Hello, I understand you’re looking for an experienced Backend Developer to build a reliable API-driven payment automation system that streamlines billing, reconciliation, and internal data synchronization. I have strong hands-on experience designing secure, scalable payment workflows that automate transaction triggers, handle real-time status updates, and ensure accurate reconciliation across databases. My approach focuses on clean REST API architecture, fault-tolerant processing, and clear separation of services to ensure long-term maintainability. I work confidently with JavaScript and Python-based backends using Node.js, PostgreSQL, and MongoDB, and I routinely containerize services with Docker for consistent deployment across environments. Payment events are handled with robust validation, logging, and retry mechanisms to prevent data mismatches and failed updates. I also ensure seamless integration with frontend layers such as AngularJS for visibility into payment states when required. Security, performance, and data integrity remain central throughout development, resulting in an automated billing workflow that reduces manual effort and operational risk. Thanks, Asif
