Project 01 / 04

Property Manager

The system behind a Croatian villa-rental brand: a booking site guests use to check dates and reserve, and an admin panel where the owner runs listings, prices and content. Both sides read the same records, so the public site and the admin never disagree about a property, a price, or an open date.

A stay's price is built night by night, and bookings are checked against real check-in and check-out times, so one guest can leave and another arrive on the same day without a clash.

The public site and the admin never disagree about a property, a price, or an open date.

Household

A self-hosted, installable web app that turns running a home — shopping lists, recipes, loyalty cards, to-dos — into a lightly gamified shared space. A Laravel 13 JSON API backs a Vue 3 + TypeScript SPA, with real-time list sync over WebSockets and Web Push notifications.

Loyalty cards live in a zero-knowledge vault: numbers are encrypted in the browser with a PBKDF2-derived key, and the server stores only a salt and an opaque authenticator. Grocery price comparison reaches a separate prices service over an authenticated HTTP API, with no shared database.

Real-time where it helps, zero-knowledge where it counts.

Adriatic Sea

An environmental monitoring platform built for the Croatian Hydrographic Institute, managing a network of coastal stations along the Adriatic: tide, waves, wind, pressure and meteorology, each writing into its own per-station data tables.

Instrument files are parsed per station, calibrated against tide datums, and watched by a threshold alarm system. Public station pages show the latest readings to anyone, refreshing themselves on a timer and flagging data that stops arriving.

Scoreboard

Software for clubs and leagues that run their own football competitions and want to show them live. A pitch-side LED scoreboard lights up the moment a goal is recorded, driven by an operator on a phone at the sideline.

The score and clock are kept on the server, so the board is always right — even after a power cut mid-match. Around it sits a full competition: clubs, teams, players, seasons and results, with each operator running only their own.

An operator on a phone at the sideline drives the whole board.
