Amazon Vendor/Seller Analytics Dashboard

System architecture

Architecture / Flow

The practical path from source data to reliable reporting output.

Report capture

Recurring marketplace reports and email-delivered files are collected through Python/Gmail workflows.

Storage layer

Parsed report rows land in a MySQL reporting schema designed around dashboard queries.

Reporting app

A Next.js dashboard reads the reporting tables for authenticated filters, grids, charts, and exports.

Validation

Report periods, source totals, and dashboard totals are checked before stakeholders use the views.

Project Overview

Built a marketplace reporting system for recurring vendor/seller reports that were otherwise handled through manual files and email workflows. Python ingestion scripts collected and loaded reports into MySQL, while a Next.js dashboard exposed authenticated reporting views, filters, tables, charts, and export workflows.

Key Challenges

Marketplace reports arrived through recurring files and email workflows rather than one clean API
Report formats and periods could drift from the dashboard schema
Dashboard totals needed to be validated against source report totals
The client needed a custom interface beyond spreadsheets or generic BI

Results & Impact

Built report ingestion into a MySQL reporting layer
Created authenticated dashboard views with filters, grids, charts, and exports
Separated ingestion, database validation, and UI reporting concerns
Documented the reporting workflow so the system could be maintained after handoff
