๐Ÿ‘‹ Hi there, Iโ€™m Yifei Ma (Jeff)

Welcome to my workspace โ€” where AI systems, game engines, and data-driven design come together.


๐Ÿงญ About Me

Iโ€™m a Masterโ€™s student in Computer Science at Northeastern University (Vancouver) with a background in education and a growing focus on applied AI and systems engineering.

Before entering tech, I was a teacher โ€” which taught me the value of clarity, iteration, and communication.
Since 2022, Iโ€™ve transitioned fully into software and AI engineering, building projects that bridge research and real-world implementation.

My current interests lie at the intersection of:

  • ๐Ÿง  AI-powered systems โ€” Retrieval-Augmented Generation (RAG), Reinforcement Learning, and intelligent interfaces
  • ๐ŸŽฎ System-level development โ€” modular C++/SDL3 engines, ECS architectures, and real-time rendering
  • ๐Ÿ“Š Optimization & data reasoning โ€” using embeddings, geospatial features, and ML pipelines to drive decision-making

๐Ÿš€ Current Projects

  • ๐Ÿง  OnCallGuide.ai
    AI-powered emergency support system integrating RAG, multi-query expansion, and hybrid retrieval for high-precision decision assistance.

  • ๐ŸŒ Optimization Framework for Large-Scale Detection Nodes
    Multi-objective RL framework that optimizes sensor deployment based on geospatial risk heatmaps and connectivity constraints.

  • ๐ŸŽฎ 2D Game Engine (C++/SDL3)
    Modular ECS architecture with custom event and rendering systems, serving as a sandbox for AI-driven gameplay prototyping.


๐Ÿงฐ Tech Stack

Languages: C++, Python, Java, TypeScript, SQL
Frameworks & Tools: PyTorch, Scikit-learn, Gradio, SDL3, React, Docker, Git
Focus Areas: Reinforcement Learning, RAG Systems, Feature Engineering, Entity-Component-System Architecture


๐Ÿ“˜ Background

  • ๐ŸŽ“ M.S. in Computer Science, Northeastern University, Vancouver (2024โ€“2027)
  • ๐Ÿ’ป Web Development Diploma, BrainStation (2023)
  • ๐Ÿงช B.Sc. in Chemistry, University of Alberta (2020)
  • ๐Ÿง‘โ€๐Ÿซ Former Teaching Assistant, BrainStation โ€” mentored 60+ students in React and JavaScript, recognized for excellence in teaching

๐ŸŒ Connect


Iโ€™m passionate about building systems that learn, adapt, and inspire โ€” from intelligent tools to interactive worlds.
