Documentation Engineer & Technical Writer · Developer Education · Blockchain & Security Writing
Brazil · Remote · Open to documentation and developer-education work
I turn complex blockchain protocols, smart contracts, and security concepts into clear, maintainable documentation that developers actually use. In this industry since 2020, from a journalism and editorial path to docs-as-code, engineering, and security self-learning.
- Documentation engineering: docs-as-code (Git + Markdown + pull requests), information architecture, docs health checks, section rebuilds, API and SDK documentation
- Developer education: tutorials, research articles, guides, workshops, onboarding paths, education-shaped DevRel
- Security writing: technical explainers, research summaries, postmortems (writing only, not audits)
- 0xramp labs: co-builder, docs and partner SDK lead for a non-custodial fiat-to-crypto ramp, live in production
docs.0xramp.app · 0xramp-docs · 0xramp-sdk (TypeScript) - thecoding.dev: my services site, overhauled docs-as-code in the open; the buyer-path overhaul (issues, PRs, phases) is public and part of the portfolio
- Dash: two sponsored research deep dives, a repeat commission from the same client: GroveDB deep dive and Dash Orchard explainer
- Quai Network: Quai Starter Pack, sponsored quickstart guide with tested steps
- MultiversX: official blog post on the Andromeda upgrade, plus a developer education pilot in Brazil (first MultiversX meetup, Portuguese newsletter, mentorship support)
- HackenProof: guest article on bug bounty hunting
- NEAR: protocol research on thecoding.substack.com, including Storage Cost Attacks on NEAR
- Nano Foundation: technical education articles on the official blog during my community lead tenure

If you want to discuss documentation or developer education work, send a brief: the product, the surface that hurts, and your timing. Five lines are enough.
Building documentation that scales with engineering teams.
