5 Hardest Engineering Challenges I Solved Building GoPdfSuit and How It Cuts PDF Infrastructure Costs by 92%

PDF generation sounds boring until you're deep in archival standards, cryptographic signing, and cross-language memory bridges at 3am. Building GoPdfSuit - a Go-based PDF generation suite - meant solving five genuinely hard problems. Here's what they were, and why the result is dramatically cheaper than every commercial alternative. The Cost Problem First Before the technical deep-dive, here's why this matters beyond engineering curiosity. Infrastructure comparison for 1.5 million PDFs/day: Arch
