Most technical writers haven't shipped the product they're documenting. I have. I'm a backend engineer (Python, Django, distributed systems at Deloitte USI) and the solo founder of APIEngine — a developer-focused BaaS where I wrote every endpoint, every doc page, and every SDK guide myself. So when I write API documentation for your team, I'm writing it the way I'd want to read it as the developer integrating it at 2am. My approach: Explanation first. Marketing second. Complex systems get broken into structured, step-by-step guides developers can actually follow — not marketing copy dressed up as documentation. What I write: - API documentation (REST, OAuth, JWT, webhooks) - SDK guides and integration walkthroughs - Developer portals and reference docs - Technical blog posts (backend systems, AI, architecture) - System design and architecture write-ups Stack I write about with real fluency: Python, Django, DRF, FastAPI · Node.js · PostgreSQL, Redis · GCP, Docker · REST, OAuth 2.0, JWT · OpenAPI/Swagger · Markdown, GitHub Why this matters for your project: I won't ask your engineers to explain what JWT is. I won't write docs that need a second pass to fix technical inaccuracies. I won't pad word counts. I'll ask the questions a developer would actually have, and write the doc that answers them. Check the portfolio below for live samples — APIEngine's documentation, published technical articles on Medium and unite.ai, and paid client work for Polotno and Getint. If you're building a developer-facing product and need documentation that reduces support tickets instead of generating them, send me the brief. I'll tell you within a day whether I'm the right fit.
