I build real-time operational systems for hospitality.
I am Lukas Slivka — a software developer, hospitality operator, and builder of systems that need to work under live service pressure. My focus is not just interface design. I work on the operational layer underneath: how guests interact, how staff respond, how management gains visibility, and how software can extend into the physical environment itself.
My flagship product, QRelia, is the clearest expression of that approach — a live hospitality platform that connects guests, staff, management, and device-level feedback into one coordinated real-time system.
- .NET / Razor Pages / SignalR
- Hospitality domain expertise
- Hardware-integrated systems
- Production-first mindset
I work where operational reality and software architecture meet.
The difference in my work is not just technical breadth. It is the ability to understand live operations, translate that into product logic, and then deliver the system end-to-end. That means building for timing, coordination, visibility, edge cases, and real usage instead of abstract feature lists.
Deployment & infrastructure
Linux-based deployments, VPS hosting, Apache reverse proxy, Kestrel services, and systemd orchestration — built so products can move from idea to live environment without handoffs.
System architecture
Full-stack systems using .NET, Razor Pages, and SignalR, designed for real-time consistency, operational clarity, and multi-tenant SaaS evolution.
Operational understanding
Built from real hospitality experience — translating service pressure, handovers, and workflow friction into systems that improve clarity, coordination, and response time.
From product model to production delivery.
I build complete systems — not just backend logic or UI. That includes payment infrastructure, subscription models, onboarding flows, communication layers, and interface decisions that make a product commercially viable as well as technically sound.
Stripe
Payments, payouts, subscriptions, billing flows, and connected accounts — enabling full SaaS monetization and platform-style architectures.
Brevo
Transactional email, communication flows, and operational messaging integrated directly into product workflows.
Frontend systems
Chart.js, THREE.js, SweetAlert2, and modern JavaScript tooling used to build dashboards, visual experiences, and responsive interfaces.
QRelia — a system that turns guest actions into operational signals.
QRelia was developed and deployed in a live hospitality environment. It turns guest interaction, staff workflow, management visibility, and device feedback into one coordinated layer so the venue can respond faster, reduce friction, and remove blind spots across the operation.
Hospitality-first thinking
Systems designed around real service flow, not assumptions.
Real-time architecture
Instant state propagation across interfaces using SignalR.
Device layer integration
Lighting and hardware feedback translating system state into physical signals.
QRelia is the flagship. The rest of the portfolio is supporting proof.
Alongside QRelia, I have built multiple systems across hospitality and service industries. These projects matter because they show a repeatable pattern: identifying operational friction, structuring the workflow, and turning that structure into software that people can actually use.
BarberCore
Service-business SaaS platform with booking, payments, and client flow management.
InnControl
Internal hospitality coordination system focused on operational visibility.
Room Service System
Early system exploring digital ordering and service workflow execution.
Software is most valuable when it changes how the operation behaves.
That is the direction behind my work — real-time systems, clearer workflows, and products that hold up in live environments rather than only looking polished in isolation.
