Specializing in AI-driven solutions that transform operations, optimize workflows, and drive measurable ROI
This is not a typical tech journey...
I'm an operator-turned-engineer who learned to code out of desperation—and built systems that now run in production for real teams.
My Journey:
- 🌾 Born in a rural village in Bangladesh (no electricity, cycled 6 miles through mud to school)
- 🍽️ 10 years in F&B operations—drowning in 40-hour payroll tasks, attendance fraud, messy spreadsheets
- 💔 2023: My mother was given 3 days to live (terminal cancer)
- 🤖 Used AI to save her life—fed medical reports into ChatGPT, discovered a cure doctors missed
- 💰 Spent my entire crypto savings (170x gains) on her treatment
- 🎉 Today, she's 100% cancer-free without chemotherapy
- 🚀 That moment changed everything
Now? I build production-grade AI automation that turns operator pain into automated profit.
