Technical Writer | SaaS, API Docs, Help Center & Knowledge Base

Clear documentation is not just support content, it directly impacts product adoption, developer experience, onboarding speed, and customer retention. I help SaaS and AI companies turn complex products into documentation that users can actually follow. With 10+ years of experience in technical communication and software documentation, I specialize in creating structured, developer-friendly, and scalable documentation for SaaS platforms, APIs, AI workflows, low-code/no-code products, and enterprise applications. I work closely with engineering, product, support, and DevRel teams to build documentation that stays aligned with fast-moving products. My focus is not only writing content, but building documentation systems that improve usability, reduce confusion, and support product growth. ✔Services I Provide 🔹Developer & API Documentation 🔹REST API Documentation 🔹OpenAPI / Swagger Documentation 🔹SDK & Integration Guides 🔹Authentication & Webhook Documentation 🔹Developer Portals & API References ✔SaaS & Product Documentation 🔹User Guides & Feature Documentation 🔹Help Centers & Knowledge Bases 🔹Product Onboarding Documentation 🔹Workflow & Configuration Guides 🔹Release Notes & Internal Documentation ✔AI & Platform Documentation 🔹AI Product Documentation 🔹Conversational AI & Agent Workflow Documentation 🔹Prompt & Workflow Documentation 🔹AI Integration & Automation Guides 🔹Low-Code / No-Code Platform Documentation ✔Documentation Operations 🔹Docs-as-Code Setup 🔹Documentation Audits & Content Revamp 🔹Information Architecture 🔹Documentation Migration & Restructuring 🔹SEO Optimization for Help Centers 🛠 Tools & Technologies 📘 Documentation Platforms: Confluence, MadCap Flare, GitBook, Document360, Docusaurus, MkDocs, Sphinx, AEM 🔌 API & Developer Tools: Swagger, OpenAPI, Postman, Stoplight, Redocly, Readme, REST APIs, GraphQL 📄Formats & Standards: Markdown, HTML, CSS, AsciiDoc, DITA XML 🤝 Collaboration & Workflow: GitHub, Jira, Slack, Microsoft Teams, Agile/Scrum 🎥Video Tutorials & Product Demos: Camtasia, screen-recorded walkthroughs, onboarding tutorials I’ve worked on documentation projects for SaaS platforms, enterprise systems, AI-driven applications, and integration-heavy products across multiple domains.
