The Mind Behind
the Automation

Personal Introduction Automation Architect · Bangladesh
Suvon Roy
Suvon Roy · Bangladesh

I'm Suvon Roy, a Python Full-Stack Developer and CSE student at Dhaka International University. I specialize in building systems that most developers avoid — navigating anti-bot measures, CAPTCHA walls, and complex automation workflows.

Beyond Python, I architect powerful n8n automation workflows — from AI video generation pipelines to Facebook bots, YouTube automation, and intelligent email scrapers. My work sits at the intersection of precision engineering and creative problem-solving.

Based in Bangladesh. Available for remote work worldwide via Fiverr, Upwork, and direct contracts.
