About Mihai
Senior Software Engineer with 25+ years of professional experience delivering robust desktop, embedded, web, mobile, and hardware-integrated software solutions.
I specialize in Qt C++ desktop applications, embedded systems, custom hardware integration, and full-system software development involving desktop apps, backend APIs, databases, mobile apps, and web dashboards.
My work usually involves complete technical systems rather than isolated components: hardware devices, desktop control applications, backend services, databases, admin interfaces, and mobile access where needed.
Core expertise:
- Qt C++ desktop applications for Windows and Linux
- Embedded and IoT systems: AVR, RFID, sensors, GSM devices, microcontrollers
- Hardware-software integration and low-level communication
- Web applications, backend APIs, admin dashboards, and database systems
- Mobile applications connected to backend systems or hardware devices
- Database-driven applications: SQLite, MSSQL, MySQL
- Business-critical, ERP-style, industrial, public-sector, and automation systems
I work end-to-end, from requirements analysis and architecture to implementation, testing, deployment, and delivery. I am comfortable working independently or joining an existing team, taking ownership of complex technical challenges and delivering production-ready solutions.
