Experience
  • •Build and maintain PHP/Laravel backend services for the customer dashboard where clients manage their football data API subscriptions, in production with real customers. Develop core billing features: subscription plans, payments, invoicing and plan upgrades/downgrades, handling edge cases such as proration, failed payments and VAT. Design and implement RESTAPIs connecting the dashboard frontend with billing and account services (PostgreSQL). Work directly with frontend, product and support teams to scope requirements, ship features and follow up after release. Investigate customer-facing issues from the support team, tracing them through logs and data to the root cause. Use AI coding tools (Claude Code, Cursor) to speed up delivery, reviewing and testing all generated code before merging
