A brief history of time
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'm quite good at
Ruby enthusiast and Rails aficionado. Very comfortable with MVC development and PostgreSQL is often my database of choice.
Proficient with server setups, user creation, package management, bash scripting, log rotation, automated backups, server synchronization, etc.
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.
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.

Always challenging myself to learn
Deep learning is driving advances in artificial intelligence that are changing our world. The course covered Convolutional and Recurrent Neural Networks, Generative Adversarial Networks, model deployment and more using PyTorch. The course instructors include: Sebastian Thrun, Ian Goodfellow, Jun-Yan Zhu, and Andrew Trask.
This course teaches the foundations of AI with Sebastian Thrun, Peter Norvig, and Thad Starner. It covers Game-Playing, Search, Optimization, Probabilistic AIs, and Hidden Markov Models. Projects include a Sudoku solver, a Pacman game that uses search to travel through a maze, a planning agent to determine air cargo transport systems and a word recognizer for American Sign Language video sequences, using probabilistic models.
The course covers algorithmic techniques and ideas for computational problems arising frequently in practical applications: sorting and searching, divide and conquer, greedy algorithms and dynamic programming. This course also covers how sorting data helps for searching; how to break a large problem into smaller pieces and solve them recursively; when it makes sense to proceed greedily and how dynamic programming is used in genomic studies.
This course covers search engine technologies, which play an important role in data mining nowadays. It investigates how search engines and recommender systems work. Concepts such as stemming, 'bag of words', probability ranking, Vector Space Model, Term Frequency (TF), Inverse Document Frequency (IDF), pivoted length normalization, BM25, Unigram Language Model, Rocchio algorithm, PageRank, HITS, and many other concepts (along with their benefits and weaknesses) are discussed.
In this course students learn programming in R, reading data into R, creating data graphics, accessing and installing R packages, writing R functions, debugging and organizing R code.
This course investigates the basic concepts behind programming languages, with a strong emphasis on the techniques and benefits of functional programming along with many other topics, such as modularity and the complementary benefits of static and dynamic typing. Languages used in this course include SML (functional programming), Racket (multi-paradigm) and Ruby (object oriented).
A collection of my thoughts
Deep Learning has taken the world by storm in recent years. Whereas computer algorithms were already able to beat the leading world chess players in the late ‘80s, the most famous success story being the victory of Deep Blue over then World Chess Champion Garry Kasparov in 1997, other games...
Logs are an important part of any web application. Too few logs make debugging issues a problem. On the flip-side, too many logs can make a disk max out of space, or finding a specific error harder than it should be.

If one wished to find a book in a library before the digital age, one would seek a librarian and request the book either by title or by author. The librarian would then go through stacks of books and retrieve the desired text. If one knew that the library organized its books by ISBN, one might...
Dokdo is an island comprised of two islets, Dongdo (East islet) and Seodo (West islet). This small plot of land is located in the East Sea and is almost equidistant from Japan and Korea. Several other names have been ascribed to Dokdo as foreign countries encountered these rocks: in 1849, the...
