Create data aggregation in mongo.js / express.js
There is an API on Express + Mongo
In Mongo, there are tables:
1. User visits to the site (timestamp + url they visited + other details)
2. Campaigns (which advertising campaign they came from)
The connection between users and campaigns is through GET parameters within the URL that the user visits.
For example -
Campaign X is identified by the parameter "specialParam".
User Y visited on Jan 1, 2025, the link www.ourapp.com/some-page?specialParam
Therefore, the user came through ad campaign X.
An API endpoint with aggregation is needed, providing statistics on campaigns, as shown in the attached screenshot
Conversions - "purchases" by users, how to determine conversion will be discussed in more detail, not in the description.
Sessions - all visits within a half-hour period count as 1 "session". When the half hour expires, it counts as the next one.
Total entries - how many visits there were from the campaign over a period of time
Avg.pages - average value

I am interested in your task of implementing an API for aggregating statistics on advertising campaigns based on data in MongoDB. I have experience working with Node.js/Express and MongoDB, which allows me to effectively handle large volumes of data and implement similar functionalities.
What will be done:
API for aggregating campaign statistics – creating an endpoint for collecting statistics on campaigns, specifically:
Total entries – total number of entries from the campaign.
Sessions – counting user sessions lasting up to 30 minutes.
Avg. pages – average number of pages visited by a user per session.
… Conversions – we will discuss the methodology for determining conversions after clarifying the details (based on purchases or other actions).
Data aggregation – connecting GET parameters to identify the advertising campaign and linking to user actions.
🛠 Technologies I will use:
Node.js and Express for creating the API.
MongoDB and aggregation queries for statistics.
Possible use of sessions to calculate the time period between user entries.
I am ready to discuss the details and estimate the timeline after receiving more detailed information regarding conversions.
I look forward to your feedback to clarify technical aspects!

I have experience working with MongoDB and APIs. I understand the task regarding data processing from tables: information about user events on the website, as well as the connection between users and advertising campaigns through GET parameters.
I am ready to develop the necessary functionality for the proper storage, processing, and analysis of this data, as well as to set up interaction between MongoDB and the API for optimal execution of all tasks.
I would be happy to discuss the details and start working on the project.
