Cronsoft specializes in creating and restoring operational software for teams working with legacy systems, hardware-integrated workflows, and device-based platforms. Our main expertise lies in C++/C# recovery, which includes reverse engineering, rebuilding processes, continuous integration/testing frameworks, system stabilization, and optimization of memory and performance. We also facilitate controlled modernization tasks, such as porting from Windows to Linux. Our goal is to assist teams in reclaiming systems that are unreliable, crash during production, rely too heavily on specific personnel, or have become too risky to modify. Additionally, we develop hardware-integrated applications, including production management software, station applications, traceability systems, device provisioning tools, and quality assurance/testing workflows. Our background encompasses C++/Qt/QML workstation software that manages production tools via serial/TCP connections, integrates barcode scanners, conducts BLE testing, and ensures traceability from PCB intake to final lot assignments. For connected systems, we design mobile applications and server infrastructures revolving around real devices, such as BLE/BT mobile apps, data ingestion for telemetry, administrative portals, installer utilities, and operational dashboards. One of our implemented systems manages data from over 20,000 LoRa collectors in two cities. Most of our work is executed by a small, senior team. We prioritize reproducible builds, continuous integration, clear project handovers, documented risks, and exit-ready delivery to ensure that clients are not dependent on us. Ideal projects include stabilizing legacy C++/C# systems, rebuilding processes, migrating from Windows to Linux, modernizing Qt applications, creating hardware-related operational software, developing BLE mobile applications, and creating platforms for device telemetry.
