Nurkholish A.

8+ years of professional experience delivering production software across Desktop, Android, Web, and Embedded/IoT - for industrial, research, and hobbyist clients. Top Rated Plus with $300K+ earned and 11,000+ hours on Upwork. I work as a generalist who ships end-to-end: from PCB and firmware up to dashboards, mobile apps, and cloud integrations. I also leverage modern AI-assisted development (Cursor, Claude, Copilot) to ship faster without compromising quality - pairing it with strong fundamentals in C/C++, debugging, and architecture. What I can build for you: - Cross-platform Desktop apps - Qt, .NET (C#/VB.NET), C++ - Android apps - Java/Kotlin, BLE, GPS, hardware integration - Web apps & dashboards - JS/TS, REST APIs, IoT dashboards, Webflow CMS - Embedded & IoT - AVR, ARM, ESP32/ESP8266, Arduino, Embedded Linux - PCB Design - KiCAD, Eagle, EasyEDA - Connectivity - MQTT, BLE, LoRa, GPRS, RF, TCP/IP, RabbitMQ Languages & tools: C, C++, C#, VB.NET, Java, Python, Go, Swift, JS - Qt, .NET, Android Studio, PlatformIO, Xcode - MySQL, SQLite, JSON - Linux, Windows, macOS, Embedded Linux, Android. Long-term collaborations welcome - I'm currently supporting multiple clients on monthly retainers (sensor monitoring, IoT dashboards, embedded device support). Let's talk about what you're building.
