Backend Developer Needed: FastAPI + Astrology API + Gemini Pro Context Injection

💎 KP-MASTER 💎 [READ INSTRUCTION BEFORE BIDDING] We are building a premium, conversational AI Astrology Web App specializing strictly in KP (Krishnamurti Paddhati) and Horary (Prashna 1-249) systems. The frontend user UI layout is handled. We need an elite, independent backend developer to build the secure data calculation pipeline and LLM orchestration layer in Python (FastAPI). SCOPE OF WORK: 1. Data API Integration: Connect our backend to a premium Vedic astrology API (e.g., ProKerala or AstrologyAPI.com) to fetch precise Placidus 12 House Cusps and planetary Sign, Star, and Sub-Lords. 2. Horary Lookup Table: Implement a strict programmatic lookup for numbers 1 to 249 to instantly generate the Ascendant profile, combined with current transit positions. 3. LLM Orchestration: Take the structured JSON data from the astrology vendor, wrap it inside a strict system prompt (which will be provided in a decoupled config file), and pipe it into the Google Gemini 1.5 Pro API using a streaming text-response model. 4. Session Memory Layer: Implement a lightweight database or state management buffer (Redis or Postgres) to retain ongoing conversation context so the AI remembers details revealed mid-chat (like marital status and children) without losing track of the original natal chart data. QUALIFICATION RULE: You must start your application message with the exact phrase "I AM A KP MASTER". If you do not include this at the very top of your bid, your proposal will be automatically archived and deleted. Please provide examples of prior API-to-LLM context injection or AI chat application work. BUDGET: ₹45,000 (Fixed Price - Milestone Based) TIMELINE: 5 Days to Delivery.
