Description
Stackex is an AI platform that generates native React Native/Expo apps from natural language prompts, with live in-browser preview. As founding engineer, I led the initial platform development, defined the technical architecture, and drove product delivery from concept to production.
The platform combines an AI agent execution layer with per-user Docker sandbox infrastructure on Google Cloud, enabling users to build and preview mobile apps entirely in the browser.
- Built a multi-tenant sandbox platform on Google Cloud, provisioning isolated Docker environments for each user's React Native application.
- Designed a secure routing architecture using Nginx and Redis to enable browser access to application previews, Metro bundler, and development services through a single domain.
- Developed an AI agent execution framework supporting both direct code modifications and multi-step planning workflows, with execution tracing through Langfuse.
- Owned the technical architecture end-to-end: NestJS/PostgreSQL backend, AI agent execution layer, and per-user Docker sandbox infrastructure on Google Cloud.
