Software Engineer · Systems & ML · UBC VEMS

I build backend systems, ML pipelines, and interactive XR applications that are designed to work under real-world constraints.

My work focuses on:

• Distributed systems & backend architecture
• Applied machine learning (vision + NLP)
• XR/AR interaction systems

I care about latency, reliability, and correctness over flashy demos.

🔹 Exam Generation & Analysis System (Backend Lead)

• Built a microservice-based backend (Node.js, tRPC, Prisma, PostgreSQL)
• Processes 1000+ student submissions per exam cycle with automated grading
• Designed snapshot-based grading system for reproducibility and auditability
• Implemented RBAC + PostgreSQL RLS for multi-tenant security
• Developed cheating detection and analytics pipelines

🔹 PillCare – Multi-Modal ML System

• Built a vision + OCR pipeline (MobileNetV2 + CRNN) for pill identification
• Designed modality fusion system to handle ambiguous inputs
• Integrated OpenFDA APIs for real-time drug metadata

🔹 Companion – LLM-Based Support System

• Designed a multi-stage LLM pipeline with routing, safety classification, and fallback logic
• Built a persistent memory system for context-aware multi-turn interactions
• Implemented risk-aware response handling for safe and reliable outputs

🔹 XR Systems @ UBC VEMS

• Built real-time distributed systems for multi-user scientific visualization
• Achieved <80 ms interaction latency using optimized WebSocket pipelines
• Developed systems used in live classroom environments (100+ users)

• Developer Behavior Analysis (GitHub Data)
  Analyzing commits, PRs, and reviews to study collaboration patterns and detect anomalies

• AR Interaction Research
  Exploring spatial anchoring and interaction stability in non-ideal real-world conditions

Languages: Java, Python, TypeScript, C#, SQL

Systems: Distributed Systems, Microservices, Data Pipelines
Data: PostgreSQL, ETL, Query Optimization
Tools: Docker, CI/CD, Linux, Git

Once spent an hour debugging a system issue that turned out to be a missing semicolon.
The system was fine. I was not.
