La mia storia

Daniele Pestilli

Sviluppatore Full Stack & sys-admin da Roma

Sono uno sviluppatore italiano che presta particolare cura ed attenzione nello scrivere codice pulito ed elegante. Ho anni d'esperienza nel risolvere problemi complessi, in particolare nello sviluppo back-end di applicazioni web. Ho lavorato a Londra per più di 3 anni presso la Funnelback, una tecnologia di ricerca, come consulente di supporto e ingegnere DevOps. Mi sono successivamente trasferito a Tokyo per lavorare come sviluppatore full-stack per una piattaforma di gestione di alloggi Airbnb presso la Zens, e poi come sviluppatore freelance presso l'azienda tech Milanese, Mikamai. Sono attualmente uno sviluppatore Ruby on Rails presso la Octopi.

Sono sempre molto desideroso d'apprendere nuove tecnologie e tecniche da aggiungere alla mia gamma di strumenti, in modo da poter sempre utilizzare la tecnologia adeguata per il lavoro richiesto. Ruby, Ruby on Rails, Javascript, Coffeescript, Vue.js, jQuery, HTML5, CSS3, SCSS / SASS, Nginx, Git, Solr, Elasticsearch, Ansible, Jenkins sono solo alcune delle tecnologie con quali sento di poter offrire risultati ottimi per problemi difficili. Sono estremamente a mio agio con Linux e la riga di comando. Ho anche la capacità di apprendere nuove tecnologie con relativa facilità. Sono bilingue italiano ed inglese e parlo sufficentemente il giapponese da poterlo utilizzare in un ambiente lavorativo. Sono ben informato riguardo entrambi i principi di programmazione funzionale e ad oggetti. Mi piace trascorrere il mio tempo suonando la chitarra, disegnando, e risolvendo problemi di computazione scrivendo codice pulito ed elegante.

Abilità Tecniche

Me la cavo con...


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.
