AI Powered Smart Diffuser Embedded System

A premium smart diffuser that holds up to 5 interchangeable scent cartridges and can blend and dispense up to 25 fully customizable scent combinations. Designed for both personal and commercial spaces — from homes and offices to hotels and luxury environments — it delivers a personalized aroma experience unlike any standard diffuser on the market.

Users can switch scents by simply flipping their phone or waving their hand in front of the device. This gesture-based interaction was built into the embedded system using sensor logic programmed in C++ on the ESP32 — making the experience feel intuitive and futuristic without needing to open an app every time.

The diffuser responds to voice commands — allowing users to change scents, adjust intensity or activate specific modes entirely hands-free. Voice processing is handled through cloud AI, keeping the device lightweight while still delivering a responsive and seamless voice experience.

The cloud AI engine learns user preferences over time and proactively recommends scents based on time of day, mood patterns and usage history — curating a truly personalized aroma environment. This makes the diffuser not just a device but an intelligent scent companion that adapts to the user.

The entire embedded system was built on the ESP32 microcontroller and programmed in C++ — handling sensor logic for gesture detection, actuator management for cartridge dispensing, WiFi connectivity for cloud AI communication and Bluetooth for mobile app pairing. All of this runs reliably on a single embedded platform.

The device uses WiFi for cloud AI communication — sending usage data, receiving recommendations and processing voice commands — while Bluetooth handles local mobile app pairing for real-time control. Both protocols were implemented and managed simultaneously on the ESP32 without conflict.

Designed the advanced electronic circuits for the diffuser — including sensor interfacing, actuator drivers for the cartridge dispensing mechanism and power management circuitry. Each circuit was designed to be compact, efficient and reliable enough for a consumer-grade product.

While the mobile app was built by a dedicated team, contributed directly to the UI design and user flow — ensuring the app interface aligned with how the hardware actually behaves. This cross-functional contribution helped bridge the gap between hardware capability and software experience, resulting in a more coherent product.

Spearheaded the company's entire technological direction — overseeing Web, Mobile App and AI development teams. Responsible for setting engineering standards, reviewing technical decisions and ensuring all teams were aligned toward the product roadmap.

Led technical strategic planning and product development documentation — translating business goals from executive level into concrete, scalable technical solutions. Produced technical specs, architecture documents and development roadmaps used across all teams.

Mentored junior engineers and interns across both technical and professional development — building a stronger internal team capable of executing the company's ambitious product vision independently.
