Much of our work is delivered as a white-label technical partner for agencies or on projects where confidentiality matters. For this reason, not every organisation we support can appear in our public portfolio.
We provide long-term maintenance, custom WordPress development, WooCommerce solutions and technical problem solving for businesses, agencies and research organisations.
If you are considering working with OptArt, contact us. Where appropriate, we can provide relevant references or introduce you to selected clients who can share their experience of working with us.
Research institute experience
We support the Leibniz Institute for New Materials (INM) with WordPress development and ongoing technical work.
“I was working with Marcin and his team couple of times with great results! Fantastic communication and management skills were very helpful and let us finish our projects with success! Will be cooperating in future for sure.”
Michal Fraczek
COO @3di Poland
“Marcin and his team have provided web development for several projects, and in addition has provided strategic input and recommendations. He is very professional – he sets realistic expectations for timely, high quality deliverables, and is willing to adjust mid-project when needs require it.
Trevor Tunnacliffe
Principal at CurrentDesign
“Responsible, reliable, good time keeping and easy to get along with. All of his work was done to the highest standard. Marcin is a pleasure to work with!”
