Embedded Firmware Development (ESP32 & Arduino)

Firmware is where the physical world meets your software. I write firmware for ESP-based and Arduino devices — reading sensors reliably, connecting to your backend and updating devices remotely.

  • Arduino
  • Embedded C
  • C
  • Sensors
  • OTA
  • MQTT

What I can help with

ESP32 / Arduino firmware — what's included

  • 01

    ESP32 firmware

    Firmware for ESP-based devices, from first prototype onwards.

  • 02

    Sensor integration

    Reading and handling sensor data on the device.

  • 03

    OTA updates

    Updating firmware over the air, so devices don't need physical access.

  • 04

    Backend connectivity

    Sending device data to your APIs or cloud.

  • 05

    Arduino prototyping

    Quick hardware prototypes to prove an idea.

  • 06

    Device debugging

    Finding out why a device misbehaves in the field.

Relevant experience

Built on real work

  • ESP-based firmware & OTA

    IST Technologies

    Firmware for environmental monitoring devices, including over-the-air updates.

  • Disha Autonomous Robot

    Project

    Autonomous robot combining AI with Arduino-based hardware.

  • 1st Place — Hardware Hackathon

    UPES, 2022

    First place at a hardware hackathon.

A good fit if…

  • You need firmware for an ESP32 or Arduino-based device
  • Your devices need remote updates
  • You want firmware written by someone who also understands the backend it talks to

How we'll work

A clear process, even when the problem isn't

I don't need to know everything before I start — I need to know how to figure it out.

  1. 01

    Understand

    Break down the problem and understand the system.

  2. 02

    Explore

    Research technologies and possible approaches.

  3. 03

    Build

    Create a practical working implementation.

  4. 04

    Debug

    Find bottlenecks, failures, and edge cases.

  5. 05

    Improve

    Optimize performance, reliability, scalability, and usability.

  6. 06

    Ship

    Deploy, monitor, support, and iterate.
