FiatLux Software
A focused set of things we do well, for businesses that need software built or connected and for agencies that need development under their own brand. Each one goes from first call to production with the engineer who builds it.
Marketing sites, catalogs, and online shops, from a clean cash-on-delivery setup to a full storefront. Fast to load, easy to rank, and easy for you to run after launch.
Dashboards, customer portals, and internal tools that replace a stack of subscriptions. Built once, owned by you, with real auth and data behind them.
Make your systems talk to each other: CRM, accounting, payments, online shops, and third-party APIs. Python automation for the reports, imports, and copy-paste work your team does by hand.
Lower-level work on code that has to be fast and stable: processing pipelines, engine logic, native modules, and speeding up code that has become a bottleneck.
Practical AI where it earns its place: assistant features, search over your own documents, and automation for the repetitive work, with sensible guardrails.
Keep what we built running, or hand it cleanly to your own team. Documentation, monitoring basics, and updates, so nobody is locked out of how it works.
We talk through what you're trying to do and whether we're the right fit. No charge, no obligation. If we're not right for it, we'll say so.
We agree, in plain language, on what's being built and why. Then a clear scope and a quote, fixed-scope or hourly, whichever suits the work.
You see progress as it happens, not just at the end. Short feedback loops, no surprises, decisions made with you.
We ship it, document it, and make sure you or your next developer can run it.
When your developers are fully booked, or a project needs a stack you don't have in-house, we build it under your brand. Your client never hears from us.
Mutual NDA before you share the brief. We never contact your clients, and nothing we deliver carries our name: not in the footer, the meta tags, or the code comments.
We work in your repository, follow your coding standards and review process, and leave documentation your team can use after handover.
A fixed price from a short written brief, an agreed number of revision rounds, and every change reviewed on staging before anything goes live.
Try us on a small, paid task before trusting us with a full project. Rights to the code pass to you on payment.
From Croatia, our afternoon overlaps the US East Coast morning for calls, and everything else runs on written updates you can read on your own schedule. Send us the brief.
Every project starts with a free call and a clear quote. We price by the shape of the work: fixed scope where that fits, by the hour where it doesn't. No surprise line items. Tell us what you need and you get the numbers in writing.
Presentation sites and custom web apps are quoted per project at an agreed, fixed scope, so you know the price before any code is written.
Ongoing C++ work, changes, and technical advice are billed by the hour, with a clear estimate up front and only the hours actually worked.
A script or automation that solves one defined problem is priced per solution, as a single, agreed deliverable.
Keeping software running is a flat monthly retainer, agreed in advance, so support is predictable rather than billed in a panic.
Tell us what you're building, or what's stuck.

A few sentences about the project, your timeline, and what success looks like is enough. No prep needed. We read every message and reply personally, usually within a day or two.
