My Rocket.io web app already has a working skeleton, but I now need it taken from “prototype” to “production-ready.” The platform gathers market-intelligence data, generates leads, and lets me launch campaigns aimed at the United States physician-placement sector. I have wired up some REST endpoints, yet the integrations are only partially complete and the backend logic is still thin. Here is what I need completed: • API integration – connect and stabilize the external data feeds I rely on for physician lists, market stats, and email delivery. • Backend development – extend the current Node-based code on Rocket.io, build out database management (schemas, indexing, backups) in PostgreSQL, and create data-processing workflows that clean, enrich, and score incoming records automatically. • Campaign module enhancements – introduce hands-free automation that can schedule, pause, or recycle campaigns based on engagement metrics, and refine the user interface so that selecting audiences, crafting messages, and reviewing results feels effortless. Acceptance criteria 1. All APIs authenticate securely and return data that is stored, parsed, and surfaced in under two seconds per request. 2. Database operations support at least 50k new physician records per month without noticeable slowdown. 3. Campaign automation can run hourly jobs, trigger follow-ups, and log outcomes to the dashboard in real time. 4. UI updates must pass a quick usability check with me and render consistently on modern desktop browsers. If you have solid Rocket.io experience—or are confident you can dive in quickly—let’s talk about timelines and a phased rollout so I can start using the platform for my own outreach campaigns as soon as possible.
