Software engineer · CS '25 · open to roles

I'm a software engineer working across systems, machine learning, and interactive 3D. From real-time 3D pose-estimation research at Peking University to Dockerized monitoring stacks at REON and a Godot empathy game, I like building things that hold up under real use — tools, hardware, and experiences included.

About

I build across the full spectrum — backend systems and data pipelines, ML research, game development, and hardware. I turn ambiguous problems into shipped, dependable things.

At Peking University's HOME Lab I worked on real-time 3D human pose estimation, building validation methods that surfaced joint instabilities visual inspection missed. At REON I owned a data-validation layer and a Dockerized monitoring stack that stabilized nightly experiment runs.

Outside of work I model in Blender, build games in Godot, run a localization channel with 1M+ followers, and hold a design patent for an all-in-one keyboard computer. I care about accessibility, craft, and making complexity feel simple.

Based in Waltham, MA, USA.

Experience

Research Assistant, Real-Time 3D Human Pose EstimationPeking University — HOME Lab

Jun 2025 — Dec 2025 · Beijing, China

Contributed to sparse-sensor-based 3D motion reconstruction research for real-time human pose estimation.

  • Implemented calibration procedures and keypoint integration for real-time pose-estimation pipelines
  • Developed validation methods tracing intermediate results — monitoring joint stability, temporal consistency, and latency
  • Identified reconstruction instabilities that surface-level visual inspection missed
  • Tested hypotheses around calibration accuracy, confidence thresholding, and temporal smoothing strategies
  • Connected technical decisions to downstream HCI applications — sensor placement and motion representations for natural virtual character interaction

Software Engineer InternREON Technology Inc.

Jun 2023 — Jan 2024 · Chelmsford, MA, USA

Built the data-validation layer and observability stack behind BMS battery experiment analysis.

  • Designed a lightweight data-validation layer (schema checks, timestamp alignment, unit normalization) shifting analysis from manual clean-up to first-pass trustable datasets
  • Orchestrated Dockerized services for the monitoring stack and added observability hooks (structured logs, health probes) — stabilizing nightly runs and enabling one-command deployments
  • Built decision-ready Jupyter dashboards translating raw cycles into SoC/SoH and event views used in weekly stakeholder reviews
  • Sped up reviews, reduced re-runs, and helped stakeholders triage anomalies earlier

Channel Operator, Translator & ProofreaderDIY Perks (Authorized Bilibili Channel)

Nov 2020 — Present · Online

Led a 7-member team localizing creator content across Chinese platforms — 160+ videos, 250M+ views, 1M+ followers.

  • Led a 7-member team localizing and publishing creator content across Bilibili / Tencent / Baidu / Xigua, standardizing translation and QA workflows
  • Shipped 160+ translated/proofread videos with 250M cumulative views; grew to 1M+ followers within the first month of launch
  • Negotiated 6 brand partnerships (Royole, Flexispot, Influcity) generating $25,000+ in sponsorship revenue
  • Built Python + Excel automation for payouts and tax tracking — cut monthly accounting from 8 hours to 1 hour and improved payout accuracy

Teaching Assistant — COSI 150A: Compiler DesignBrandeis University

Jan 2024 — May 2024 · Waltham, MA, USA

Held office hours, graded, and co-developed course materials for the upper-level compilers course.

  • Held weekly office hours assisting 20+ students with lexical analysis, parsing, code generation, and optimization
  • Graded exams and assignments with detailed feedback reinforcing compiler theory and implementation
  • Collaborated with the professor to prepare lecture materials, problem sets, and exam questions

Projects

Self-Hosted AI Chat

Ongoing · LLM · InfraQwen LLMs on my own GPUs

Self-hosted LLM chat platform running Qwen models on a home RTX 3090Ti rig — Dockerized model serving, inference, and a web UI. Why pay OpenAI when you can pay the electricity bill instead? (Spent more on power than API calls would've cost, but learned a ton about LLM deployment.)

Built with: LLM, Docker, DevOps, Python.

CS Robot Competition

Side project · Robotics2v2 real-robot Counter-Strike

2v2 real-robot Counter-Strike — because regular programming wasn't complicated enough. Computer vision for target detection, pathfinding algorithms, and multi-robot networking. Current status: robots can see each other, sometimes they even move.

Built with: Robotics, Computer Vision, Pathfinding, Networking.
