Backend Python/Node.js Developer for JSON Data Ingestion and Template Automation Script

*"We are launching a lightweight, backend-driven business data processing script. The complete structural variable frames, data-mapping logic sequences, and API contracts are 100% written and finalized by our management team. We require an independent, senior backend engineer to code the server plumbing. Core Abstract Technical Workflow: DATA INGESTION: Establish a server-side Python/Node.js pipeline connecting to an external JSON endpoint via Websockets or Webhooks to fetch live real-time text streams. TEMPLATE FILTERING: Read incoming multi-variable JSON data fields and automatically inject specific string variables into pre-set text templates based on conditional logic. METRIC RE-ROUTING: Build an automated backend loop that automatically switches data processing speed from an 8-minute cycle down to an intensive 4-minute hyper-loop based on conditional data triggers. Development Milestones & Escrow Allocations: Milestone 1 (€250): Day 1–4. JSON Text API connection verified and mapping accurately to local server template placeholders. Milestone 2 (€250): Day 5–7. Automated conditional hyper-loop engine verified. Final clean Python script documentation and repository handover to our private cloud. Strict Operational Rules: All technical documents and repository keys are proprietary and shared under an NDA. Development occurs strictly within our private repository. To apply, you must answer the technical screening questions below. Generic automated agency applications will be deleted instantly."* 1. "How do you design a server-side loop to securely manage automated real-time text streams without causing database memory leaks or latency delays?" 2. "What protocol do you use to drop a permanent, secure authentication cookie into a mobile browser cache to enforce an absolute single-device login restriction?" 3. "Please show an example or past work you have done successfully using an external API JSON data stream or text-to-speech connection." 4. "Are you available to sign a strict confidentiality agreement, work natively within our private repository, and begin development immediately?"
