Claude CodeExperience
- Integrated Stripe payment gateway in Go, implementing transaction lifecycle operations including refunds and webhook-based payment status verification for reliable synchronization.
- Integrated Braintree (PayPal) payment gateway in Go, implementing full transaction lifecycle (refund, void, resync) and building a backend abstraction layer for enhanced logging and reliability.
- Designed and built a Node.js CLI-based hot-reload system using Commander.js, replacing UI-driven workflows and improving developer efficiency across 10–15 engineers.
- Implemented incremental compilation and file-level syncing with WebSocket-based real-time updates, reducing rebuild times and enabling low-latency development workflows.
- Developed and maintained SDKs and build systems using Webpack, Babel, and TypeScript, supporting 8–9 production client applications.
- Built a database-agnostic admin platform supporting MongoDB and MySQL with dynamic query execution and 50+ predefined operations.
- Containerized services using Docker and docker-compose, including embedding runtime binaries for isolated execution environments.
