Personal IntroductionAutomation Architect · Bangladesh
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.
Built CallSaaS — a multi-tenant AI calling platform targeting Bangladesh, integrating SSLCommerz (bKash/Nagad) as a payment gateway and Groq for a zero-cost STT → LLM → TTS stack.
Launched VoiceForge AI — a full ElevenLabs-style voice generation SaaS MVP powered by XTTS v2, with a three-tier (Free/Pro/Enterprise) monetization model deployed on Vercel + Railway + Supabase.
Built AI Workforce Platform — a virtual employee SaaS for small businesses combining voice AI agents, task automation, and a management dashboard across 47 files, entirely on free-tier infrastructure.
Deployed production AI agents on GratisVPS (6GB RAM, no card required) using PM2, Groq API, and Supabase as a zero-cost hosting stack.
