Johnnie Tse

About Me.

Hello! I'm Johnnie. I'm a Computer Engineering student at Queen's University with a strong passion for scalable backends, Kubernetes ecosystems, modern high-performance web applications, and autonomous embedded systems (HPC & ROS2). I focus heavily on contributing to monumental open-source architectures while pushing modern scalable limits.

In web execution, I’m focused on engineering distributed robust full-stack applications leveraging architectures within React, Next.js, and Node.js. My experiences span through creating enterprise RAG models deploying containerized infrastructure with Docker and multi-host Azure Kubernetes clusters.

Beyond the web, I architect C++ automotive applications for autonomous embedded systems via Controller Area Networks (CAN) and ROS2, while co-heading the Queen's HPC organization dictating high-performance compute architecture methodologies (MPI, Thread Networking, OpenMP, GPU scaling) for global Student Cluster Competitions.

Experience

My professional journey engineering open-source architectures, robust scalable platforms, and advanced high-performance solutions.

vLLMRemote

  • Open-source development for llm-d, a Kubernetes-native LLM serving framework, focusing on sustainable and carbon-aware AI infrastructure. Designed and engineered an Energy-Aware Endpoint Picker Plugin (EPP) to optimize token-level routing across heterogeneous hardware accelerators (e.g., H100s, L4s).
  • Architected a Multi-Objective Routing Engine: Developed a high-performance Kubernetes Gateway API Inference Extension (GIE) sidecar in Go (v1.25), introducing a strict epsilon-constraint routing pipeline that optimizes for energy and carbon efficiency while strictly enforcing TTFT and TPOT latency SLOs.
  • Phase-Aware Disaggregated Serving: Designed dynamic scoring models that differentiate between compute-bound prefill phases and memory-bound decode phases, actively routing requests to the most thermodynamically efficient nodes while calculating network KV-cache transfer penalties.
  • Carbon-Aware Controller: Implemented real-time dynamic weight modulation based on grid carbon intensity (SCI standards) and cluster thermal budgets, enabling micro-spatial workload shifting during carbon spikes.
  • High-Performance Go Engineering: Built a highly concurrent, thread-safe asynchronous eBPF telemetry ingestion plane using DCGM and RAPL metrics and Welford’s Algorithm for ms-precision signal filtering. Containerized the microservice into an ultra-minimal 8.6 MB distroless image with a negligible 101 microseconds routing overhead.
  • Kubernetes CRD Reconciliation: Designed a native client-go Informer architecture to actively reconcile InferenceObjective CRDs, allowing cluster admins to dynamically pivot between autonomous “Carbon-Critical” and “Load-Shedding” control states.
  • Quantifiable Impact: Achieved an average 17.4% reduction in LLM inference energy consumption (up to 32.3% for decode-heavy workloads) compared to standard round-robin scheduling, driving significant reductions in Scope 2 and Scope 3 data center emissions.
