I built an automation system

I built an automation system that connects Telegram, n8n, Flask, and Playwright to simplify a complex browser-based workflow for field users.

The system allows users to interact with a Telegram bot instead of manually navigating a slow legacy portal. In the background, the bot manages browser automation, session handling, form submissions, and user-specific workflows automatically.

One of the main technical challenges was handling multiple browser sessions simultaneously without conflicts. Each user gets an isolated headless browser session with secure state management and automatic expiration handling.

The workflow also includes human-in-the-loop captcha solving. The bot sends the captcha image to the user, waits for the response, and then continues the automation process seamlessly.

Tech stack: • Playwright for browser automation • Flask for backend APIs and session management • n8n for workflow orchestration • SQLite for lightweight persistent storage

This project gave me hands-on experience building scalable automation systems that combine messaging platforms, backend services, and browser-level scripting for real-world operational workflows.
