Understand before building.
I begin by listening, asking questions and defining the problem. A good solution is one people find easy to use.
Vietnam. It starts with curiosity. I like understanding how things work. Over two years, that curiosity has turned into real products: websites, desktop apps and systems running on servers.

Learning by building.
Rust for desktop apps, NestJS for APIs, Docker for deployment. Each project adds a tool that I then put to work on something real.
Ready for what's next.
I take on freelance web and desktop projects: agreeing the scope clearly up front, building from interface to server and improving with every release.
Every journey leaves something behind.Here's what I've built
01 / A little about meD.
One developer,
the whole product.
I'm a freelance Software Engineer with two years of experience, taking on everything from interfaces and APIs to databases and server deployment. Both products below are freelance projects I built end to end for Riviu: a desktop app that controls many phones at once and a brand website that is live today.
Before writing code, I clarify the problem and ask about anything I'm unsure of. Once it's built, I use it myself, write tests for the important flows and fix what still feels awkward.
02 / Selected work
From problem to product.
Software / Multi-device mobile management
Riviu Manager
01
Desktop software for managing multiple Android and iOS devices, with screen monitoring, remote control and workflow automation.
- Tauri 2
- Rust
- React
- TypeScript
- React Flow

The problem
Manage multiple phones, monitor connections and handle repetitive operations without working on each device separately.
My contribution
Built the application with Tauri, Rust and React. Integrated device connections, screen streaming, remote control and device groups, alongside a visual workflow editor and device diagnostics.
Engineering decisions
Separated Android and iOS connections from the React interface, using Rust for device operations and workflow execution. The Flow editor provides visual authoring, while the installer bundles required components to reduce setup on users' computers.
The result
From the device list, users open a phone's screen, control it and run the same workflow across many devices instead of repeating it by hand.
Web / Brand and services website
Riviu Web
Riviu's brand website, presenting media services and pricing with content management and contact enquiries.
- Next.js
- NestJS
- Prisma
- PostgreSQL
- Puck

The problem
Present services and pricing clearly while helping the team update content and monitor the website.
My contribution
Built the Next.js frontend, NestJS API and PostgreSQL database. Implemented a Puck content editor, pricing pages, contact forms and traffic analytics, and deployed the website to a server.
Engineering decisions
Separated the Next.js frontend from the NestJS API for content, enquiries and analytics. PostgreSQL and Prisma store the data; the Puck editor lets the team edit and publish page sections without changing interface code.
The result
The site I deployed for Riviu is live at taskscatt.click, with customer-facing service pages and an administration area for the team.

04 / ExperienceTwo years of
Two years of
shipping software.
Two years of real products taught me that the hard part usually comes after the demo: real data, real devices and real users.
More than getting it to run
I want to understand why code works and where it might break. When something fails, I trace it to the root cause and add a test so it stays fixed.
Talk through concrete examples
A screen, an action or a reproducible bug usually helps people understand each other faster than a long description.
Shipped, not just demoed
From packaging desktop apps to Docker, Nginx and HTTPS, I get products into users' hands instead of stopping at a demo.
