ESP32 + firmware + mobile application (Android / iOS)

Thank you for the detailed description — this is no longer just an "application," but a full-fledged IoT system: hardware + firmware + mobile + preparation for mass production.

To be honest: the biggest risk in such projects is not the individual ESP32 or mobile application, but the integration of all parts into one stable system (Wi-Fi stability, protocol, OTA, power consumption, edge cases in firmware).

I am the CEO of Mobiwolf. Our key expertise is in the mobile part (iOS/Android/Flutter), and here we can cover the full cycle for you:
• mobile application (iOS + Android)
• UX/UI
• integration with the device (BLE / Wi-Fi / API)
• device management logic
…
Regarding hardware / ESP32 / PCB / firmware — this is also within the scope of such a product, but it is not our narrow specialization. At the same time, we work with proven embedded/PCB specialists and can:
• assemble a complete turnkey team for you
• take on the coordination between the mobile and hardware parts
• ensure that the API / protocol / firmware and application are aligned from the very beginning

So you are not looking for 3–4 different contractors separately — you are working with one responsible entity.

How we would approach the project:
• define the system architecture (device ↔ cloud ↔ mobile)
• establish the communication protocol (Wi-Fi API / MQTT / REST — depending on the scenario)
• simultaneously develop the firmware and mobile application
• lay the groundwork for OTA and scaling for mass production
• test stability in real conditions

Honestly about the start: we will be able to fully engage in the project in about 3 weeks, but we can already help with architecture and risk assessment.

To assess more accurately:
• does the device work only via Wi-Fi or is Bluetooth needed as well?
• are there already selected components or is this from scratch?
• how many types of devices are planned (one or a line)?
• is a cloud needed between the device and the mobile application?
• what is the management scenario: local or remote via the internet?

Next step:
we will move to a private chat — you will briefly describe the use case of the device, and I will suggest the optimal system architecture and how to best divide the work between hardware, firmware, and mobile to avoid costly reworks.

Details about the team, roles, and rates will be discussed there.

Best regards,
Oleksiy Karaykoza
CEO, Mobiwolf

Good day.
20 years of development experience, including:
- assembly of Arduino/ESP32 hardware, sensors, various circuits
- development of software for hardware, various sensors
- development of WEB applications CRM/ERP, integration via API with services
- development for Windows
- development of mobile applications
Therefore, I will do everything qualitatively and turn-key. I am very interested in the task.
I just finished a similar automation for a furniture warehouse ESP32 + sensors + Google Sheets + integration with CRM + Windows program.
…
Please clarify the purpose of the device, what it will be used for.
Then I will be able to propose the architecture of the hardware and software part as a whole.
Considering the overall picture, I can more accurately advise on power supply, controllers, compatibility, and optimized use of battery and resources, so that it works quickly and the devices are responsive.

Good day! I have reviewed your technical specifications. I have experience in developing devices based on ESP32 (specifically using I2S, LoRa, Wi-Fi/BLE). We can discuss the budget and make the shortest deadlines if possible.
