👤 About Me

I am a Computer Science student at Universiti Malaya who enjoys building systems at the intersection of AI, finance, and data engineering.

Instead of only building isolated apps, I am interested in designing workflows, infrastructure, and tools that help people:

  • reason better with data
  • automate repetitive work
  • make better financial and operational decisions
  • turn messy ideas into usable products

My work usually falls into four areas:

🤖 AI Agents

LLM workflows, RAG, MCP tools, orchestration, automation

📈 Finance Systems

Market data, backtesting, personal finance, investment research

🔧 Data Engineering

ETL pipelines, orchestration, data quality, cloud workflows

🚀 Product Prototypes

Hackathon MVPs, AI web apps, fintech tools, developer utilities


🎯 Current Focus

AreaWhat I am exploring
🤖 Agentic AILLM orchestration, MCP, Claude Code workflows, RAG, tool-calling agents
📊 Quant / FinanceAutonomous alpha discovery, backtesting, market data pipelines, investment decision support
🔩 Data EngineeringData pipelines, orchestration, CI/CD, data quality, warehouse automation
