An engineer who believes in the power of education.

Pupils today are often left to their own devices when it comes to using AI, so through IRIM I launched a league in which they use it openly, with the goal of every team building its own app. I wrote the curriculum, led the league and sat on the jury.

We planned for 50 schools, and in the end 155 schools and 230 teachers worked in the league. Of the 217 entries submitted, ten made it to the final.

The league was supported by the Ministry of Science, Education and Youth, EDIH CROBOHUB++ and Telemach.

The Croatian Makers movement, and above all the League as its first project, brings together three things a school struggles to solve on its own: equipment, mentor training and a competition that gives a reason to work all year round. Through IRIM I led the league from 2016 to 2025.

The league grew to 600 schools in Croatia, working with the mBot and Maqueen educational robots.

It was later also run in Serbia, Bosnia and Herzegovina, Kosovo and Montenegro, with donated equipment and training for local mentors.

We recognised the potential of AI early, and as far back as 2023 we brought it into schools through hands-on work, building on the Croatian Makers League. We donated 600 AI cameras to schools, developed a curriculum and teaching materials, trained and mentored teachers and organised competitions for pupils.

Our partner was The European Wergeland Centre from Oslo, and the project closed with a conference in Crikvenica in September 2023.

The project reached more than 300 schools, and it also gave rise to the handbook Umjetna inteligencija u STEM edukaciji (AI in STEM education), which I edited with Maja Mačinko.

Digital Citizen grew out of the STEM Revolution in libraries. It was a regional digital literacy programme in libraries in Croatia, Serbia, Bosnia and Herzegovina and Kosovo, funded by Google.org.

Libraries received micro:bits, BOSON experiment kits and 3D printers, which members of the public can use and borrow openly and free of charge, and librarians received training to run workshops.

In the first phase 176 libraries were equipped, and there were 83 workshops for librarians and 1,512 free workshops for the public, with 13,105 participants and 20,059 equipment loans. I was the STEM education expert and led the follow up, Digital Citizen 2.0.

The STEM Revolution began in 2017 with a Croatian Makers crowdfunding campaign for micro:bits in schools, and over time the micro:bit reached around 1,000 educational institutions. It continued with the ProMikro programme, in which sixth graders in 85% of primary schools in Croatia received a micro:bit.

In 2018 the STEM Revolution in libraries brought more than 3,000 micro:bits to more than 110 libraries, and Digital Citizen grew out of it.

With the Rotary Club Zagreb Centar and Rotary District 1913, the STEM Revolution also reached the lower primary classroom, from first to fourth grade. In 2019 the pilot covered 58 schools in Vukovar-Srijem, Virovitica-Podravina and Osijek-Baranja counties.

I co-authored Svijet tehnike (The World of Technology), the technology education textbooks for grades 7 and 8 of primary school, and the working materials for both grades.

Svijet tehnike 7 was also published in Italian and in Hungarian, with the same authors.

• Svijet tehnike 7, textbook, Školska knjiga, 2020
• Svijet tehnike 7, working materials, Školska knjiga, 2020
• Svijet tehnike 8, textbook, Školska knjiga, 2021
• Svijet tehnike 8, working materials, Školska knjiga, 2021
• Il mondo della tecnica 7, Edit, Rijeka, 2022
• A technika világa 7, Educational and Cultural Centre of Hungarians in Croatia, Osijek, 2023

Praktične vještine (practical skills) builds the basic knowledge, skills and fine motor control that almost every lower primary pupil lacks today. The series covers timeless topics, from housekeeping, creative projects and road safety to small repairs, sewing and healthy eating.

Each grade gets a kit for 35 hours of lessons, with step by step picture instructions and all the tools, equipment and materials, and teachers get a handbook and an annual teaching plan. Every grade also has a board game on financial literacy.

I have been developing the series for Školska knjiga since 2023, and for now it is being run experimentally, within the full day school project.

