# Production

### **User Journey**

Users can vizualize jobs available to them on their dashboard. Some jobs may not be available to all users, based on their profile.

There are 4 types of jobs available:

* Data collection: Voice, Photo and Videos
* Surveys: answer questionnaires
* Social media: visit a social media page and engage
* Project review: visit a website or download an app and complete actions

A job can consist of several tasks, which must all be completed before the user can validate their production. 

Jobs can either be "unique", which means a user can only complete the job once. Or they can be "multiple" which means a user can submit the same job several times.

### **UX highlights**

Ta-da's production interface has been built around key principles, to balance scalability and user-experience with

* deeply customizable tasks, ensuring guidelines can be adjusted to each campaign
* Adaptive UX based on user behavior and performance.
* Support user-specific contents, based on past behaviour, performance or profile
* Light frameworks and responsive UIs to maximize accessibility across continents

### **Back-end highlights**

To optimize throughput and reduce latency, our back-end is designed to support:

* **Smart routing**: ensuring the right user gets the right task based on skill, availability, or past performance.
* **Concurrency handling**: when millions of microtasks are being processed in parallel, race conditions, double submissions, or stale task serving can degrade performance.
* **Fraud detection models** (e.g., device fingerprinting, behavioral analysis),
* **KYC-lite mechanisms** for sensitive data and **trust scoring** systems for long-term integrity.
* Robust **metadata pipelines**, **version control for datasets**, to maintain links between raw input, annotations, and audit logs.
