Dhaval D.

I design and deliver production-ready IoT systems with ThingsBoard as the core platform, supported by reliable embedded firmware and high-performance mobile applications. My focus is on scalability, security, and long-term maintainability—not demo or PoC-only solutions. ThingsBoard Platform Development I deploy, configure, and customize ThingsBoard Community and Professional Editions as the backbone of IoT platforms. Key Capabilities - Architecture & edition consultation - Rule chain design and performance optimization - Custom rule node development (advanced logic, token handling, external services) - Secure device provisioning, claiming, and bulk onboarding - Role-based access control and multi-tenant hierarchy design - Responsive dashboards and custom widgets - External integrations (authentication ex.descope, billing ex. stripe, ERP/CRM systems) - All ThingsBoard implementations are production-focused, designed to scale smoothly as devices, tenants, and users grow. IoT Firmware & Gateway Development I develop production-grade firmware for IoT devices and gateways, ensuring stability, security, and long-term field reliability. Chipsets & SDKs - Espressif ESP32 series (ESP-IDF, Arduino) - Nordic Semiconductor nRF series (nRF Connect SDK) Protocols - Wi-Fi, MQTT - BLE, BLE Mesh - Zigbee, Matter - Gateway Development - Protocol translation (BLE/Zigbee → MQTT/HTTP) - Local data processing and edge logic - Reliable gateway-to-cloud synchronization Production-Ready Features - OTA firmware updates - Secure boot and device authentication - Power optimization - Error handling, recovery, and diagnostics logging IoT Mobile Application Development I build high-performance mobile applications for IoT ecosystems using native (iOS/Android) and Flutter-based hybrid approaches. Mobile apps are commonly used for: - Device provisioning and configuration - Monitoring, control, and diagnostics - Secure interaction with devices, gateways, and cloud platforms Wireless & Device Technologies - BLE, BLE Mesh - Matter - UWB, RFID For performance-critical or healthcare-grade use cases, I develop fully native iOS apps to ensure: - Low-latency and stable BLE communication - Reliable background operation - Precise control over system resources - Mobile apps integrate seamlessly with ThingsBoard, ERP systems, and third-party services using secure APIs. Why Clients Work With Me - ThingsBoard-first architecture mindset - One engineer covering device → cloud → mobile - Strong production and scalability experience - Clean, maintainable system design If you need a ThingsBoard-centric IoT solution backed by solid firmware and mobile applications, I can help.
