Production systems.
Not concept videos.
Real products, shipped and live. Here's what we've built - and what you can use today.
Voter support statements printed straight from the ID card
A desktop app for collecting signatures for an electoral list in Serbia. The voter inserts their ID card into a USB reader, Okno reads the chip and prints the filled-in NPRS-3 declaration in seconds - no transcribing, no forms rejected for typos. It checks age, citizenship, JMBG and duplicates before printing, keeps only what the RIK voter list needs, and works offline on Windows, macOS and Linux.
The same ID-card flow, for national minority council elections
Okno's sibling for Serbia's national minority council elections. It reads the ID card chip and prints the official RIK statement form for any of the 19 directly elected minorities - bilingual where the law requires it - and transcribes names like SZABÓ ERZSÉBET into Serbian Cyrillic by the rules of that minority's language. It checks the separate minority voter register, prints the registration request when a voter is missing, and exports the list straight into RIK's Excel template. Installs side by side with Okno.
Real-time vocal removal in any browser tab
A Chrome extension that turns any song playing in a tab into a karaoke track - no download, no upload. Local DSP for instant results, with optional AI vocal separation (Demucs) for studio-grade stems.
An open lyrics database built for karaoke
An open-source, LRCLIB-compatible lyrics API with word-level timing, duet parts, and account-free community corrections - immutable revisions, anonymous quality signals, and proof-of-work abuse control. It's the data backbone behind Karafilt's synced lyrics.
Keep the vocal, mute the band - play along in any tab
A browser extension that flips karaoke for musicians: it isolates the lead vocal and mutes the band so you can play the missing parts yourself. WebAssembly DSP runs entirely in the tab - no uploads - with auto-generated chord charts synced to lyrics, plus transposition and capo tools. Free, open source, and built on the same backbone as Karafilt and Karalyr.
Our AI engineering partner
Century AI is our partner company - a close collaborator we build alongside, sharing engineering capacity and applied-AI expertise across joint projects so clients get a deeper bench without a bigger vendor list.
WordPress web application, built end to end
We developed Ambient's web application on WordPress - custom theme, tailored functionality, and a maintainable CMS the team owns and updates themselves, with no lock-in to a bespoke stack.
New web app engineered for ads, SEO and ranking
We built DIV Polymer's web application entirely from scratch - engineered to power their ad campaigns with stronger SEO foundations and higher Google rankings, turning paid traffic into measurable growth.
A pancake shop's website, with ordering built in
A storefront for a Novi Sad palačinke and krofnice shop - a 48-item menu, a persistent cart, and checkout with pluggable online payment and order status. Three runtime dependencies total, so it loads fast on a phone standing outside the shop.
