Web and mobile apps
Custom websites, online stores, and mobile apps for Android and iPhone from a single codebase — one build instead of two, and a shorter timeline. Backends, APIs, and integration with the systems you already run.
Software studio Croatia
A small studio. You deal directly with the person writing the code — and you get a fixed quote and a finish date before any work starts.
Services
Custom websites, online stores, and mobile apps for Android and iPhone from a single codebase — one build instead of two, and a shorter timeline. Backends, APIs, and integration with the systems you already run.
An assistant on your site that answers customer questions from your own content, around the clock, and cites where each answer came from. It takes enquiries and bookings, and hands anything that needs a person to your team. Works in Croatian and English.
Structured data pulled from public sources and delivered clean: product catalogues, directories, listings, competitor pricing. Every delivery ships with a validation report, so you can see the data is complete rather than take our word for it. Company-level data only — no personal data.
Technical SEO, page speed, structured data, local search and Google Business. Fixing the reasons customers currently don't find you.
Selected work
Full-stack grocery price comparison app
A Spring Boot backend with PostgreSQL and a React Native client. It handles over 100,000 products behind a caching layer, and uses fuzzy matching to reconcile the same product listed under inconsistent names across different retailers.
Production scraper for the MapYourShow platform
A three-stage pipeline with a six-check validation suite. It extracted 2,582 exhibitor records, with completeness proven against the source's own reported total — no failures and no duplicates. The code and the full write-up are public.
Hiring signals from public job boards
Tracks open roles across Greenhouse and Lever job boards, diffs each run against the previous one, and reports what changed per company instead of listing jobs. The published run covers 11,722 deduplicated roles at 164 companies across 62 countries, collapsing 3,182 duplicate postings. Ten validation checks gate the output, and the report renders as one self-contained file with no network requests.
How we work
We work out what the software actually has to do before anyone talks about building it. You don't need a specification — that's our job.
You get a price and a finish date in writing before work starts. The price doesn't move unless you ask for something that wasn't in it.
No account manager in between. The person answering your email is the person writing the code, so nothing gets lost being relayed.
Contact
Describe the problem in a couple of sentences — that's enough to start. You'll get a real answer about whether it's worth building, and what it would take.
