I'm interested in how data supports day-to-day business decisions, especially in payments and financial operations. I'm looking for full-time analyst and operations roles in Singapore.

Selected projects

Project What it does
Payment Reconciliation Compares ledger, payment processor and bank records; tracks differences and produces daily reports.
Revenue & Commission Calculates commissions from cash receipts, handles shared deals and refunds, and preserves closed-month statements.
Merchant Onboarding Follows an application through a policy change, requests missing documents and checks that approval uses the current version.
Ecommerce Analytics Explores orders, delivery performance, lead scoring and advertising experiments in an offline dashboard.
Ad Ops Approval Workflow Pauses generated proposals for human approval and handles duplicate requests and interrupted runs using a simulated action ledger.

Each project includes screenshots, a short walkthrough and setup instructions. These are independent projects; the repositories describe their datasets, assumptions and testing.

Tools used: SQL, Python, SQLite, DuckDB, dbt, Flask, FastAPI, LangGraph and React.
