Hire the Best C++ Programmers & Developers
in Croatia

Hi I'm Dario, 26 years old programmer and architecture designer from Zagreb, Croatia. Why am I different from others? Well first of all, I am always here, ready to help you bring your ideas to life. You don't need just another coder. You need a technical partner who understands architecture, business logic, and how to ship scalable products fast. With almost a decade of experience building complex systems for high-level clients like the European Commission and various Ministries, I bring "big tech" quality to your project. I specialize in modernizing workflows—combining rock-solid Software Engineering principles with cutting-edge AI Tools to deliver results 10x faster than traditional developers. HOW I CAN HELP YOU: 🤖 AI & Automation Solutions • Building Custom AI Chatbots (RAG) that talk to your specific data. • Python Automation Scripts to replace manual data entry/Excel work. • Integrating OpenAI/Claude APIs into existing apps. 🏗️ Senior Full-Stack Development • Frontend: React.js, Next.js, Vue.js, TypeScript, Tailwind CSS. • Backend: Python (FastAPI, Flask), Node.js, SQL (Postgres/Supabase). • Architecture: Designing scalable MVPs that don't break as you grow. 🔍 QA & Code Audits • Cross-platform testing (Web & Mobile) to ensure bug-free launches. • Codebase Audits: I review your current code to fix performance issues and security risks. WHY WORK WITH ME? • Education: MSc in Software Engineering (FER). • Speed: I use modern "Vibe Coding" workflows (Cursor, AI Agents) for rapid delivery. • Communication: I explain complex tech in plain English. Whether you need a full build, an automation script to save you time, or a consultation to validate your strategy—I am ready to help. Let’s build something future-proof.

With 15 years of professional experience in game development, I specialize in Unity, C#, graphics programming, multiplayer networking, and system architecture. I have a proven track record of leading projects from concept to final release across PC, PlayStation 5, and Xbox Series. My technical expertise includes developing custom rendering pipelines, implementing robust networking solutions, and optimizing performance to deliver immersive and engaging gaming experiences. I thrive in complex, technically challenging environments and am passionate about crafting high-quality interactive experiences. Let’s collaborate and bring your project to life!

I’ve been in game development since 2015, starting as a Unity programmer and expanding into 3D modelling, environment art, and Unreal Engine production over the years. I’ve worked on mobile titles, VR/AR museum experiences, and larger commercial projects—including: Relevant Experience ✔ Lead Programmer & Technical Designer — “Go Home Annie” Demo (Steam Release) I was the sole programmer on this horror title during its Demo phase and collaborated closely with the creator on 3D modelling, environmental design, gameplay systems, and optimization. This project reflects my ability to own an entire technical stack, ensure code quality, and translate vision into a functional product. ✔ AR Developer — “The Silence that Tore Down the Monument” (Europa Nostra Award Winner) I developed the full AR experience. Over the last year, I’ve been deeply exploring UEFN, Verse, systems scripting, UEFN databases, and Creative ecosystem constraints. I’ve built several unpublished prototypes—some small mechanic tests, some larger systems—and released one Halloween-themed map to understand publishing, memory limits, and discovery workflows. My background in Unity scripting and Unreal Blueprint concepts made Verse a natural extension, and I’m now comfortable building: Gameplay systems and interactive logic Data-driven mechanics using UEFN databases Modular and scalable systems designed for iteration Levels that balance gameplay readability, pacing, and performance

Hey there, I’m Mateo! I build things that exist in two places at once: in code, and in the physical world. My expertise spans over multiple scientific and engineering fields, so I'll try to summarise everything properly. On the software side, I program in Unity's C#, as well as Python, C & C++. Gameplay systems, simulations, interactive tools, and technical visualizations. On the hardware side, I design and fabricate working physical systems: custom electronics a chemical reactor, Arduino based control loops, sensor integration, and CAD-modeled mechanical parts. But my strongest project bridges both. You see, I designed and built a working Birkeland-Eyde chemical plasma reactor from scratch (custom electronics, Arduino PID control, and a full chemical scrubbing system), which won Gold and a Trophy at INOVA-MLADI 2026. What I can build for you, specifically: — Unity gameplay systems, prototypes, and interactive simulations, — Custom C# tools, editor extensions, and technical visualizations, — Arduino/embedded hardware projects (sensors, control loops, automation), — CAD modeling and technical design (Fusion 360), — Projects that need both; software-controlled physical systems, instrumented prototypes, sensor-driven simulations. I move fast, communicate clearly, and care about a working result more than a polished pitch. If your project needs someone who can take a rough machine-level concept all the way to something real then look no further. If you have any additional questions please feel free to contact me!


I have spent hundreds of hours on mobile game and app development. I’m in the IT industry since I was a kid, and have recently co-founded my own game development studio - quasiStudio - you can check it out in my portfolio! I am a developer with over 12 years of official experience with software development, and 5 years of game development. Most recent work of mine is the Android app for Croatia’s largest classified ad website called Njuskalo, which I have worked on for more than 3 years. My latest success is developing a photo recognition feature that recognizes objects on the photos, where AI analyses the photo and matches them with their belonging categories. If the AI has chosen the wrong category, the user can easily improve the AI by presenting the correct category while making the AI better and smarter. When it comes to games, my partner and I have just released the first game under our studio’s name called AeroAttack. It’s a simple 2D space-shooter game with all the necessary implementations, you can check it out in my portfolio! I have experience working alone and in teams, I know how to communicate with any members of a development team. I have used a wide range of version control and ticket tracking software, and therefore I know how to structure goals to meet deadlines. I am consistent and very effective when it comes to my work, and I have the necessary skills for the job. You communicate what you want, I will create it in no time, and make sure we’re both satisfied in the end! Listed below are my technical skills. — Programming languages: C/C++, Java, JavaScript, C#, Kotlin; — Java libraries: Slick2d, LWJGL, Retrofit, RxJava, RxAndroid, ButterKnife, and others; — Data/Markup: XML, XML Schema, JSON, HTML/CSS; — IDE: Visual Studio, Eclipse, Intellij Idea, Android Studio; — Asset Creation Software: Blender, Maya, 3dsMax; — Texturing Software: Photoshop, dDo, nDo, 3Do, MegaScans; — OS: Android, Linux, Windows, Mac OS X; — VCS: Git, SVN, CVS, Perforce; — Engines: Unity, CryEngine, UDK, Unreal Engine 4, Cocos2d-x; — Collaboration tools: Trello, Taiga.io, JIRA, Toggl; — Utility: Makefile

My top skills are Gatsby, React, Node.js, Django, Vue, Quasar, React Native, and AWS. Worked on multiple web projects where my role was full-stack developer and quite often I would take the role of DevOps if needed. I am also experienced with Construct 3, Godot, and GMS. I started my career as a game developer, but I always wanted to learn more so my next stop was Web and mobile development. ⭐️ Experience in Web development as: ✅ Front-end developer(jamstack) ✅ Back-end developer ✅ Full-stack developer ✅ DevOps ⭐️ Experience in game development as: ✅ lead programmer ✅ designer ✅ pixel artist
