Full-stack developer · Taking on new projects

I design and build the software businesses run on.

I'm Martin Fernandez, a full-stack developer with five years of experience. I've designed, built and launched platforms for clinics, labs, law firms and invoicing that thousands of people use every day. I lead each project end to end, from the data model to the last screen.

/approach

How I work

  1. 01

    Understand the work

    I start by learning how your team works today and which tasks take the most time. The software follows from that.

  2. 02

    Ship in small pieces

    You see working software early and often, so we can adjust before anything gets expensive.

  3. 03

    Keep it running

    After launch I stay close: fixes, improvements and new features as the business grows.

On AI

AI is part of my daily workflow. I follow the industry closely and see it as a tool that lets small teams build faster and better, and I integrate it into products where it makes a real difference for the people using them.
