About

INTRO.TXT

I grew up in Jing'an, downtown Shanghai, and used to spend weekends at my family's seaweed factory, watching machines process seaweed down the production line and margins get debated during family dinners. CS wasn't really on my radar until I took Fundies I, Northeastern's intro course. Turns out I love it.

I've carried a CS and Finance double major workload, minus supply chain, which never clicked for me. Inside school, I TA Khoury's DS course; outside, I've interned at Johnson & Johnson MedTech in orthopedics and at Advent International, a global private-equity firm.

I'm currently exploring Spring 2027 full-time roles in software engineering. Feel free to browse my site, and I'm always happy to chat if anything sparks your interest. :D

ABOUT_ME.TXT

A Bit More About Me

  • For over two years, I've helped fellow international students adjust to life in Boston as a Global Student Ambassador with NU's Global Pathway Program.
  • Outside of school, I like exercising, grabbing coffee and chatting with friends, and digging through GitHub for interesting open-source projects.

What I'm Looking For

I'm actively seeking full-time roles starting Spring 2027 in software engineering. I'm based in Boston but open to relocation, and I'm authorized to work in the U.S. without sponsorship now or in the future.

Experience

Northeastern University — Khoury College - TA, Foundations of Data Science (DS3000)

-

Teaching assistant for a required Data Science concentration course in Khoury's accelerated Summer 2 format, supporting 60+ students through Python-based data analysis, NumPy, pandas, classification/regression, and KNN.

  • Graded weekly quizzes and provided detailed feedback to reinforce student understanding of pandas, NumPy, data cleaning, and intro ML.
  • Ran weekly office hours, clarifying course concepts and collaborating with fellow TAs to improve student learning.

Johnson & Johnson MedTech - Orthopedics Offer Development (OOD) Analyst Intern

-

Worked on the DePuy Synthes orthopedics business in Raynham, MA — a mix of contract analytics, Python automation, and business-strategy deliverables.

  • Built a Python automation pipeline that batch-processed ~1,200 customer directories and used pattern matching to retrieve Requests for Proposals, reducing quote preparation time by 30%.
  • Engineered an Excel ETL pipeline consolidating 4+ disparate workbooks into a 4M+ data-point master and automating leadership reorg updates.
  • Developed an Excel dashboard comparing price erosion to sales growth on key DePuy platforms to drive margin-recovery insights.
  • Analyzed J&J's customer hierarchy and contract strategies across 10+ parent and 50+ standalone DePuy Synthes contracts to reconcile billing and ensure invoicing accuracy.
  • Led creation of an ~80-page Ethicon business overview deck across all key surgical platforms, coordinating marketing-partner interviews to accelerate new-hire ramp-up.

Advent International - Deal Cost Operations Intern

-

Supported the Deal Cost team at a global private-equity firm with recurring and ad-hoc operations, audit prep, and reporting.

  • Ran CRM deal status and deal-cost reports, processed vouchers/invoices, prepared 200+ monthly cash entries, and recorded $300k+ in check deposits.
  • Streamlined audit prep by organizing 200+ bank statements, reconciling 20+ accounts, and cleaning up $10k in deal costs.
  • Partnered with senior leadership in weekly team and monthly corporate meetings to review monthly close items and improve the finance pipeline.

Northeastern University — NU Global Pathway Program - Global Student Ambassador

-

  • Helped 200+ international students adjust to Northeastern through personal and career guidance.
  • Collaborated with 30 GSAs to organize semester events including orientation, cultural excursions, academic sessions, and co-op panels.

Modeling Persuasion on Reddit with NLP

In progress · Natural Language Processing

Currently working on this: a natural language processing project on what makes an argument persuasive online. Compares a statistical model (TF-IDF with logistic regression), a neural model (BiLSTM), and a pretrained transformer (RoBERTa) on about 41,000 pairs of Reddit comments, and tests whether each model learns argument quality or shortcuts like comment length.

Exoplanet Classifier

Exoplanet Classifier

NASA Kepler dataset · Gradient Boosting · PyTorch RNNs

Built an end-to-end ML pipeline classifying 6,640 NASA Kepler light curves using from-scratch Gradient Boosting and PyTorch RNNs, achieving 0.969 ROC-AUC, evaluated with cross-validation and ROC-AUC comparison across models. Constructed scalable pipelines for feature extraction and candidate generation, improved RNN performance through preprocessing and hyperparameter tuning, and developed evaluation visualizations to compare model performance.

React · TypeScript · Socket.io · Supabase

Designed full-stack Cribbage (Node/TypeScript, Supabase, Socket.io, React) with a configurable AI opponent, backed by a GitHub Actions CI/CD pipeline (ESLint, Prettier, Vitest, Playwright) and ~95% branch coverage. Engineered the React UI to WCAG standards with keyboard-navigable card selection, ARIA live regions for score updates, and screen-reader-friendly card labels.

Sanguine — Strategy Card Game

Sanguine — Strategy Card Game

Java · MVC · heuristic AI

A configurable two-player strategy card game inspired by Queen's Blood, built in Java over a ~6-week multi-phase semester project. Implemented board-state updates, scoring, turn-based gameplay, and file-driven deck management. Designed with MVC and interface-based abstractions for modularity, plus heuristic-driven AI players for card placement and row-score optimization.

C · fork/exec · pipes · I/O redirection

Built a Unix shell from scratch in C with command parsing, process creation (fork/exec), I/O redirection, pipes, sequential execution, and built-in commands (cd, source, prev, help). Implemented using low-level system calls and validated with Valgrind for memory management.

FPGA · FSM · Single-Cycle RISC-V Processor

Two hardware projects: (1) a railroad crossing controller FSM on an FPGA with minimized state logic and alternating flashing signals driven by a counter-based timing circuit; (2) a compact single-cycle RISC-V processor with instruction fetch, decode, execute, and register writeback, validated against manually traced register results.
