Enterprise Reporting
Waterfall
Enterprise sales reporting & analytics platform
01
Overview
An internal enterprise platform that automates sales reporting and waterfall analytics. I worked on the Django backend and the Angular frontend: the business logic, the data-processing workflows, the reporting cycles, and the access model that scopes what each user can see.
02
Problem / Context
- Sales reporting arrived as spreadsheets and had to become trustworthy, queryable reporting output — which makes upload handling, validation and exception handling the core of the problem, not incidental plumbing.
- Reporting runs on fixed business cycles: weekly, monthly, quarterly and quarter-to-date. Each cycle has its own expectations of the same underlying data.
- Users should only see the data belonging to them and their region, so access control had to be enforced in the data layer rather than hidden in the UI.

AI Extension
AI arrived on Waterfall later, as a separate workstream layered onto an already-working platform. The reporting engine itself is conventional Django and Angular engineering — the AI work below is an addition to it, not the substance of it.
- MCP
- LangChain
- AI-powered chatbot / agent workflow implemented into the application

Outcome
- Sales reporting is automated end to end across weekly, monthly, quarterly and QTD cycles, with upload, validation, filtering, pagination and download handled inside the platform.
- Access is scoped per user and per region, so the same reporting surface serves different audiences without exposing data across boundaries.
