Able to analyse complex scenarios, propose robust solutions and write clean, high-quality code, always following best practices.
I had the opportunity to work with Roni at MRM and I can say, with confidence, that he is one of those professionals who make a difference within a team. [...] I also highlight his ability to analyse complex problems and propose consistent solutions, something extremely important in large projects and e-commerce environments that demand stability, performance and the ability to evolve.
Although he performs exceptionally as a Frontend developer, his experience goes far beyond: he also works as a Backend developer, with a very solid Full Stack vision, and shows excellent ability and architectural vision in building robust, well-structured solutions.
I had the pleasure of working with Roni, an exceptional professional and a great leader, who stands out for his technical knowledge, his strategic vision and, above all, his ability to share knowledge and develop people.
Working with Roni on building and evolving the Marketplace, I found not only an engaged, committed and meticulous professional, but also a trustworthy, motivated and very competent person.
Roni was not just a colleague, he was a mentor for me and thought me everything I know about Magento 2 Frontend. [...] Any team with him becomes better and more efficient, because he's always able to contribute with the tasks and issue, often with very good insights, often taking the responsibility for himself and taking care of the problem.
I had the pleasure of working with Roni for quite some time, at two different companies. I can confidently say that Roni is an exemplary professional. [...] Roni has a keen eye for visual and usability details, which makes a significant difference in the final user experience. Working with him has always been synonymous with trust.

Quick answers
Tap a question. The answer is straight to the point.
Yes. Light landing pages and company websites with semantic HTML, technical SEO and a 99–100 Lighthouse score, like this site. No heavy WordPress, no unnecessary plugins.
I want a landing pageI measure first: Lighthouse, Core Web Vitals and whatever blocks loading. Then I work through the Lighthouse report item by item (LCP, CLS, INP, render blocking, JS/CSS and images) and the backend (SQL queries, PHP, Full Page Cache and Redis). You see the before and after.
I want a faster siteFrom custom modules to architecture: Adobe Commerce Cloud, upgrades, integrations, Luma, Knockout.js and RequireJS frontends. 13+ years of Magento, Adobe Certified Expert Front End.
Talk about my Magento storeBoth. Fixed-scope projects or an ongoing contract for evolution and support, always remote. You talk directly to me, no middlemen.
