Over eight months, contributed to Automattic/wp-calypso by building and refining payment and billing features, including enabling PayPal and Razorpay integrations, introducing UPI and BLIK payment methods, and implementing per-jurisdiction tax breakdowns for receipts. Leveraged JavaScript, TypeScript, and React to extend data models, update UI components, and manage environment-specific configurations. Applied feature flag management and rigorous testing with Jest to ensure reliable rollouts and maintain compliance, such as clarifying EU regulatory requirements. Enhanced checkout resilience by retiring legacy payment methods, improving error handling, and maintaining Stripe SDK dependencies, resulting in broader payment options, improved transparency, and reduced operational risk.

Jun 1, 2026June 2026: Focused on checkout reliability, payment-method retirement hygiene, and developer experience. Delivered three priority items across Automattic/wp-calypso: (1) Checkout payment method retirement with UI/validation cleanup and comprehensive docs; (2) Partial checkout failure routing to a dedicated failed-purchases page with enhanced receipt data and tests; (3) Stripe SDK maintenance with upgrades to latest Stripe.js and React Stripe integrations. These efforts reduce payment-method risk, improve checkout resilience, and equip teams with clearer retirement guidance and richer failure data for troubleshooting. Key technical accomplishments include class-to-slug mappings and API-core type maintenance, optional include_failed_purchases parameter in the receipt API, TanStack Query-based data flows, and upgrades to Stripe integrations.
