Behind the code
From idea to a navigable product in one weekend.
The public repository shows how flows, components, and integrations were organized to get Echo running quickly — including the structure prepared for the complete audio experience.
01 · Product decisions
Technology in service of the experience
A web product
Next.js provides the application foundation, bringing the learning flows into an interface available through the browser.
AI within the learning flow
AI-assisted conversation is part of the learning experience rather than an isolated technology demonstration.
Costs kept under control
The voice experience is separated from the other flows. It is disabled in the public deployment to avoid API costs.
A verifiable implementation
The published product and open repository expose the application structure, components, and decisions used to move from idea to working software quickly.
02 · Learning
A functional demo with explicit boundaries
The project showed how a focused scope and straightforward architecture can validate a working product quickly, while preserving a useful demo when a cost-dependent integration cannot remain continuously available.
