Vo Ky Truong · Full-Stack TypeScript Developer

From fog
to product.

I design, code, and ship complete web applications - from the scoped idea all the way to deployment, with nothing handed off along the way. Available freelance or full-time, fully remote or hybrid in the Paris region.

  • 3 SaaS under construction
  • 10 years in software
  • MSc-level engineering degree
  • TOEIC 945/990
Developer role: code, architecture, deployment, Git branches, and AI

An app to build, a team to strengthen.

A product to build, a mission to staff, or a team to strengthen: that's my job. I build from scoping to launch. One person to talk to, the one who writes the code.

One point of contact

You talk to the developer, not a project manager.

Shipped live

I don't stop at the prototype.

Full-stack, solo

Front, back, data, payments, AI. Nothing outsourced.

Products I've shipped.

Three products live. I designed them, coded them, and I run them myself: front, back, payments, AI. Not mockups. Real, under construction.

How it works.

  1. 1

    First conversation

    Your need or your job spec. If I'm not the right fit, I'll say so.

  2. 2

    Scoping

    Scope, priorities, budget, clear before the first line of code.

  3. 3

    Development

    You see it move forward, delivery after delivery.

  4. 4

    Live

    Deployed, operated, maintained.

The full stack.

The detail, for anyone who wants to look under the hood. What matters is above: the products shipped.
