You will get Custom IoT & Embedded System Firmware Development
Project details
You will get a reliable, production-ready IoT and embedded system solution designed for real-world deployment. I develop custom firmware and connected device architectures using ESP32, STM32, Arduino, and industrial controllers, integrating secure cloud platforms like AWS IoT Core and MQTT with TLS encryption.
From sensor integration and Modbus communication to OTA updates and real-time monitoring dashboards, I build scalable systems that ensure stable connectivity, efficient power usage, and secure data transmission. Whether you need a smart energy monitor, industrial gateway, automation controller, or remote monitoring device, I create modular and maintainable firmware tailored to your requirements.
My approach focuses on performance, security, and long-term scalability — ensuring your IoT product is ready for commercial deployment.

Chess Mobile App for IOS and Android
Abdullah K. was a pleasure to work with on our mobile app development project. He demonstrated exceptional expertise in Flutter and Kotlin, delivering a high-performance, scalable application that exceeded our expectations. His attention to detail, clear communication, and commitment to on-time delivery made the entire process seamless. We highly recommend Abdullah for any mobile app development needs and look forward to collaborating with him again in the future.
About Abdullah
Flutter & Kotlin Mobile Developer | Scalable Android & iOS Apps
Bahria Town, Pakistan - 7:46 pm local time
I'm Abdullah, a Mobile App Developer with 5+ years of experience building production-grade Android and iOS applications using Flutter, Kotlin, Swift, and Dart. I recently delivered a cross-platform Chess app for iOS and Android, rated 5 stars by the client for scalability, performance, and clean architecture.
Whether you're a startup launching your first MVP or a business scaling an existing product, I build apps that work reliably, look polished, and are easy to maintain long-term.
⫸ What I build
• Cross-platform apps with Flutter & Dart (single codebase, Android + iOS)
• Native Android apps with Kotlin & Java
• Real-time features, live chat, tracking, push notifications
• Secure authentication systems (JWT, OAuth, Firebase Auth)
• Payment gateway integrations (Stripe, in-app purchases)
• REST API & Firebase backend integration
• App Store & Play Store deployment
⫸ Why clients work with me again
I don't just write code; I think about your product. Before touching a line, I map out your architecture, flag potential bottlenecks, and make sure we're building something that can grow. My clients get clean, documented code and honest progress updates throughout.
Past work spans e-commerce apps, healthcare appointment systems, fintech platforms, delivery tracking apps, and real-time chat systems.
⫸ If you have an app idea, a broken build, or a product that needs a performance overhaul, let's talk. I respond within 4–8 hours, and I'm available for both short-term projects and long-term contracts.