• Praktične vještine 1, 23 exercises and the game Učim o novcu (Learning about money)
• Praktične vještine 2, 20 exercises and the game Ja, poduzetnik! (Me, an entrepreneur!)
• Praktične vještine 3, 19 exercises and the game Mjesečni budžet (Monthly budget)
• Praktične vještine 4, 19 exercises and a game about saving and investing

For Školska knjiga I edited the whole series of textbooks for the first year of vocational secondary schools. The four textbooks come with four workbooks, and every title has digital content on the e-sfera platform. On the Osnove elektrotehnike (Fundamentals of electrical engineering) workbook I am also credited as co-author with Saša Tatar.

• Tehničko crtanje i dokumentiranje (technical drawing and documentation), Danijel Eskeričić and Mario Tretinjak
• Osnove elektrotehnike (fundamentals of electrical engineering), Saša Tatar
• Uvod u računalne mreže (introduction to computer networks), Renato Matejaš
• Osnove strojarstva (fundamentals of mechanical engineering), Mato Galović

Arduino kroz jednostavne primjere (Arduino through simple examples) is the first book about the Arduino platform in Croatian, and also my first published book. I am its sole author, and it was published by the Croatian Technical Culture Association.

On Google Scholar it is my most cited title, ahead of all my scientific papers. A new edition is coming soon.

• 1st edition, 2014
• 2nd edition, 2016

I wrote the series of four handbooks for teachers through IRIM and finished it in February 2026.

• Razumijevanje umjetne inteligencije: osnove, povijest i slojevi AI-a (understanding AI, its basics, history and layers)
• Umjetna inteligencija u nastavnom procesu: kontekst, prompting i meta prompting (AI in teaching, context, prompting and meta prompting)
• Učenje s umjetnom inteligencijom: od pasivnog korištenja do aktivnog učenja (learning with AI, from passive use to active learning)
• Umjetna inteligencija i pristupačnost: konkretni alati za inkluzivno obrazovanje (AI and accessibility, practical tools for inclusive education)

With Hrvoje Vrhovski I wrote three handbooks for teachers for the Technical Culture Association of the City of Osijek, covering the equipment that schools and associations create with today, from the laser cutter to the 3D printer. They are available on Edutorij.

• 2D stvaralaštvo kroz lasersko rezanje: priručnik za laserski rezač Falcon Pro (2D creation through laser cutting, a handbook for the Falcon Pro laser cutter)
• 3D stvaralaštvo: trodimenzionalni tisak i modeliranje, uz Bambu Lab pisač i Tinkercad (3D creation, printing and modelling with a Bambu Lab printer and Tinkercad)
• 2D stvaralaštvo: tisak i dizajn, uz Cricut Explore 4 i EasyPress 3 (2D creation, printing and design with Cricut Explore 4 and EasyPress 3)

As author I am credited with 55 digital learning materials in electrical engineering and 16 in mechanical engineering, and as co-editor I worked on 192 materials in electrical engineering and 204 in mechanical engineering and shipbuilding.

Fifty of them are publicly available in the FreeDOM repository, among them the EASA PART-66 modules.

I wrote the handbook with Ana Tolić and Dorian Tepić, and IRIM published it in 2020. The same year it also came out in Italian, as Nozioni di creatività digitale con micro:bit.

AI4T is an Erasmus+ project run by a consortium of five organisations from Croatia, Romania and Greece, led by Ivan Cankar Primary School. The project idea is mine, and I led the project.

The outcome is the ai4teachers.app platform, with 33 lessons and 33 videos.

In the Croatian Makers League, mentor training always went hand in hand with the equipment, and we took the same model, with training for local mentors, to Serbia, Bosnia and Herzegovina, Kosovo and Montenegro.

Digital Citizen held 83 workshops for librarians and trained 368 librarians. In the STEM in the Community project we trained teachers and mentors and took mobile robotics workshops by STEM car to rural areas and smaller communities.

For Soldered Electronics I lead content development and advise on how to apply AI technology to content creation and business process automation, with a human in the loop approach, in which a person always has the final word.

I led the move to PIM managed content and to solde.red, the new product data site, which went live on 17 July 2026, and as an expert I oversaw the building of the Soldered Docs 2.0 documentation platform.

For a single ministry call in 2025 alone, I wrote applications for at least 12 organisations.
