Why Stripe could not produce the invoices we needed for IGIC, and how we generate customer-facing PDFs from structured document data.

A practical architecture framework for file processing pipelines: typed outputs, failure boundaries, retries, observability, and fewer integration seams.

Generate XLSX, CSV, and Markdown spreadsheets from a single API call. Structured JSON in, formatted files out.

Generate book covers with custom typography, images, and print-ready dimensions. KDP-compatible output from one API call.

Multi-vendor stacks vs unified platforms — integration time, credential sprawl, billing reconciliation, and concrete TCO calculations for a typical 5-project ag

Generate manuscripts, covers, marketing banners, and social media assets for self-publishing with a handful of API calls instead of a dozen tools.

When to pipeline, when to parallelize, and how to handle errors across chained API calls.
