I manage a $1.2B payroll platform at Amazon across 6 APAC markets. At home I run a 50-service homelab and experiment with perfume.
by day
• $1.2B payroll platform across 6 APAC markets
• ISO 20022 payments, API/SFTP integrations
• Fraud detection on 1.5M transactions
by night
• 50 services on bare metal
• Self-hosted Matrix, AI inference, media stack
• Molecular perfumery experiments
Started at Amazon in customer service quality. The work was repetitive but the broken processes were everywhere, so I started automating them. Python scripts, SQL queries, VBA macros. Saved about 40 hours a week. Eventually owned quality strategy for operations handling 10M+ customer contacts a year.
Moved into leadership with the India background check revamp — cutting turnaround from four months to one. Grew a team from 10 to 45. Then into Global Payroll, where I define technical requirements for two engineering teams and manage a platform processing $1.2B annually across six markets.
