HELLO, I'M
Johnnie Tse.
I build exceptional digital experiences — mobile apps, modern web, and high-performance compute — for scalable, user-centric software.
Engineering Core Vectors
Bridging the architectural gap between embedded systems hardware limits and scalable full-stack multi-host orchestration.

Spatial Engineering Showroom
Interact in real-time with procedural WebGL architectures reflecting my background in Autonomy and Systems Engineering.
Level 4 Autonomous Systems
A procedural representation of a sensor-equipped L4 autonomous vehicle. Features computationally active LiDAR arrays, cybernetic chassis rendering, and dynamic emission sensors. Drag to continuously rotate and inspect.
Why this matters: This architecture directly reflects my hands-on professional background in robotics, engineering autonomous vehicle trajectory planners, integrating complex 3D LiDAR point-cloud algorithms, and designing highly concurrent sensor fusion pipelines mounted natively on isolated embedded Linux hardware.
A 3D Embedded Microcontroller
A photorealistic, spinning 3D model of an ESP32 / Raspberry Pi 5 logic board procedurally generated natively in WebGL using primitive mathematics to ensure 100% offline proxy immunity.
Why this matters: This mathematical CAD reconstruction explicitly showcases my extensive low-level systems background. I specialize in writing raw C/C++ firmware, architecting custom PCBs mapped with complex I2C/SPI arrays, and deploying strict Zephyr RTOS state machines onto highly constrained Edge IoT devices for real-time electrical telemetry.
miniMD Molecular Dynamics Simulation
A real-time native WebGL implementation of the Mantevo miniMD proxy application logic. It continuously computes $O(N^2)$ Lennard-Jones forces and mathematical Velocity Verlet bounds for 300 active particles within local RAM executing ~45,000 concurrent integration operations natively every 16ms!
Why this matters: This live computational grid is a direct visual proxy of my ELEC498 Capstone engineering project mapping MPI synchronizations. I completely architected a phase-aware DVFS with thermal throttling engine tracking the exact Communication Phases of the bare-metal miniMD application. By analyzing RAPL data and MPI wait times natively, my algorithm executes real-time DVFS actuations dynamically shifting processor voltage and core limits natively under heavy 128GB node payloads.
Global Engineering Footprint
