I am a Software Engineer and I work as Head of Technology at Black Studio, a web agency specialized in WordPress development, design and hosting.


Our team includes engineers, developers, designers, SEO specialists, content architects so we’re able to take care of complex projects that require a wide range of skills.


We have over 18 years of experience in website development, and we work almost exclusively on WordPress projects since 2010. We’ve built more than 300 WordPress websites over the years, also providing and managing hosting and ongoing support.

We’ve specialized in advanced customizations of the backend and frontend of WordPress, and integrations with 3rd party services. I extensively work with OnTheGoSystems products like Toolset plugins and WPML, and I’m also in their consultants list with my agency. We’re often involved in bug reporting and fixing, and in making improvements that they adopted in the following releases.

We extensively use Genesis Theme Framework for most of our projects, either customizing existing child themes or building them from scratch. We do also have experience with WooCommerce solutions and related plugins. We do have a wide knowledge of existing free and commercial plugins, so for every WordPress problem, we’re able to find a solution either based on existing plugins, or develop it from scratch when no other solution is available, or sometimes use a mix of the two approaches.

Often we take care of different kinds of tasks on existing sites, i.e. Speed Optimization, Security / Hardening, Data migration/conversion, etc.

We developed some free WordPress plugins that are available on the official WordPress plugin repository. The most popular is Black Studio TinyMCE Widget, which is in the list of the top 30 popular plugins on wordpress.org, and it is often included in blog articles listing the best or more popular plugins (i.e. GoDaddy’s top 100). It counts more than 9.000.000 downloads with a 4.8/5 average rating.
This plugin is a good representation of the way we work: it’s simple, clean, solve straightforwardly and cleverly a common problem, and it’s loved by the users.

We are active members of the WordPress community, as WordCamp speakers, Meetup/WordCamp organizers, Polyglots and Core Contributors

We work on Codeable since 2015.

Our web site was running slower than a turtle, thanks to bloated code and some issues that had gradually developed over time. Marco came in and whipped the code into shape, and restored the performance we had been missing! When the others developers who bid on our project all said “you’re in good hands with Marco,” that’s the highest compliment one could give.
