Sarthak Poswal

Since February 2024 I have been a technical content writer at Kernel Apps, where I research and write about SQL, Exchange Server, Office 365 and software troubleshooting. I work with the QA and development teams to turn complex product behaviour into clear, step-by-step content for both technical and non-technical readers.

Before writing full time, I built a full-stack web application with React and Java Spring during an internship. That experience means I can read API responses, run the commands I document and spot where a procedure will break.

  View excerpt

  Request

  curl -X POST https://api.example.com/v1/auth/login \
    -H "Content-Type: application/json" \
    -d '{"email": "user@example.com", "password": "YOUR_PASSWORD"}'

  Response (200 OK)

  {
    "token": "eyJhbGciOiJIUzI1NiJ9...",
    "expiresIn": 3600
  }

  Send the token in the Authorization header of every later request: Authorization: Bearer YOUR_TOKEN. When the token expires, the API returns 401 Unauthorized. Log in again to get a new token.

• Check mailbox database health in three minutes

  Instructional video script. Audience: IT administrators.

  A two-column script that pairs what the viewer sees on screen with the narration, plus on-screen text for each command.

1. Research the topic and the reader

   I check search intent, keywords and competitor content to find out what readers are really asking and what existing articles leave out.

2. Verify with the product and the team

   I run the steps myself and confirm details with QA and developers. I use ChatGPT, Claude and Gemini for research and editing support, and I always validate the output for technical accuracy.

3. Structure before writing

   Each piece gets a clear outline: problem, prerequisites, steps, expected result and next action.

4. Write for scanning

   Short sentences, one action per step, and code or screenshots only where they remove doubt.

5. Publish, optimize and update

   I format and publish in WordPress, optimize on-page SEO, and update content when the product changes.
