Building quantum algorithms and AI systems across optimization, simulation, scientific discovery, agents, and language-model workflows — from Shor's algorithm and quantum differential-equation solvers to hybrid quantum–classical software.
I am a Research Engineer at Singapore Management University working across quantum computing, quantum algorithms, and AI. My work spans hybrid quantum-classical optimization, Shor-style factoring experiments, quantum simulation and differential-equation solvers, LLM-guided research loops, AI agents, and scientific software systems.
I worked on MettleQ, a trustworthy local quantum-circuit simulation package for Apple Silicon. It integrates with Qiskit and PennyLane, exposes exact statevector and matrix-product-state simulation paths, and uses MLX/Metal execution with measured dispatch policies and reproducible benchmark evidence.
Ratio above 1.0x means MettleQ GPU was faster. In this latest run, MettleQ crosses PennyLane Lightning at 16 qubits and Qiskit Aer at 20 qubits.
| Qubits | Qiskit CPU/GPU | PennyLane CPU/GPU |
|---|---|---|
| 20 | 1.327x | 11.097x |
| 24 | 4.554x | 18.713x |
| 29 | 2.739x | 16.005x |
I also built The Atelier Lab, a local AI research laboratory for reproducing modern AI systems from first principles. It combines a foundation-model track with an autonomous local agent that runs on a single MacBook using Ollama, local embeddings, RAG, durable memory, and test-verified build mode.
Baseline training measurements on an Apple M3 Pro, alongside a local agent stack for RAG, memory, code repair, and test-verified edits.

| 286.2M | ~4.47k tok/s | ~5.1 h | 1.0954 BPB |
