I’m Nicolò, a husband, Software and Cyber Security consultant, vegetable grower, part time archer and vintage lens collector.
I’m currently working fully remote as a Senior Software Engineer and Team Lead for an italian company in the eCommerce space where I deal with complex problems in designing and developing distributed and resilient systems, with high throughput, resiliency and security in mind. I do that employing an Object Oriented Pogramming language such as Ruby. Tech stacks I’m mostly working right now comprise Ruby, Rails, Stimulus, Heroku, AWS (Lambda, RDS, SQS and ECS).
In my spare time I like to grow my Cyber Security skills by participating in Bug Bounty programs.
I also run a YouTube channel (in Italian 🇮🇹) where I talk about Cyber Security, Coding (specifically Ruby), and Artificial Intelligence. My goal is to share what I learn and make technical concepts accessible. Check out the channel.
Past experiences include (recent to less recent):
