Founder & CEO
Khalid Saifullah
Engineer-founder building the AI-native eCommerce platform for Bangladesh's 2,400+ SeloraX merchants.
"I'm a software engineer turned entrepreneur. The best technology is the kind that solves a real problem for a real business — for Bangladeshi merchants, that means one dashboard that sells, ships and shows profit."
Biography
Khalid Saifullah is the Founder & CEO of SeloraX, the AI-native eCommerce platform built for Bangladesh and the technology company of Smart Capital PLC. A full-stack JavaScript engineer with more than seven years of experience across React, Next.js, Node.js and React Native, he has spent his career turning manual business workflows into software — first for clients, then for his own ventures, and now for thousands of Bangladeshi merchants. Before SeloraX, Khalid founded KS Devware in 2021, a software studio building revenue-generating web and mobile applications, and WorksLee in 2022, a peer-to-peer marketplace for local service workers. He co-founded the eCommerce brands Adatun and Arrtal as Chief Technology Officer, led the Bangladesh engineering team at NōME, a social art marketplace built on Bitcoin, and worked as a senior frontend engineer and UI/UX designer at Health Hero, a US health-technology company. He has also trained more than 500 students as a programming instructor. Running online brands in Bangladesh showed him the gap first-hand: orders on Facebook, inventory in spreadsheets, bKash and Nagad statements, courier portals, phone calls to confirm cash-on-delivery orders, and no clear view of real profit. SeloraX is the single dashboard he wished existed — an AI agent that sells on Messenger and WhatsApp, an AI call that confirms every COD order in Bangla, fraud caught before shipping, couriers one click away, and accounting that shows profit, not just revenue.
