate-limit handling), and ensure data is normalised for our existing micro-service architecture. On the front-end you’ll surface the new data in a React-based dashboard so users can trigger automations without leaving the app. Acceptance criteria • Successful OAuth connection and token refresh for each provider • Real-time or scheduled data sync displayed in our UI without blocking other features • Clean, unit-tested code that fits our current TypeScript/Node pipeline and CI suite • Swagger/OpenAPI docs updated so internal teams can extend the endpoints easily Access to our GitHub repo, staging environment, and API keys will be provided after kickoff. Deliverables are pull requests ready for code review and a short hand-off walkthrough video.
