Software built around your business.
I don't start by picking technologies. I start by understanding how your team works, where time is being lost, and what the software actually needs to accomplish.

Process
From business problem to software your team uses every day.
Good software starts with understanding the workflow — not picking the technology.
- 01
Understand — Map the problem.
We identify how the business works today, where information gets lost, what people repeat manually, and what the software actually needs to solve.
- 02
Scope — Define what matters first.
I turn the requirements into a practical scope, prioritize the highest-value workflows, and establish milestones before development begins.
- 03
Design — Make the workflow understandable.
I design the interface and system structure around the people who will actually use it.
- 04
Build — Develop in milestones.
The product is built incrementally so progress is visible and important decisions can be validated early.
- 05
Launch — Put it to work.
Setting everything up, moving your existing data over, and making sure it runs reliably in daily use are part of the delivery — not an afterthought.
- 06
Support — Keep it running.
After launch, I can continue with maintenance, improvements, bug fixes, and new features as the business evolves.

I'm Trần Quang Khái, a full-stack software developer based in Vietnam.
My work sits between business operations and software development. I enjoy taking workflows that are spread across spreadsheets, chat messages, documents, and manual processes and turning them into systems that people can actually use every day.
Clarity
The software should make a process easier to understand, not add another layer of complexity.
Right-sized solutions
I build what the product actually needs today, with room to grow — never complexity for its own sake.
Ownership
I care about delivering software that the business can maintain, understand, and continue building on.
Real usage
A beautiful interface means little if the team still has to maintain five spreadsheets behind it.

Engagement
Simple engagement. Clear scope.
Every project is different, so I use the scope and complexity of the workflow to determine the final price.
Prices below are starting points — the final quote comes after we agree on scope.
Milestone-based
Projects are split into clearly defined milestones rather than requiring the full project fee upfront.
You own the work
You own the final code and project assets after the agreed handoff and payment terms are completed.
Documented scope
The scope is documented before development begins.
Post-launch warranty
30-day warranty for agreed project defects after launch.
