Zhoujing CHEN

First Moment, Shanghai

• Built a minute-level BTCUSDT perpetuals RL trading framework with separate train/validation and a strict out-of-sample holdout; evaluated under next-bar VWAP execution with realistic transaction costs.
• Designed a continuous-action policy with standardized time series features; mapped target position to fixed notional partial adjustments to cap turnover and suppress noise trades.
• Proposed a reduced-clip schedule for PPO with momentum-based pretraining; implemented baselines (DQN, DDPG, Bollinger, momentum) and observed superior risk-adjusted performance on the holdout.

Group R3 – CentraleSupélec, Gif-sur-Yvette

• Built a reproducible CPLEX/OPL environment and modeling guide; implemented a baseline intermodal MILP and a synchromodal extension where flexible services activate only after fixed capacity is saturated, to quantify resilience benefits.
• Extended the models to a time-expanded network with full cost accounting (timetables, handling/warehousing, carbon tax) and disruption-adjusted truck travel times, enabling rapid replanning under sudden outages.
• Prepared a scenario suite (baseline demand, capacity reductions, link outages—single-node to regional cascade) and compared integer-flow vs. relaxed formulations with abandonment penalties to assess trade-offs in solution quality and runtime.

Merit Interactive Co., Ltd., Hangzhou

• Developed and maintained large-scale backend and data processing services using Java, Spring Boot, Spark, Amazon S3, and ClickHouse on Kubernetes.
• Participated in the full SDLC from requirements analysis to deployment, delivering multiple feature iterations on schedule.
• Built and fixed RESTful APIs with clear controller and service layers; produced internal API documentation.
