Dmytro Kravets

I build production systems where physical equipment meets real money, from SamWash self-service car washes to industrial edge controllers. My software has processed more than 14 million payment transactions while controlling equipment, collecting telemetry, and reconciling daily revenue.

For SamWash, I built bay control and remote management around Modbus RTU/TCP, C# tablets, bill and coin acceptors, card terminals, and QR payments. I design for unreliable connectivity, buffering events at the edge and backfilling them when links return.

I also built Defender-3, a WhatsApp-based sales automation system that takes orders from first message through shipment, generating contracts, invoices, delivery notes, and carrier waybills. It has handled 256 orders worth UAH 23.3M and automatically generated 208 documents.

Across Plantpol and NRC Zaporizhzhia, I build commerce platforms, multilingual course systems, bots, APIs, and interactive 3D web experiences. I bring firsthand factory experience to architecture decisions: what a system must survive, how it behaves when a link drops, and how it performs under real load.
