## About

Cronsoft rescues and builds operational software for teams dealing with legacy systems, hardware-connected workflows, and device-backed platforms.

Our primary focus is C++/C# rescue: reverse engineering, build recovery, CI/test scaffolding, stabilization, memory/performance work, and controlled modernization including Windows-to-Linux porting. We help teams recover systems that no longer build reliably, crash in production, depend on tribal knowledge, or have become too risky to change.

We also build hardware-connected applications: production control software, station applications, traceability systems, device provisioning tools, and QA/test workflows. Our experience includes C++/Qt/QML workstation software controlling production-line tooling via serial/TCP, barcode scanner integration, BLE testing, and traceability from PCB intake through final lot assignment.

For connected systems, we build mobile apps and server infrastructure around real devices: BLE/BT mobile applications, telemetry ingestion, admin portals, installer utilities, and operational dashboards. One deployed system processes data from 20k+ LoRa collectors across two cities.

Most work is delivered by a small senior team. We emphasize reproducible builds, CI, clear handover, documented risks, and exit-ready delivery so clients are not locked into us.

Best-fit projects include legacy C++/C# stabilization, build recovery, Windows/Linux migration, Qt modernization, hardware-adjacent operational software, BLE mobile apps, and device telemetry platforms.
