Job Title: Next.js Developer Needed: AI-Powered EdTech PWA (Math Logic Engine) Job Description: We are looking for a high-velocity Full-Stack Developer to build the MVP of Triune AI, a mobile-first PWA targeting the Singapore PSLE Math market. The architecture is already defined. We need you to "glue" the components together into a functional, cinematic "Command Bridge" learning interface. The Tech Stack (Mandatory): Frontend: Next.js (App Router), Tailwind CSS. Backend/Auth/DB: Supabase (Auth, Postgres, Edge Functions). Payments: HitPay API (Credit Card & PayNow integration). AI Orchestration: DeepSeek-R1 (Logic/Generation) and Qwen-2.5-Flash (Mentor Chat) via OpenRouter or DashScope. Hosting: Alibaba Cloud (Singapore) or Vercel. Core Features to Build: Mission HUD: A dark-mode, cinematic dashboard where students track "Gold Nodes." The Logic Loop: A system where DeepSeek-R1 generates a P6 Math problem/solution, and the student's answer is verified against that logic to unlock a node. Verbal Mastery (Basic): Integration with the browser’s native Mic-to-Text for student responses. The Harmony Protocol: A simple 45-minute countdown timer that locks the mission for a 10-minute rest period. Automated Social Pulse: A script to auto-post "Mastery Achievements" to a social media handle (e.g., via Buffer or simple webhook). HitPay Gateway: Automated unlocking of the "30-node refueling" cap upon successful PayNow/CC payment. Budget & Timeline: Fixed Price: SGD 1,000 (Milestone-based). Timeline: 14 Days. Requirements: You must be comfortable working with provided AI system prompts and a pre-defined logic flow. To Apply: Please mention your experience with Next.js + Supabase and your familiarity with integrating DeepSeek or Qwen models.
