I will fix and customize esp32 firmware for your sensor project

Need a focused fix or small improvement to an existing ESP32 sensor project?

Through Leovanne, I work on practical firmware and connected-device prototypes.

The Basic package covers ONE agreed bug fix or small change in an existing Arduino or PlatformIO ESP32 project, on ONE board with up to ONE sensor/module. You receive updated source code, build notes and one revision within the agreed scope.

Message me before ordering with your exact board, framework, source code, wiring diagram, sensor model, error logs and expected behaviour. We will agree a reproducible test and confirm hardware availability first.

Hardware validation requires access to the matching equipment or your assistance running tests and sharing logs. Compilation alone does not confirm real-world operation.

New firmware from scratch, multiple devices, custom drivers, PCB design, mobile apps and production certification require separate scope. Hardware, shipping and paid services are excluded.

Please remove passwords and private keys from supplied files. Delivery starts once complete requirements and usable source are received.
