Project details

This gig is for clients looking for a Embedded Firmware Developer expert on ESP32 series of SOCs to develop firmware using the framework of their choice (ESP-ADF, ESP-IDF, PLATFORM-IO etc). Embedded & IoT systems using wireless communication technologies like WiFi, BLE, ESP-NOW will be developed based on the client's choice and the system's stability, reliability will be ensured. OTA over BLE, WIFI is another set of special features this gig offers. Apart from network technologies, this gig covers embedded systems development using various wired communication protocols like I2C, SPI, UART etc, usage of ULP in the ESP32 series of SOCs and various other sleep-modes (light, deep sleeps) too to develop low-power consuming systems. The above system portrayed in the video is one such system that runs on ESP32 by using SPI, BLE comms with firmware developed using ESP-ADF. Looking forward to connect and build something nice.

Are you building an IoT product and need firmware that actually works in the field? I'm Lalith, an Embedded Firmware Engineer with 3+ years of hands-on experience delivering production-grade firmware for IoT devices.
I specialize in:

Microcontrollers: STM32, ESP32, ESP32-S2/S3, nRF5340, Raspberry Pi
Protocols: SPI, I2C, UART, BLE, MQTT, HTTP/HTTPS, USB, Ethernet
RTOS & Bare-Metal: FreeRTOS, Zephyr RTOS, DMA, OTA, Secure Boot
Tools: ESP-IDF, STM32CubeIDE, PlatformIO, Balena OS

I've worked across the full product lifecycle — from driver development and sensor integration to test firmware, production support, and OTA updates. My work at Alomind Labs and Adapt Ideations gave me deep experience building reliable IoT data loggers, and I currently deliver embedded products as a contractor at Spastha Dynamics.
On Upwork, I've built a strong track record with clients across the globe, consistently delivering quality firmware on time. If you need someone who understands both the hardware and the software side of embedded systems, let's talk.

Steps for completing your project

After purchasing the project, send requirements so Lalith can start the project.

Delivery time starts when Lalith receives requirements from you.

Lalith works on your project following the steps below.

Revisions may occur after the delivery date.

Overview of the application to be built

I will first pen-down the requirement of the project and will understand the big-picture. I usually make a flow about the approach to the project.

Implementing one thing at a time

The development flow that is penned-down will be followed. One at a time, each feature will be developed and will immediately be followed by testing.

Review the work, release payment, and leave feedback to Lalith.
