Descripción

Hi, I'm Francesco, an experienced software engineer passionate about building simple solutions that deliver high impact and drive business growth.

My portfolio includes a wide range of applications, having worked on API integrations, data collection, performance optimization, and dashboard applications. Mostly worked on the Backend applications, but also contributed to Frontend apps (React and Vue.js)

Here are some of my accomplishments:

  • Refactored endpoints to simplify the APIs consumption for the Frontend app
  • Implemented a request queue with a retry mechanism for the Javascript app we serve to our DSPs to improve data consistency
  • Implemented a new automation that increased our CSV export speed by 600%
  • Contributed to a DSP integration that reduced publisher costs by 35%
  • Contributed to scaling our Notification system by 400%, increasing revenues by 7%
  • Developed a Ruby gem that reduced our error-monitoring service costs by 25%

I'm particularly interested in Backend and Full-stack positions where I can apply my expertise with Ruby, Rails, Javascript, Rspec, MySQL, PostgreSQL, Redis, and Queue systems. I'm also familiar with React, Vue.js, Hotwire, Docker, Kubernetes, and the AWS ecosystem.

In addition to my technical skills, I am a collaborative team player with good communication skills. I can work cross-teams and with different stakeholders, but I can also work solo when required. I have a strong sense of ownership over the systems I work on, and I'm always eager to expand my skills and develop myself, technically and personally.

I'm a very curious person and I like working on side projects in my spare time and exploring new technologies. I also enjoy 3D modeling, tinkering with electronics, and engaging in DIY activities.
