Designed for your business. Built around your day.
Choose an example to see how your tasks could connect.
A form submission becomes a customer record, a confirmation and the next task.
The right technology for the task
Zapier, Make, n8n or custom development — I use what fits the way you work.
We can start with one clearly defined task and connect the solutions later.
Thoughtful design, clear content and an easy way to get in touch. Business websites, online shops and custom web systems.
I connect the tools you already use. Data goes to the right place, and recurring tasks start automatically.
Document processing, knowledge search or draft replies. AI chosen for the task, with the right review points.
We start with a clear plan. I build a solution you can put to work.
We talk through your goal, how things work today and where the work gets stuck.
I define the task, the solution and the scope with you. You’ll know what’s being built.
I develop the solution and connect your tools, then we test the workflow together.
I show you how to use it, and we discuss options for support and further development.
I’m Gergő Reiner, founder of KERNUM². I bring web solutions, automation and 3D design together to fit the task.
You work directly with me, from the first question to the finished solution.
SAVARIA3D is the 3D side of KERNUM². I design custom parts and print prototypes and small production runs.
DIGITAL → PHYSICALYes. A business website, landing page or online shop can be a project on its own. We can add automation later.
First, I check which connection options your tools offer. If there’s a suitable integration or API, I plan the data transfer. We’ll clarify any limits before I send a proposal.
That depends on the size of the task and the connections it needs. After a short conversation, you’ll get a proposal with a defined scope, schedule and price.
I use AI when it helps with the specific task. Many workflows can be automated well with simple, predefined rules.
Tell me what you need. A website, a recurring task or an idea that’s still taking shape is a good place to start.
