I help companies turn complex products into clear documentation, scalable knowledge bases, and strong technical content. With 5+ years of experience, I’ve worked with 40+ companies across SaaS, B2B software, fintech, AI, robotics, EdTech, compliance, and operations-heavy products. My work spans both documentation systems and technical content writing, from knowledge bases, API docs, onboarding guides, and internal SOPs to technical blogs, product explainers, whitepapers, and thought leadership articles. Today, documentation does more than inform users. It also shapes how AI agents, copilots, chatbots, semantic search systems, and LLM-powered assistants understand your product. That’s why I focus on content that is clear for users, useful for teams, and structured well enough for AI systems to retrieve from reliably. What I help companies with User onboarding - helping users get set up and reach value faster Feature adoption - making key capabilities easier to understand and use Help centers and knowledge bases - reducing support load through stronger self-service API and developer documentation - making integrations easier to implement Internal documentation - SOPs, workflows, runbooks, and operational guides Technical blogs and articles - useful content for developers, technical buyers, and product users AI-powered support systems - improving retrieval quality for chatbots and support agents Why clients hire me I build systems, not just pages. I create structured knowledge systems that are easier to use, maintain, and scale. I can write for both users and technical audiences. That includes user guides, API docs, developer references, technical blogs, and product explainers. I make technical content useful, not bloated. Whether it’s a knowledge base article or a long-form blog, my goal is the same: make it clear, practical, and worth reading. I make documentation AI-ready. I help companies structure documentation so tools like Intercom Fin, Mintlify AI, Claude, Cursor, Codex, and other agent-based systems can retrieve and use knowledge more accurately. That often includes improving: Information architecture Structured Markdown Workflow documentation Troubleshooting paths Retrieval-friendly FAQs Machine-readable layers such as llms.txt, skill.md, and other agent-friendly documentation patterns Platforms and tools I work with Documentation / KB Platforms: Zendesk, Intercom, Mintlify, Confluence, GitBook, Document360, Freshdesk, Notion, Help Scout, Guru, Zoho Desk, Eniston, Helpjuice AI / Support Tools: Intercom Fin AI Agent, Zendesk AI, Freshdesk Freddy, semantic search systems, AI-assisted retrieval workflows Technical / Workflow Tools: Markdown, JSON, API documentation workflows, Git-based docs, Google Docs, Canva, Loom, screen recording tools Highlights of my experience I’ve helped companies such as McCain Foods, Phonely, Alternative Payments, Aragorn AI, Energy Robotics, Neword, ENTR Technologies, MenuLogic K12, Solaris Offgrid, Venue Smart, Qonnect, Compliance Scorecard, CodeRabbit, Stream, EloqData, and Cline. Examples of my work: 1. Phonely - built and maintained documentation for workflows, integrations, AI systems, and API usage; structured docs for both users and AI agents 2. Alternative Payments - led a multi-department documentation migration from Google Drive to GitBook across Finance, Sales, Customer Success, and Technical teams 3. Neword - created the Intercom knowledge base from scratch and helped train and optimize Intercom Fin AI Agent through simulations, response reviews, and knowledge gap fixes 4. Solaris Offgrid - worked as a Technical Support Engineer and Technical Writer, owning onboarding docs, support guides, troubleshooting content, and API documentation 5. CodeRabbit, EloqData, Stream, and Cline - wrote technical content covering software development, APIs, DevTools, AI workflows, and product education Services I offer Documentation & Knowledge Bases Help center creation and restructuring Knowledge base architecture User guides and onboarding flows Internal SOPs and runbooks API & Technical Documentation REST API documentation SDK and developer guides Integration and workflow documentation Release notes and technical updates Technical Content Writing Technical blog posts Product explainers Thought leadership content Whitepapers and technical articles AI-Ready Documentation Documentation structured for AI retrieval Support content for chatbots and agents Knowledge base optimization for self-service and AI support If you need someone who can create documentation, knowledge systems, API docs, and technical content/articles that actually helps people understand and use your product, I can help.
