About this gig

I build custom browser automation bots in Node.js with Puppeteer or Playwright that do whatever a human can do in a Chromium browser on autopilot, reliably, at scale.


Common use cases:

- Auto-fill forms from CSV (lead submission, job applications, surveys)

- Login and scrape protected content from your own accounts

- Monitor stock or content and alert via Telegram, Slack, or email

- Daily screenshots of dashboards delivered to your inbox

- Click-through testing of multi-step user flows


What you get:

- Custom Node.js script using Puppeteer or Playwright

- Retry logic with exponential backoff and rotating IP support

- Structured logging and run reports (JSON or CSV)

- Headless or headful mode

- Source code and README with run instructions


What I need from you:

- Target URL(s) and step-by-step task description

- Test credentials if the bot logs in to your account

- Estimated run frequency (one-off, hourly, daily)


What I will not do:

- Account creation farms, fake engagement, spam

- Credential stuffing or bypass of login walls not yours

- Scraping personal data behind login walls


Ping me for a 10 minute chat to confirm feasibility before ordering.
