Alperen S.

Mobile Developer | IoT | Bluetooth | Tuya Expert

Hello, I’m Alperen, a Mobile IoT Engineer with 4+ years of experience building mobile applications for connected devices. I have professional experience at one of Europe’s leading TV and home appliance manufacturers, where I worked on smart home and IoT products used in real production environments. My main focus is mobile development for Bluetooth, BLE, WiFi onboarding, device provisioning, and smart device integrations. I have hands on experience with Tuya based devices and with building reliable mobile flows for device discovery, pairing, control, and status monitoring. I also worked on SDK development, feature implementation, bug fixing, app maintenance, and release management in multicultural Agile teams. I work across Flutter, React Native, Swift, and Kotlin, depending on the product needs. I can help with cross platform mobile apps, native integrations, IoT device communication, and performance focused user experiences. My goal is always to build solutions that are stable, maintainable, and ready for real users. If you are looking for someone who understands both mobile development and connected device logic, I would be glad to support your project.
