Welcome to my workspace โ where AI systems, game engines, and data-driven design come together.
Iโm a Masterโs 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, Iโve transitioned fully into software and AI engineering, building projects that bridge research and real-world implementation.
My current interests lie at the intersection of:
- ๐ง AI-powered systems โ Retrieval-Augmented Generation (RAG), Reinforcement Learning, and intelligent interfaces
- ๐ฎ System-level development โ modular C++/SDL3 engines, ECS architectures, and real-time rendering
- ๐ Optimization & data reasoning โ using embeddings, geospatial features, and ML pipelines to drive decision-making
-
๐ง OnCallGuide.ai
AI-powered emergency support system integrating RAG, multi-query expansion, and hybrid retrieval for high-precision decision assistance. -
๐ Optimization Framework for Large-Scale Detection Nodes
Multi-objective RL framework that optimizes sensor deployment based on geospatial risk heatmaps and connectivity constraints. -
๐ฎ 2D Game Engine (C++/SDL3)
Modular ECS architecture with custom event and rendering systems, serving as a sandbox for AI-driven gameplay prototyping.
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
