About me
I'm an expert IoT developer with 5+ years of experience building complete systems using ESP32, ESP8266, and Raspberry Pi, paired with cross-platform Flutter apps. I handle firmware (C/C++, MicroPython), connectivity (WiFi, MQTT, BLE), and cloud integration (Firebase, AWS). My services include sensor integration, real-time dashboards, OTA updates, and clean code. I prioritize testing and clear communication to take your prototype to production. Let's bring your smart device idea to life—message me to get started.

IoT and Mobile App Developer
Fiverr • Freelance
Jan 2021 - Present • 5 yrs 7 mos
As a Flutter developer, I've built e-commerce apps with cart systems, fintech apps handling secure transactions, food delivery platforms with live order tracking, and fitness apps with real-time metrics. The cross-platform magic saves massive time—one codebase runs beautifully on both stores. Hot-reload transforms development into an interactive experience, allowing instant UI refinements. I've navigated complex state management using Riverpod, integrated Firebase for authentication and push notifications, and optimized performance for smooth animations. Each project taught me something new, from handling platform-specific sensors to ensuring pixel-perfect designs. The journey is challenging but deeply satisfying.
