I turn complex product features and developer tools into clear, user friendly documentation, guides, tutorials, and onboarding content—carefully proofread for clarity and consistency.

With a background in computer science education and full stack development, I don’t just describe products—I understand how they’re built. This means accurate, practical content that’s easy for users to follow.

I’ve contributed developer tutorials to freeCodeCamp, with a strong focus on clear, practical instruction.

What I help you achieve
• Clear user and developer documentation
• Step by step tutorials and real world workflows
• Onboarding guides that improve adoption and reduce friction
• Polished, consistent content through proofreading and editing
• Lower support burden through better documentation

What I create
•User Guides •API Docs •READMEs •Tutorials •Blog Posts •How To Articles •SaaS Onboarding Flows •Product Manuals.

My goal is to help users learn faster, build faster, and stay longer.
