with a point of view.
I’m Dario Carić, an independent developer. I started developing for iOS in 2010 and have spent more than 25 years working with software, including over seven years of dedicated full-stack development with modern JavaScript and React.

My iOS journey
Building for iPhone since 2010.
What began as a hobby became a long-running creative practice. Since 2010 I have independently developed iOS applications for iPhone and iPad, from location-aware utilities and public transport tools to AI-powered games, augmented-reality experiments, weather apps, and practical business software.
Each project is an opportunity to connect real-world functionality with a polished user experience and to explore a different part of Apple’s platform.
Selected projects

Each project is an experiment in making a specific kind of information, action, or story easier to access.

Making AI useful after the demo.
After the major breakthroughs in generative AI and LLMs in 2022, I began actively implementing large language models and working with AI in practical software projects. I build domain-specific, production-ready chatbots using both open-source and proprietary models. The focus is not only on generating text, but on grounding answers in facts and connecting them to real actions.
My work includes fine-tuning Gemma models with Parameter-Efficient Fine-Tuning and LoRA, multilingual Retrieval-Augmented Generation using SentenceTransformers and FAISS, and FastAPI backends that support self-hosted and API-based inference.
I have tested locally hosted Gemma variants alongside API-based systems such as Google Gemini, balancing cost, speed, and accuracy. These systems power a booking assistant for Apartments-Hvar.com, a technical chatbot for this portfolio, and the local Gemma Council.
The booking assistant combines retrieval with deterministic logic for multilingual intent detection, date understanding, email validation, reCAPTCHA security, booking availability, and automated confirmation emails to both guests and owners.

A local-first operations desk for apartment owners.
Apartment Manager helps family apartment owners manage guest arrivals, departures, booking fees, deposits, balances, and notes through a natural chat-style interface and multilingual Gemini AI workflows.
Public beta testing is open through Apple TestFlight, strictly limited to the first 50 installations. Read the full project details →
