About Me

A brief history of time

Daniele Pestilli

Full Stack Developer & System Administrator from Rome

I'm a developer from Italy with an excellent eye for clean, elegant code. I'm a problem solver with years of experience, particularly in backend development. I've worked for an enterprise search technology – Funnelback – in London for more than 3 years, where I served as a support consultant and dev-ops engineer. I then moved to Tokyo to work as a full stack developer for an Airbnb housing management platform at Zens, as a freelance developer at the Milan-based tech house, Mikamai, and am currently a Ruby on Rails developer at Octopi.

I am always very willing to learn new technologies and techniques to add to my already large toolbox of expertise, so that I may always use the right tool for the job. Ruby, Ruby on Rails, Javascript, Coffeescript, Vue.js, jQuery, HTML5, CSS3, SCSS/SASS, Nginx, Git, Solr, Elasticsearch, Ansible, Jenkins are just some of the technologies I am familiar with. I am extremely comfortable with Linux and the command line. I also have the ability to learn new technologies with relative ease. I am a bilingual Italian & English speaker, and can speak business-level Japanese and some Korean. Well versed in Object-Oriented as well as Functional programming principles, I enjoy spending my time playing guitar, drawing, solving difficult problems and writing clean, elegant code.

Technical Skills

I'm quite good at


Ruby on Rails

Ruby enthusiast and Rails aficionado. Very comfortable with MVC development and PostgreSQL is often my database of choice.


System Admin

Proficient with server setups, user creation, package management, bash scripting, log rotation, automated backups, server synchronization, etc.


Search Engine Integration

Familiar with crawlers, faceted & contextual navigation, content indexing, n-gram edit distance, semantic searches and much more.



GNU/Linux geek since age 14. I am familiar with everything from kernel compilation to fstab setup. The command line and Vim are my best friends.



I want my work to consistently be pixel perfect - from internal code to outward design.


Vue.js, jQuery & CoffeeScript

I like to add a bit of dynamics to my web apps, so I tend to make things slide and bounce :)



If something needs to be done more than once, DevOps tools are key. I deploy apps, manage systems and crush complexity.



I've often setup web servers, proxy passes, round-robin load balancing and the like.



Version control has saved my bacon more than once! I use Git religiously.

I was recently tasked with setting up hourly log rotation for a server...
