Freelance Senior Full-Stack Engineer with 12 years of Ruby on Rails

As a Senior Full-Stack Engineer specialised in Ruby on Rails I cover everything from the server to the interface: backend, cloud infrastructure, frontend, accessibility and UX. Today, with the help of AI, I can take on virtually any task in the software production chain.

Let's talk about your project

Background

From code to cloud, end to end

I started with Ruby 12 years ago and, right from the start, I also took on the cloud infrastructure of the applications I worked on: servers, deployments, databases and monitoring. Sometimes I ran it entirely on my own, other times together with the institutions' own teams.

My core strength is the backend, but I never stopped there: I've taken on all kinds of frontend, accessibility (a11y), UX, analysis and estimation work, always using agile methodologies.

That experience gives me a complete view of the product: I understand how every technical decision affects the people who use the application and the people who maintain it.

What I bring to your project

One single profile who understands every layer of your application.

Solid backend

My core strength. Business logic, APIs, databases and integrations with Ruby, built to grow and stay easy to maintain.

Cloud infrastructure

Servers, deployments, backups and monitoring of production applications, on my own or alongside your team.

Frontend

Clear, functional interfaces, well connected to the backend behind them.

Accessibility and UX

Applications anyone can use, with care for accessibility (a11y) and user experience.

Analysis and estimates

I turn needs into clear requirements and realistic estimates before writing a single line of code.

Agile methodologies

Small, frequent deliveries, clear priorities and constant communication with your team.

How I work

Proactive, pragmatic and fast

Right now, with very powerful AI models at hand, I always try to be pragmatic and build the minimum version of what my clients need. These days it's easier to overdo it than to fall short.

I don't wait for a client to report a problem: if I see an exception or find a bug myself, I investigate and fix it, sometimes before it affects anyone.

I respond fast, with solutions. When a client needs me, I put all my energy into giving them a concrete answer with a solution as soon as possible. It's one of the parts of my work I enjoy most: surprising my clients with professionalism and unbeatable response times.

With the help of AI

The whole production chain, one single contact

  • Analysis

    I understand what you need and why, and turn it into clear requirements.

  • Estimates and planning

    Realistic estimates and an iterative plan to move forward with clear priorities.

  • Backend and frontend development

    AI speeds up the repetitive parts; I review every change myself, backed by tests and delivered in small steps.

  • Quality, accessibility and UX

    Testing, accessibility review and care for the user experience before every release.

  • Deployment and infrastructure

    Going live in the cloud, with servers and deployments under control.

  • Monitoring and support

    I keep an eye on the application in production and respond quickly when something comes up.
