An app is only as good as the database beneath it.
We build custom web apps, mobile apps and SaaS platforms — together with the data layer that keeps everything fast, secure and ready to scale.
Technologies we build with
When to reach out
Signs your current setup is holding you back
If any of these sound familiar, let's talk — often we can upgrade what you have, sometimes a rebuild pays off more.
Everything runs in Excel
Your data lives in spreadsheets you manually copy between tools.
Your tools don't talk
Store, CRM and accounting each work in isolation, with no links.
Off-the-shelf isn't enough
Your process is too specific for standard software.
The app is slow
With more users or data, the system starts to stutter.
No one maintains the code
The previous developer left and nobody dares to change anything.
You need a mobile app
Your customers expect an app on their phone, not just a website.
What we build
From idea to a product your customers actually use
A public web app, an internal tool or a mobile app — we cover the whole development path.
Custom web apps
Portals, booking systems, internal tools and dashboards tailored to exactly your process — no bloat and no monthly licences for features you never use.
- Dashboards
- Booking
- Internal portals
- Automations
Mobile apps
iOS and Android from one codebase — one product, both platforms.
- Flutter
- React Native
SaaS platforms
Multi-tenant platforms with subscriptions, billing and roles. We built Virtualna Pisarna ourselves — we know what such a product takes.
- Subscriptions
- User roles
- Multi-tenant
Integrations & API
We connect your existing systems — store, CRM, accounting, suppliers — so data flows on its own, with no manual re-entry.
- REST & GraphQL
- Sync
- Payment systems
Online stores
WooCommerce and custom builds, optimised for speed and completed checkouts — connected to your stock and logistics.
- WooCommerce
- Custom
- Stock sync
Maintenance & support
Development doesn't end at launch. We handle updates, security, backups and upgrades as the business grows.

The foundation users never see
The database decides whether the app will hold up
We design the data model carefully from the start — so the app doesn't slow down as data and users grow, and so your data stays connected, consistent and always reachable.
Data model design
We design the database to reflect your real business — not the other way around.
Migration & data cleanup
Moving from Excel or a legacy system, with no loss or duplication.
Performance tuning
Indexes and queries set up for fast responses even with large volumes.
Security & backups
Access control, regular backups and protection of sensitive data by best practice.
How we work
A transparent process, no surprises
You know what's happening at every step — and the code is yours from day one.
Understand
We get to know your business, users and goal. Together we set the scope and priorities.
Architecture
We design the data model and technical structure — the foundation we build on.
Build
We build in short cycles, showing progress as we go and leaving room for changes.
Launch & grow
We ship, monitor performance and keep improving as the business grows.
Why Reworq
Developers who also think about your business
We're not just programmers — we're an agency that understands marketing, data and sales. That's why the apps we build work in the real world, not just in a demo.
One team for everything
Development, design, SEO and marketing under one roof — no project stuck between vendors.
You own the code
No lock-in with a single provider. We hand over access and documentation.
Our own SaaS product
We built and run Virtualna Pisarna ourselves — we know what running a product long-term means.
Post-launch support
We don't disappear after handover. We stay available for upgrades and maintenance.
Measurable from day one
We build analytics and tracking into development — so you know what users actually do.
Direct contact
You talk to the people actually building the project, not a middle-man account manager.
Frequently asked
Before you decide
It depends on scope. A small internal tool and a full SaaS platform are two very different projects. After an intro call we prepare a clear quote broken into phases, so you know what you're paying for.
Smaller projects can be done in a few weeks, larger platforms take several months. We work in short cycles, so you see working versions early — not only at the end.
Yes. The code, access and documentation are yours. If you ever move to another developer, they can continue where we left off — no dependency on us.
Often, yes. We first review the existing code and database, assess the state and honestly tell you whether an upgrade or a rebuild makes more sense — no sugar-coating.
Yes. We offer regular maintenance, updates, backups and support, so you don't have to worry about the technical side after launch.
Tell us what you want to build
Describe your idea in a few sentences. In an intro call we'll clarify the scope and next steps together — free and with no obligation.
