Open to a small number of thoughtful collaborations

Independent product builder VI / EN / JA / ZH

I turn messy operations into software people can run and keep improving.

From product framing and architecture to full-stack delivery, I build tools that make the next operational decision easier.

A working belief

I do not build features to fill a list. I build systems that make the work run better.

At a glance

Good products start with a well-understood operating loop.

LogiVN

LogiVN connects QR menus, modifiers, combos, orders, kitchen, tables, reservations, payments, stock and staff operations in one workspace for Vietnamese cafes and restaurants.

Make the next decision obvious; hide complexity that does not help.

Selected work

Products built around the work people actually do.

Each project starts with a specific coordination problem, then grows into a system that can be run, checked and changed.

From operations to product

Do not start with screens. Start with the state that needs to become clear.

I look at how information, responsibility and decisions move through a working day, then turn the highest-leverage loop into a workflow people can trust.

  1. 01Understand the loopObserve the real work and find where decisions are slowing down.
  2. 02Name the stateTurn scattered signals into a state the whole team can understand.
  3. 03Design the boundaryClarify data, permissions and ownership before expanding the interface.
  4. 04Build and verifyComplete one operating loop, verify it in context, then expand.

How I think

Technology earns its place when the way of working gets better.
  1. 01Complex inside, clear outside.
  2. 02Keep data and permission boundaries explicit.
  3. 03Expand when the foundation has earned it.

Bring the concrete problem: a repeated handoff, a disconnected system or a product that needs a stronger foundation.
