I'm Muhammad Junayed, a full stack developer in Dhaka, Bangladesh. I work directly with founders and teams worldwide, from the first call to launch day and beyond.
I started building for the web more than a decade ago and never stopped at one layer of the stack.
Today I design architectures, write the front and back end, ship mobile apps and wire in AI, as one person. That means fewer hand-offs, faster decisions and a single person accountable for the result.
Most clients come to me with a commercial goal rather than a feature list: more bookings, a better checkout, a product that earns before it scales. I build backwards from that number.

Four rules I don't break.
They decide what gets built, what gets cut and how you hear about it.
Revenue first
Every decision is weighed against the number we agreed to move.
One point of contact
You talk to the person writing the code, not an account manager.
Built to hand over
Clean, documented code your team can own after launch.
Honest scope
If something isn't worth building, I'll say so before you pay for it.
Selected engagements.
