Whenever I face a challenge I can’t solve on my own or need deeper expertise in the Jmix ecosystem, I turn to Jmix Consultancy Services. Every request has been handled quickly, efficiently, and with great accuracy. The Jmix team is highly professional and demonstrates not only strong knowledge of their own products but also a broad understanding of the wider software and IT industry. As a result, they truly understand my needs and tailor their services to deliver maximum value. My most recent request involved adding complex functionality to a platform add-on, and they not only delivered it seamlessly, but also agreed to include it in future releases, thus saving me from having to maintain it myself.

As a Java backend engineer, I found the JMIX training vital for bridging the gap to UI development. The course’s practical approach and expert instruction boosted my confidence and skills, preparing me to build UIs and transition into a full-stack developer role. I highly recommend this training as a streamlined path to becoming a proficient full-stack engineer without diving into HTML, CSS, or JavaScript.
