How It Works
1. Triggered by Telegram: A user sends a PDF resume to a designated Telegram bot. 2. Authentication & Filtering: The workflow authenticates the user and ignores `/start` messages. 3. PDF Download & Text Extraction: The PDF file is downloaded from Telegram, and its text content is extracted. 4. AI-Powered Data Parsing: The extracted text is fed to an OpenAI GPT-4 model, which, guided by a structured output parser (LangChain), extracts resume details (personal info, employment history, education, projects, volunteering, skills) into a JSON format. An auto-fixing parser ensures data quality. 5. HTML Formatting: Each section of the extracted structured data is converted into a readable HTML snippet using custom JavaScript code. 6. Consolidate & Prepare Output: All HTML snippets are merged, and then encoded into base64 to create a complete `index.html` file. 7. PDF Generation: This HTML file is sent to a self-hosted Gotenberg server, which converts it into a professional PDF document. 8. Deliver via Telegram: The generated PDF resume is sent back to the original Telegram user.
