Case Study

Designing a Modular Document Platform

Next.js · Go · PostgreSQL · JWT/OAuth · PDF Pipeline

Executive Summary

Built a modular document platform where uploads, workspaces, metadata, and downloads all follow one clear flow. Shared layouts and reusable components kept the product scalable as new tools were added.

The Problem

Each PDF tool had different inputs, outputs, and validation rules.
Building separate pages for every tool would have created a fragile, hard-to-maintain codebase.
Users needed a consistent experience across many document operations.

Architecture & Approach

1
Shared tool layout with common upload, workspace, and download patterns
2
Tool-specific workspaces built on reusable UI and state primitives
3
Backend services designed around a flexible processing pipeline
4
Dynamic metadata and route-driven configuration for tool pages

Challenges & Trade-offs

Keeping many tools consistent without repeating the same page logic

Preserving flexibility for special tools like URL input and multi-file workflows

Outcomes & Results

A single product shell that made many tools feel like one platform
Less duplication and easier maintenance as the toolset expanded
