Below are selected case studies from my work at Bitvavo, Adyen, and ProGlove. Each one follows the same structure: why the work mattered, what the problem was, how I solved it, and the result.

Bitvavo

API docs platform

A developer portal for 8 REST, WebSocket, and FIX APIs. 73,000+ new users in the first year.

Docs strategy

Content, information architecture, and API governance as the sole technical writer.

Adyen

Terminal API reference

OpenAPI for a non-REST payment protocol.

In-person payments overhaul

Navigation cut from 67 items to 47. About 25% more section traffic.

NFC integration docs

Docs structured around user intent across card types and terminals.

Logistics API reference

Partner documentation for an API still in development.

ProGlove

Docs platform

From a minimal MkDocs site to a multi-product portal within a year.
