Specializing in AI-driven solutions that transform operations, optimize workflows, and drive measurable ROI
An engineer with 20 years behind him called me a “duct tape programmer.”
Maybe he’s right. I learned to build when life couldn’t wait—from helping save my mother’s life to shipping AI that keeps the floor running, day and night.
Hi, I’m MN Jewel (aka w3jdev), an AI Systems Architect and the founder of W3J LLC.
I build voice agents for live phone traffic, internal service agents, and the permission and cost controls around them. Five years shipping production software, grounded in a decade of running hospitality operations.
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.
