I build software & AI products — and ship them.
I'm Nayem Hossain, a hands-on builder from Bangladesh and Founder & Chairman of NCTTI. Web apps, Android apps, AI chatbots and automation — from idea to a live product people can actually use.
A builder who learns
by shipping real things.
I don't wait for perfect conditions. I prototype fast, test on a real phone, listen to real users, and iterate. That approach has produced education apps, music platforms, payment tools, AI workspaces, VPN apps, e-commerce stores and business automation — most of them live and in daily use.
বাংলাদেশের ডিজিটাল ভবিষ্যৎ গড়ি — এটা NCTTI-র tagline, আর আমার কাজের মূল কথা।

How I got here
Finished SSC (GPA 3.67) and kept building — Termux, Linux on Android, and first real projects on a phone.
Bangla, English, ICT, Economics, Civics & Agriculture — alongside shipping apps, bots, stores and AI tools one after another.
Nexus Creative Technology & Trade Innovations — a Dhaka-based, remote-first software & AI services company, bootstrapped from ৳0 with an 11-member AI workforce.
30+ products shipped: education, music, payments, AI agents and business automation. Next: first clients, break-even, and ShebaBot — a Bangla AI support chatbot SaaS.
