I will build esp32 firmware and a mobile app for your iot project

You need ESP32 firmware. You also need an Android

app. Normally that means hiring two freelancers

and a week of integration headaches.

I build both. One developer, one codebase, designed

together from the start.

BASIC ($35) Connect

ESP32 firmware over BLE or Wi-Fi

Android app: live data display or device control

Full source code + wiring guide | 5 days

STANDARD ($70) Monitor & Control

Up to 6 sensors + Android app with live UI,

control buttons, clean layout

Commented code both sides + docs | 7 days

PREMIUM ($120) Full System

Multi-sensor ESP32 with FreeRTOS + threshold alerts

Multi-screen Android app: dashboard, controls,

notifications, error handling

Wi-Fi/MQTT or BLE | Full documentation | 10 days

When one person builds both sides, integration

problems don't exist. I design the protocol, the

data structure, and the UI together.

I built a 12-sensor industrial monitoring system on ESP32-S3 with FreeRTOS and safety logic. My first client was so satisfied with the quality that he pushed me to start freelancing. That reaction is what convinced me I could deliver at a professional level so here I am.

Message me with your project details I'll confirm scope and timeline.
