Summary
👤
Senior🎓
Top SchoolMuhamad Winata is a mobile-focused software engineer with 11 years of experience and 7+ years building native Android (Kotlin) and cross-platform Flutter apps that prioritize UX and business impact. He combines Spec-Driven Development with an AI-native workflow—using GLM models and Claude Code agents—to accelerate delivery 3–5x while acting as the technical decision-maker and quality gatekeeper. Muhamad has shipped six Play Store apps, one productivity app with 10,000+ downloads and a 4.4 rating, and implemented payment and ML integrations (Midtrans, Google ML Kit) across production systems. His background spans e-commerce, community platforms, and logistics, including optimizations for low-end devices and unreliable networks. Based in Jepara, Indonesia, he pairs hands-on coding (Kotlin, Flutter, Riverpod) with end-to-end delivery expertise from PRD to Google Play publishing. Less obvious: he systematically documents and verifies technical specs before implementation, which he credits for reducing client misalignment and maintaining high code quality despite rapid, AI-augmented development.
