Fourteen years as a software engineer, eleven of them shipping for Apple platforms: satellite AR tools, banking, pharmacy, video, and Philips IoT used by tens of thousands. Evenings are for my own apps. Eight shipped so far.

The apps
Five live on the App Store, and three retired veterans below.
Your life in weeks · private digital wellbeing for iPhone
Your life is about 4,170 weeks. Drift draws the dark ones already lived and the pale ones still yours, then shows where your evenings are taking them. One honest answer a night, one quiet verdict a week, and no streaks or resets.
You read the book. Two months later it's gone. Kern turns any finished book into key-idea cards in seconds, then brings them back with spaced repetition until they stay. The Wall shows every book you've read, and fades them as your memory would.
"You don't die from one bad decision. You die from who you slowly become." A swipe-driven survival diary set after the collapse. Four needs on screen (food, shelter, mind, body) and five personality axes shifting invisibly underneath. 200+ cards, branching paths with locked consequences, and endings decided by who you became along the way.
There's a conversation you've been avoiding. This app walks you to it: name it, face what you're afraid of, decide what actually needs to be said, put it on the calendar, follow through. Linear by design. You use it once, you have the conversation, you're done.
A calm bedtime ritual for families. A structured wind-down, personalized stories where your child is the hero, and quiet prompts to talk about the day before the lights go out. Built by a parent who knows exactly how 8 p.m. feels.
Earlier work
Off the store now, but each one taught me something I still use.
Real-time PvP, comic-strip endings
Intergalactic gladiators, simultaneous 20-second turns, 60+ abilities, and every battle ended as a comic strip you could share. Debut game of our three-person Croatian indie team. I built the entire iOS app in Objective-C with cocos2d, including a custom TCP networking layer for the real-time multiplayer, written from scratch.

A minimalistic vocabulary builder
Type, scan or speak a word to define it and save it, then make it stick with short word games. Spaced learning before I knew to call it that.
📥 80,000+ downloads before retirement
Baby photo art for new parents
1000+ hand-made artworks, typography and filters to mark first moments and milestones. Swipe the strip to see plain photos become keepsakes. One-time purchase, no subscriptions, on principle.
About
I started in 2011 writing Java for the satellite industry, then taught myself iOS and Android because my team needed someone who could. Four years later I was leading the mobile team. Since then it's been banking, pharmacy, travel, video editing, EV leasing, and IoT. Seven of those years I worked fully remote through Toptal, across twelve projects.
These days I work as a senior iOS developer on IoT products by day, smart smoke detectors and automatic gear shifting for e-bikes among them, and ship my own apps at night from Požega, Croatia. I care about code that survives the person who wrote it: SOLID, tested, reviewed. And about shipping, because an app that never ships teaches you nothing.
Experience
Senior iOS developer on IoT products: smart smoke detectors, automatic gear shifting for e-bikes, and more. Earlier, led iOS on the Philips Home Safety app, with secure real-time camera streaming, two-way communication and alerts for tens of thousands of users, plus the Philips Pet Series app. I own the CI pipeline and keep the codebase honest through reviews.
Java for the satellite industry, then self-taught mobile. Built and maintained 4 iOS and 4 Android apps, including an AR satellite-antenna alignment tool used by disaster-relief field operatives. That one made me solve gimbal lock the hard way, in Objective-C, because "close enough" meant a lost comms link.
