Backend, desktop, web and the hardware in between.
Based in Liberec, Czech Republic. A one-person studio that takes the jobs most agencies quietly decline.
Expertise
Nine departments, one developer. Everything below is work I do myself — from the database schema to the cable in the ceiling.
01.
Backend
ASP.NET CoreREST APIsSignalREntity Framework
Server-side applications, RESTful APIs and microservices. Database design across MySQL, PostgreSQL and SQLite.
02.

03.
Web

Full-stack web work in Blazor, ASP.NET Core and Razor Pages. Responsive frontends, real-time dashboards, landing pages and robust APIs.
04.
WordPress

I maintain and customise existing WordPress sites when required. For a new project, real code is the better answer — and I will say so.
05.
Embedded

IoT and embedded interfaces, hardware-software integration, custom firmware and protocols. Industrial control panels assembled on request.
06.
Surveillance

Full IP video system design, installation and configuration — cameras, recorders, networking and cable runs.
07.
Databases

Schema design, query optimisation, migrations, and the rescue of tables long thought lost. MySQL, PostgreSQL, SQLite.
08.
Linux
nginxsystemdTLSBackups
Deployment, hardening, certificates and backups. From bare metal to containers, with monitoring that actually pages someone.
09.
Microcontrollers
ArduinoESP32SensorsMotors
Real devices that bridge code and the physical world. Sensors, motors, relays, buttons and displays — prototypes and finished products that react to what is around them.
Projects
Shipped work, filtered by what it is made of. Some entries stay nameless — private commissions do not get a public link.
Process
No account managers, no hand-off between four departments.
You talk to the
person writing the code.
We work out what the thing actually has to do, and what it definitely does not. Honest estimate up front, including the parts that will hurt.
Data model, services, deployment target. Decisions get made early so they do not become expensive later.
Iterative delivery with something runnable at the end of each stage. You see progress.
Linux servers, certificates, backups and monitoring. Handover documentation, or ongoing maintenance if you prefer.
