Embedded Firmware Development - ESP32 - SIM800C - OCPP 1.6J | HTTP

Dear Client, I am excited to submit my proposal for the Embedded Firmware Development project utilizing ESP32, SIM800C, and OCPP 1.6J components for your smart metering system. With over 30 years of experience in electronics design, circuit design, and PCB design, I am confident in my ability to deliver high-quality work for your project. As an expert in embedded firmware development, I possess advanced knowledge of RISC CPU architecture and programming, which will enable me to effectively develop a robust firmware that meets the highest standards of reliability and performance. I have extensive experience working with GSM communications protocols and other protocols like Bluetooth and Wifi when necessary. I also have a strong understanding of OCPP and how it works, which will allow me to effectively facilitate communication between devices using a secure HTTP architecture. I have reviewed the project requirements and understand the need for a smart metering system that is both reliable and efficient. My proposed timeline for the project is [insert timeline]. I am flexible and open to discussing any changes or modifications to ensure that the project is completed successfully and on time. I look forward to the opportunity to work with you on this project. Please let me know if you have any questions or require additional information. Thank you for considering my proposal. Best Regards Hari Mohan

Hi, I'm actively working as an embedded systems developer. I have experience handling MCUs such as STM, nRF, ESP, DA, TX, Arduino, PIC. I Have used DCMI, SDIO, LTDC, FMC, DM2D and USB protocols on different STM32 families. Thanks to ESP I have acquired knowledge of HTTP, MQTT, AWS and JSON, also in the design of basic web pages with HTML CSS and JS. I have also managed devices with the BLE protocol, and I have created applications using the GAP and GATT abstraction layers. I have a great command of the C language, C++, and a great capacity to learn something new. if you want to work with me contact me.

I am an Electrical Engineer ? from well known University and I worked 2 years in Solar plates Company ( Radsole ) as Managing Director .

Dear sir, I gone through your requirement. I have 15 years of experience of embedded domain. I worked with Ocpp for ev station. Apart from that I have good experience in sim com, gsm and WiFi. Kindly let us discuss in more details. Looking for long term association. Thanks, Abhijeet

I have strong understanding of Semiconductors, Analogue and Digital Electronics, Data Structures, SCADA. Have strong practical understanding of C, C++, Embedded C & Java Programing. I have strong technical hands-on experience of working on various software tools like Eclipse, Turbo C, Visual Studio, Proteous, KEIL. My Previous Project Describe Below. Roles & Responsibilities  Design and implement the software for embedded devices and system, from creation toproduction and deployment.  Test and debug system software.  Monitor and maintain the system after development,  Improve system efficiency and stability after development.  Collaborate with customers to create systems based on their needs. Project Work on: Light & Motion Sensor for Doors. Description: A motion sensor light circuit is a circuit in which a light turns on when motion is detected. With a PIR motion sensor integrated with an Arduino, we can detect movement and program the Arduino to turn a light on for a certain period of time once this motion is detected.  Role & Responsibilities: Work as a Backend Developer, build embedded systems using C++ and Embedded C and test& debug the systems.  Technology Use: C++ and Embedded C, Visual Studio, Arduino, Keil Compiler, Proteous, Microcontroller.

Hello, I m embedded system software enginner on Automotive industry and Im working microcontrollers like ESP32,STM32 and another controllers. I can help you for esp32 projects . And previously , I m worked ESP32 and MQTT protocol.
