  My partner and I teamed up with Silvestar this year to bring our new company’s website to life, based on some design sketches I had. The work he did for us was top-notch. Throughout the process, we felt in good hands with his expertise and his readiness to go the extra mile to guide us through the different steps.

  It’s worth mentioning that he was super quick in getting the job done and was really accommodating with our requests. The whole experience was smooth and enjoyable. We’re looking forward to the next chance to work with him!

  We've worked with Silvestar on several projects, and he's been a pleasure to work with on all of them. Recently, he handled primary front end development for two large web sites that were launched on Adobe Experience Manager. He's also worked on the front end development of a large WordPress project as well as some smaller campaign landing page and microsite work.

  In all cases, Silvestar's been a breeze to work with. Communication is easy, and he's happy to be part of a larger team, attend regular standups, stay in close communication electronically, etc. (a key factor when working across countries/time zones).

  His approach to front end development is modern, but he still knows how to debug for Internet Explorer and handle browser-specific issues. He's a thorough tester and has a great eye for detail.

  Additionally, he's very fast. We were always impressed with the speed at which he could put things together at a very high level of quality.

  I'd happily work with Silvestar again, and we'll definitely reach out to him in the future when we need help with additional projects.

  I recently worked with Silvestar on a webpage development project. He was extremely professional, capable, responsive, and very pleasant to work with. He managed numerous design revisions and small detailed feedback (sometimes multiple times per day) with ease and with fast turnaround. He was also very honest and reasonable about the level of effort required to complete the project from the very first meeting. I would absolutely work with Silvestar again and wish him much success on his future endeavors!

  It has been a pleasure working with Silvestar on various web development projects. He is not only technically skilled at his job, I am also continuously impressed with how proactive he approaches his work. In addition to finding and responding to issues, he is always looking for ways to optimise and make changes on his own. On top of his skillset, he is excellent at explaining what he is doing in a straightforward way, is always ready to help when needed and easy to work with. I can strongly recommend working with him!

  I worked with Silvestar for when I first started at Domino Data Lab, he was instrumental in some of my first big wins as Head of Partner Marketing, including launching the Domino Partner Network - a massive milestone for us!

  Silvestar is detail-oriented, extremely responsive, and very creative with bringing solutions to work around dependencies and constraints. I have no doubts that Silvestar will be a key resource for any organization he joins!
