Case Study

Building a High-Performance PDF Processing Pipeline

Go · File Lifecycle · Validation · Temporary Storage

Executive Summary

Built the backend side of document processing around safe file handling, efficient transformations, and predictable cleanup so large jobs could run reliably.

The Problem

Large PDFs could consume too much memory if processed naively.
Temporary files and partial outputs had to be cleaned up safely.
Processing steps needed to stay isolated so one failure would not break the whole request.

Architecture & Approach

1
Go services with clear validation and processing boundaries
2
Temporary storage for intermediate files and generated outputs
3
Orchestrated transformation steps with explicit cleanup
4
Error handling designed for safe failure and consistent responses

Challenges & Trade-offs

Avoiding memory pressure during large document transformations

Preventing stale temporary files and partial outputs from accumulating

Outcomes & Results

A more reliable backend for long-running document operations
Cleaner file lifecycle management across the processing pipeline
