About Olivier

I’m an electronic engineer and founder of Raspiaudio, a niche hardware brand that has shipped thousands of audio-centric boards and speakers for Raspberry Pi and ESP32 worldwide. I help companies turn rough ideas into production-ready devices that talk, listen, and learn—all in real time.

What I deliver

Edge AI & LLM integration – Deploy OpenAI, Google and open-source models directly on microcontrollers or stream them efficiently from the cloud, achieving sub-500 ms round-trip on an ESP32.

Embedded audio pipelines – Low-latency capture, TTS, A2DP and multi-channel I²S on custom PCBs; proven in my Muse Radio and Muse Luxe product lines.

Raspberry Pi expertise – HAT design, kernel drivers, and manufacturing know-how—right through to Amazon FBA logistics.

Real-time optimisation – DMA-driven audio, Wi-Fi/BLE coexistence, secure OTA, and tight power budgets for battery or solar use.

Cloud hooks – Firebase, Google Cloud IoT, REST/WebSockets analytics; your device never ships blind.

Typical engagements

Prototype in <4 weeks – Custom ESP32 firmware, 3D-printed enclosure, and a live cloud dashboard.

Cost-down redesign – Shrink BoM 20–40 % while adding OTA updates and usage metrics.

Rescue missions – Fix flaky Wi-Fi, audio pops, or factory-line DFU failures.

No fluff—just pragmatic engineering that ships. If you need hardware that processes audio, runs AI, and stays rock-solid in the field, let’s talk.
