Informazioni su questo servizio
TUV NORD certified embedded engineer. 8+ years programming microcontrollers for DRDO defence projects, Indian Railways, oil refineries, and medical devices.
I'm Parman Josan, R&D Head at Pelectro. I write firmware that runs in real products - not just on a breadboard.
What I code:
- ESP32 and Arduino firmware (WiFi, Bluetooth, IoT, cloud sync)
- PIC, 8051, and Nuvoton programming for industrial applications
- Sensor integration: I2C, SPI, UART, RS485, 4-20 mA, ADC
- Driver coding for displays, motors, RFID, relays, and actuators
- Mesh networking and frequency-hopping communication
- Low-power optimization for battery devices
Real projects: gas detection system with Zone-0 sensors, RFID boom barrier for 10,000+ users, 13mm wireless trigger with 250 microsecond latency, 2.4 GHz RF oscillator.
My firmware runs in trains, refineries, and defence systems. It works on the bench, not just in simulation.
Send me your project details, components, or just an idea. I'll review everything and give you an honest delivery plan before you order.

FAQ
Which microcontrollers do you program?
ESP32, Arduino (Uno, Nano, Mega), PIC, 8051, and Nuvoton. I also work with STM32 on request. Tell me your MCU and I'll confirm compatibility.
Can you also design the PCB for my firmware?
Yes. Check my PCB design gig on my profile. I can deliver firmware only, or firmware plus a complete PCB design. Ordering both from one seller saves you time and money.
Do you provide the source code?
Yes. Every package includes full source code with comments. You own the code and can modify it yourself after delivery.
Can you integrate WiFi, Bluetooth, or cloud services?
Yes. I work with ESP32 WiFi/Bluetooth, MQTT, HTTP, and Firebase. I can connect your device to a phone app or cloud dashboard. Order Premium for full IoT integration.
I don't know which components to use. Can you help?
Yes. Tell me what your device should do and I'll recommend the right microcontroller, sensors, and modules. I've selected components for defence and industrial projects for 8 years.
