Hi, I'm Arif Syaiful Anwar — building enterprise web systems and cross-platform mobile apps with ASP.NET Core, Flutter, Kotlin, Python, and SQL Server. From cooperative ERP to IoT smart devices.
I'm Arif Syaiful Anwar, a Full Stack & Mobile Developer specializing in enterprise systems for cooperative, retail, financial, and legal organizations, plus Android and cross-platform mobile apps.
My work spans ASP.NET Core backends with layered architecture, Flutter & Kotlin Android apps, Python AI services, browser automation with JavaScript, and IoT devices with C++/Arduino/ESP8266.
From multi-step approval workflows and face-recognition attendance to payment gateways, document encryption, and smart sensors — I build real solutions with clean, maintainable code.
Not just the final result — this is the real process of how I build every system from scratch to production.
