Complex Tech Stack Project

Frontend ( FULL STACK ) — Next.js 16 (App Router) + React 19 + TypeScript SPA, with server-side route handlers proxying all privileged calls. Deployed on AWS Amplify. Serverless backend — AWS CDK v2 (Python) monorepo: Lambda, DynamoDB (single-table design), AppSync GraphQL, IoT Core MQTT (real-time), Cognito, EventBridge. AI service — FastAPI (Python 3.12) + Celery + Redis + PostgreSQL, integrating xAI Grok (and Venice/Kimi), RunPod (image gen), and ElevenLabs (voice). Deployed on AWS App Runner. 3+ years full-stack, production ownership (not just greenfield). TypeScript + React + Next.js (App Router, server components, route handlers). Python for backend services — comfortable in both FastAPI and Lambda handler code. AWS serverless, hands-on: Lambda, DynamoDB, API Gateway/AppSync, Cognito, IAM. Ideally CDK (we use Python CDK). GraphQL (schema, resolvers) and relational SQL (PostgreSQL). Solid debugging across service boundaries — HMAC-signed webhooks, event buses, async jobs. Git, code review, writing tests. Reads other people's code without complaint. Comfortable with adult content.
