I build what you cannot buy off the shelf.
Software, electronics and technical consulting from one source — for businesses whose task is too small for an agency and too specific for standard software.
Three fields, one contact
Most tasks fall between the chairs: the software vendor does not know the machine, the electronics engineer writes no reports, the consultant builds nothing. I cover all three sides.
- Field 01
-
Software and automation
Business tools instead of spreadsheet chaos: inventory, quotes, order management, reporting. Plus interfaces between systems that do not talk to each other, and automation of recurring routines.
Python · FastAPI · Flutter · n8n · web applications
- Field 02
-
Electronics and embedded
From the circuit to the device in the field: schematic, PCB layout, firmware, sensors, radio links, solar operation, enclosure. On request including manufacturing and assembly.
KiCad · ESP32-S3 · LoRa · BLE · sensors · MPPT solar

Technical consulting and prototyping
Settle feasibility before money is spent. Forty years of practice in metering, dosing and UV technology, plant construction and commercial dishwashing — plus the workshop to show an idea as a working prototype.

How working together goes
In writing, at a fixed price, without chains of meetings. You describe the task, I write back what I deliver and what it costs.
Enquiry. You describe the task in a few sentences — e-mail or the form is enough.
Questions and quote. Within two business days you receive a written quote with scope, fixed price and delivery date.
Implementation. I work, you get intermediate versions to look at. No meetings needed if you do not want any.
Handover. Delivery with documentation. The source code belongs to you.
