Hire a freelance full stack developer

Hiring a full stack developer means one person can own your product end to end: the database, the API, the interface, and the deployment. No coordination overhead, no waiting on another team, no gaps between layers where bugs like to live.

I have been doing exactly that for over ten years, mostly for early stage startups. My stack is TypeScript, Node.js, React, and PostgreSQL, deployed on AWS, Google Cloud, or Cloudflare depending on the project.

What makes Ruan stand out is that he actually cares about the work he does. He wants each line of code to be his best work.

Not in a I'll-take-my-own-sweet-time kind of way. But in a I-want-to-help-the-business-succeed kind of way.

What I can help with

  • Complete web applications, from database schema to polished UI
  • Backend: Node.js APIs, PostgreSQL, queues, and integrations
  • Frontend: React with TypeScript, design systems, responsive UI
  • Infrastructure: Docker, Terraform, CI/CD, and cloud deployment
  • User interface design when there is no designer on the team
  • Ongoing product development on a monthly retainer

Experience

As founding engineer at VESYL I built the entire product across the stack for close to five years: backend, frontend, integrations, and infrastructure. I built the streaming backend for Barry’s Bootcamp, worked on a platform with over a million users at Testlio, and shipped complete products for Queie, Flipfox, and Frevo.

Questions

What is your stack?

TypeScript everywhere, Node.js on the backend, React on the frontend, and PostgreSQL for data. For infrastructure I use Docker and Terraform, deploying to AWS, Google Cloud, or Cloudflare. I am pragmatic about it: if your existing stack is different, I adapt.

Do you work alone or with a team?

I work solo, so the person you email is the person writing the code. For larger projects I can bring in people I trust, but I stay hands on either way.

How long does a typical project take?

It varies with scope. A focused MVP is usually measured in weeks, a larger build in a few months. When I send a proposal it includes a realistic timeline, and I keep you updated as the work progresses.

How much does a freelance full stack developer cost?

I price by project or by monthly retainer, not by the hour, so the cost is clear before we start. Scope drives the number. Email [email protected] with what you are building and I will put together a proposal.
