I’d like to work on this issue because I’m a backend developer experienced with NestJS, TypeORM, and PostgreSQL, and I’ve built workflow-driven modules with state machines, audit trails, and multi-level approval systems. I’m comfortable implementing bulk operations, notifications via email/push (using tools like Nodemailer), job queues with Bull, and SLA tracking, ensuring correctness and performance. I also focus on writing comprehensive unit tests and clear API documentation, making me well-suited to deliver a robust document verification workflow module.
