B.Sc. in Computer Science; Minors in Data Analytics and Informatics, and Business

Final-year project (Prof. XU Hong): co-developed Bayesian scoring and conformal risk control for a 4B LLM; reduced tasks with rule violations by about 80% versus a prompted agent on a held-out synthetic tool-use testbed.

Relevant courses: Compiler Construction (A), Operating Systems, Algorithms, Data Structures, Computer Organization, Software Engineering, Formal Languages & Automata, Programming Languages, Probability, Statistics, Linear Algebra. Currently: Quantitative Methods for Financial Derivatives; Quantum Computer Systems (postgraduate).

Lead Developer, Quant Research Team, CUHK Quant Trading Society, Hong Kong

• As the team’s sole developer, architected its market-data platform: 700B+ stored A-share and crypto rows in the 2026-10-05 snapshot, not a unique-row count. The platform also supports Polymarket, outside that sum.
• Built its Python/HTTP/SQL query service with version-pinned reads and point-in-time checks. A separate 420,000-row concurrency fixture kept all 23 of 23 commits with 12 readers and 5 writers.
• Led implementation of the team’s data-quality work: duplicate cleanup and checks that prevent look-ahead leakage into research data.
• Built access controls in C, monitoring, alerts and operator documentation for shared research infrastructure.
• Built a Go HTTP/WebSocket relay with request validation, TLS termination and address scrubbing.
• Built guarded AI coding agents with recoverable deletion and approvals; tested the guard against independently identified bypass cases.

BRAIN Research Consultant (Gold level), WorldQuant, remote, part-time

• Researched and submitted 11 equity alphas in July 2025; the 5 October 2026 snapshot records a best individual out-of-sample Sharpe of 2.18 in BRAIN simulation.
• Built Python tooling that manages simulation runs (concurrency limits, checkpoint/resume).

STEAM Programming Tutor, Christian Alliance S. C. Chan Memorial College, part-time

• Taught programming and STEAM projects to 50+ students, designed curriculum materials and hands-on coding activities, and mentored student teams that won two programming awards.
• Also Head of Discipline & Tutor at Advanced Learning Centre (2023–).
