• Set up and maintained GCP projects: serverless functions on Cloud Run behind a Nest.js backend, a VPC for the PostgreSQL database, and the migration off Digital Ocean.
• Spearheaded full-stack payment apps in React and Next.js, integrating Stripe for fiat and Coinbase Commerce, Binance Pay and MoonPay for crypto, alongside a third-party ticketing platform.
• Extended the checkout to every edition of both events: SuperAI in Singapore and London, and TOKEN2049 in Singapore, Dubai and New York, each with its own currencies, pricing and ticket tiers.
• Grew crypto payment adoption by 5pp and checkout conversion by 10% through an Ops admin dashboard and A/B testing a revamped checkout flow.
• Migrated the crypto payments portal from PHP to TypeScript, adding stress tests for thousands of concurrent transactions and improving reconciliation accuracy during high-volume events.
• Ran CRO experiments via VWO, GTM and custom funnel metrics, and monitored transaction health with PostHog to iteratively lift site-wide conversion.
• Set up monitoring and alerting so the team caught issues before customers did: UptimeRobot on every checkout, PostHog funnels and session replays, and Slack integrations that post payment failures and order events to the ops channel.
• Engineered a distributed sensing network that models crowd density and movement flow, generating real-time heatmaps for venue monitoring.
• Built a peripheral management system for Razer at SuperAI NEXT Hackathon 2026 that tracked inventory and prevented equipment loss.
