IoT Systems Engineer &
Full-Stack Engineer

Designed and created a complete IoT solution consisting of 4 separate PCB assemblies to control 2 mains voltage high current relays (25A). The system allows users to trigger and schedule relay operations through an Android application.

This project involved full-stack development from hardware design to cloud infrastructure. I handled the complete product lifecycle from conception to production, with the first batch of 1000 units successfully manufactured.

The system uses Firebase as the communication bridge between devices and the mobile application, ensuring real-time synchronization and reliable operation. The firmware implements secure MQTT communication protocols for robust IoT connectivity.

The project required innovative design solutions due to volume restrictions, leading to a modular 4-PCB architecture that maximizes functionality while maintaining compact form factor.

Architected and developed a comprehensive all-in-one hospitality management platform that revolutionizes the guest experience from booking to checkout. The platform serves 100+ properties, reducing check-in time by 80% while increasing guest satisfaction scores and generating 35% more revenue through integrated local services.

Built as a complete digital ecosystem that eliminates traditional hospitality pain points through contactless check-in, digital key management, integrated concierge services, and automated guest communications. The platform handles everything from ID verification to local experience bookings.

Developed a comprehensive IoT platform for managing over 1000 waste collection devices across multiple locations. The system provides real-time monitoring, device configuration, and GPS-based visualization of waste collection operations.

Implemented a robust security architecture using JWT authentication for device authorization and created a complete web dashboard for fleet management. The platform significantly improved operational efficiency and provided valuable analytics for waste collection optimization.

The platform handles multiple communication protocols including WiFi, LoRaWAN, and NB-IoT, ensuring reliable connectivity across diverse deployment environments. Data optimization was achieved through binary C struct transmission, minimizing bandwidth usage while maintaining real-time responsiveness.

Designed specialized PCB solutions for custom 3D printer heads used in advanced material science applications. The project focuses on enabling precise cell structure printing for research and development in material engineering.

This cutting-edge project bridges the gap between electronics design and material science, requiring precise control systems and specialized heating elements to achieve the accuracy needed for cellular structure fabrication.

The PCB design incorporates advanced thermal management and precision control circuits to ensure consistent material deposition at the cellular level, pushing the boundaries of what's possible in 3D printing technology.
