To live is to experience, to do all that life has to offer, to be liberated and to be burdened, to take lift into the air and to sink beneath the sea.
I'm a recent CS graduate at CUHK who enjoys building agentic AI/ML systems and doing independent research. Currently building at AWS; before that J.P. Morgan, Foodpanda, and a game studio. The rest of the time, I write.
Where I've put the engineering to work — from big tech to a bank to a game studio.
Architected a high-scalability multi-agent framework using concurrent sub-agents to parallelize complex data extraction, automated reporting, and intelligent web-scraping workflows. Developing an automated autoresearch framework to streamline and scale quantitative research, and engineered custom automation tools via Model Context Protocol (MCP) servers, Amazon Q, and advanced tool-calling to build self-service data-mapping pipelines that remove manual spreadsheet bottlenecks. Built a self-improving meta-agent simulation testbed to benchmark prompt robustification and model accuracy under distribution shifts — and served as a technical representative presenting complex AI architectures to enterprise clients and executive stakeholders.
Built a multi-agent system with an LLM-powered natural language query interface for Portfolio Analytics, combining structured and unstructured data. Engineered real-time data pipelines with quant researchers and PMs, and delivered an internal framework for dynamic code generation and execution via agent graphs — adopted across the Asset Management LOB.
Built an ML-driven vendor churn model from high-dimensional data, and an end-to-end pipeline for embedding, storage, and mapping of 3M+ menu items across companies. Improved reliability of mission-critical data by 10% via snapshot models and data-integrity fixes.
Sole programmer on a Unity / C# game prototype — designed and built the core mechanics end to end, with a bot system, procedural map generation, and round-based card mechanics, working alongside level designers and artists.
Independent studies and university research — from evolutionary game dynamics to language models, taken from a question to a result.
An agent-based market where players exchange wealth through Rock–Paper–Scissors on an evolving social graph. Bayesian, Random, and Imitator strategies compete under endogenous trust, betrayal, and reputation gossip. Across 300-run batches I track inequality (Gini) and information collapse (Shannon entropy), and identify a betrayal-cascade threshold near 0.60 — the point where the social network fragments irreversibly and inequality locks in.
The network graph is not background context — it is the market itself. Destroy the trust topology and you destroy the economy.
Final-year project. Trained a query-classification model and an adaptive hybrid-retrieval mechanism that decides when a cached response can be safely reused — lifting cache hit rate by 43% and F1 by 10% over a dense-retrieval baseline.

Curriculum learning, focal loss, and dynamic thresholds lifted entity-recognition F1 from ~0.05 to 0.68. Built a timeline pipeline with cycle detection (Kahn's algorithm) and an interactive, draggable visualization.

Art, at its core, is the expression of oneself — tasted through a personal process of creation and consumption that others could never fully comprehend. The art of living, then, is the attempt to live life artistically: to conduct seemingly ordinary acts with compassion and overwhelming love.
