How I built a commercial proposal bot using pure stdlib and headless Chrome

A freelance designer shares their experience in automating the routine task of creating commercial proposals. Previously, the process of preparing estimates, layout, and document export took up to three hours. The author developed a Telegram bot that automates this cycle: after answering seven questions, the system generates a ready-made PDF file containing estimates, timelines, and case studies. The article details the technical implementation, including the use of standard libraries, PDF rendering via headless Chrome, image processing for case covers, and the integration of a mini-app. The author also shares practical tips on maintaining the bot and summarizes two months of usage, highlighting significant time savings. This case study demonstrates how simple automated solutions can help optimize the workflow for independent professionals.
