Engineering Case Studies
Real-world projects with quantified outcomes across PCB design, firmware, Edge AI, AOSP, and mobile app development.
Low-Power Industrial Environmental Sensor Ecosystem
High unit production cost, poor battery life under sub-zero conditions, and frequent manufacturing yields failures on previous generation boards.
Designed a modular multi-layer PCB, integrated low-leakage power gating circuitry, and built a custom FreeRTOS power-optimized driver architecture with secure BLE 5.2 provisioning.
Edge AI Quality Inspection Camera Platform
High latency and heavy bandwidth consumption sending high-resolution video streams to cloud servers for defect detection in manufacturing assembly lines.
Engineered an edge vision device using NXP i.MX8M Plus with integrated NPU, running quantized INT8 MobileNet models on-device with sub-10ms inference time.
Ruggedized Industrial Field Tablet AOSP Platform
Commercial Android tablets lacked physical connector pinouts, suffered thermal throttling in direct sunlight, and could not be locked down securely for enterprise field technicians.
Developed a custom AOSP Android 13 platform for custom RK3588 tablet hardware, custom kernel drivers for RS485/CAN interfaces, and kiosk lockdown policies.
Portable Patient Monitoring Companion Ecosystem
Legacy medical monitors required complex manual data offloading via physical cables, causing workflow friction for hospital clinical staff.
Built a secure BLE gateway architecture inside the device firmware paired with native iOS and Android medical companion apps with real-time encrypted telemetry syncing.
