I communicate clearly, provide organized deliverables, and meet agreed timelines. Available to start immediately and happy to discuss your hardware requirements and project goals.

@esol

What I understand from project detail is that, ESP32 should be used as data collector and fwder. It will act as BLE server for incoming Mobile apps BT connection and at the same time perform WIFI based data upload to your server api. I assumed everything will be developed by you i.e. mobile apps, and backend server and here we are only talking about embedded development based on ESP32. Just to let you know that I have developed embedded system for racing car based on STM32 microcontrollers and android panel. ESP32 is far less complicated then STM32 development. Kindly **DO NOT** accept my bid until we discuss this project in detail with scope of work. Ehsan.

@Webslinger01

Hi, I am an Electronics Engineer with 12+ years of hands-on experience in ESP32 firmware development, BLE communication, and PCB design. I have worked extensively with all the peripherals mentioned in your project roadmap: ✅ Temperature, humidity & motion sensors — integrated across multiple production projects ✅ GPS, LoRa & RFID modules — deployed in real-world embedded systems ✅ ESP-IDF & Arduino C++ — my primary development environment ✅ PCB design (KiCad / Altium) — from schematic capture to production-ready Gerbers ✅ Low-power BLE optimisation — stable connections with minimal current consumption Regarding your acceptance criteria, I want to assure you: — My firmware builds clean on the latest ESP-IDF release with zero warnings. — Every PCB revision I deliver passes continuity checks and Gerbers are fab-ready. — I provide a proper README and changelog with every milestone so any new engineer can continue without confusion. In addition to firmware and hardware, I have supported companies through complete product cycles — from initial prototype to mass production — including 3D enclosure design and final shipment of working units. I am fully comfortable working over Git, async communication, and scheduled video calls. I would be glad to discuss your first milestone and how we can move forward together. Looking forward to your response! Himanshu

@aditip006

Your project immediately caught my attention because it sits right at the intersection of embedded systems, IoT sensing, and low-power device development, which aligns closely with my background. During my research at the National University of Singapore, I deployed machine-learning-based signal processing algorithms on an STM32 microcontroller using TensorFlow Lite, which required efficient embedded coding, real-time data handling, and careful power management—skills directly relevant to ESP32 development. Firmware - Develop and optimize ESP32 firmware using ESP-IDF or Arduino C++ - Implement BLE services and characteristics for reliable sensor data transmission - Integrate sensors such as temperature, motion, and humidity modules - Manage communication with peripherals like GPS, LoRa, and RFID - Optimize power consumption and connection stability for long-running IoT devices - Deliver clean, well-documented, production-ready code Hardware - Design or refine schematics and PCB layouts - Review board revisions when adding new sensors or modules - Ensure designs are DFM-ready for manufacturing - Support testing, bring-up, and debugging I’m very comfortable working in iterative development cycles, maintaining clear documentation and changelogs, and collaborating via Git and periodic calls so the project can evolve smoothly over time.
