gljivobook.app
Public appA field guide to 169 mushroom species, an on-device identification tool and an offline field journal.
I build apps from idea to launch.
I’m Vedran Zrinski. I’ve worked in the automotive service trade for twenty years, and in my spare time I design, code and publish my own web apps — from a field guide for mushrooms to a family recipe vault.
AI is a tool, not a substitute for thinking: I own the requirements, decisions, design, testing and security, and AI speeds up the building.

From the service workshop
Tools for car washes, tyre shops and workshops, born from my real working experience. Carwash and Tirehotel are currently being moved to a more modern, more user-friendly interface. alatnica.app was recently moved from Google Apps Script to a new trial interface you can try out.

How I work
- 01
Listen
I start from a real problem and the person who has it, not from the technology.
- 02
Design
I sketch a flow and interface that makes sense for older users and in the field.
- 03
Build with AI
I prototype fast, and I check every decision, test and security rule myself.
- 04
Ship
An offline-capable PWA, clear privacy and a release someone can actually use.
About me
For over twenty years I’ve worked with people and processes in the automotive service trade, and today I am a certified service advisor, senior specialist: every day I turn other people’s problems into a clear repair plan. There I saw how many good ideas die because of unsuitable tools.
So I started building my own. Most projects came from a concrete need — mine, my family’s or my colleagues’. I’ve learned React, TypeScript, PWAs, Firebase and working with AI models, and I’m especially interested in turning an idea into a product that is simple, safe and useful.
For years I have also run a cooking channel on YouTube, @Vekiukuhinji, with over 600,000 views and more than a thousand subscribers. It taught me to explain things step by step, and it is where the idea for Mamina Teka came from.
I’m not actively job-hunting right now, but I’m open to interesting roles and projects in app development, AI and product design.
What I work with
Have a problem no ready-made app solves?
Describe it to me. If I can solve it, we’ll try to build the app exactly the way you imagined it. Everything I publish is free. If you want an app tailored just for you, get in touch by email.
