Tengo un firmware para ESP32 escrito en C/C++ que ya funciona, pero requiere algunos retoques. Busco a alguien con probada experiencia en ESP32 y en programación C/C++ que pueda: • Revisar el código existente, localizar los puntos débiles y optimizar lo necesario. • Modificar las funciones de control que indicaré —son cambios pequeños pero precisos— sin alterar el resto de la lógica. • Incorporar los ajustes adicionales que entregaré al inicio y verificar, con pruebas reales sobre placa, que todo sigue estable. Entrego el proyecto actual y las instrucciones detalladas tan pronto comencemos. Es un trabajo sencillo, pensado para quien conozca bien el SDK de Espressif, FreeRTOS y el flujo de compilación con [login to view URL], por lo que espero una ejecución rápida y limpia. Al finalizar, solo necesito el código actualizado y un breve registro de los cambios y pruebas realizadas.

Soy Majeed, ingeniero embebido centrado en ESP32 con ESP-IDF y FreeRTOS. Desarrollé firmware de sensores a nube con MQTT, buffer offline y OTA para un cliente de logística con más de 200 dispositivos en campo; el punto débil eran llamadas bloqueantes dentro de una tarea, resuelto reordenando colas y ajustando tamaños de stack — exactamente el tipo de revisión que pide tu código. ¿Por qué yo? -> Guía de fabricación de PCB gratuita incluida, para cuando toque una nueva tirada. -> Laboratorio propio para validar cada cambio sobre hardware real, no solo en simulación. -> Registro de cambios y pruebas documentado archivo por archivo. -> Respuesta en menos de 5 minutos en horario laboral. -> Horario de trabajo alineado con tu zona horaria. -> 2 semanas de soporte gratuito tras la entrega. ¿Hablamos 15 minutos para revisar qué funciones vas a tocar y fijar el alcance antes de empezar?
