Ming-Tung H.

I work in backend teams building fulfillment and logistics systems that power end-to-end operational workflows, from order processing to delivery coordination.

My focus is on designing and implementing reliable backend services using Python, Flask, and SQLAlchemy, with an emphasis on data consistency, system simplicity, and maintainable service architecture.

I worked on a backend system to redistribute food oversupply using an AI-assisted matching approach aimed at reducing food waste and improving supply-chain efficiency.

Built with Python (Django), containerized using Docker, deployed on AWS, and automated via GitHub Actions, with a focus on reliable data pipelines and operational workflow automation.

I worked in the PayIn team, responsible for integrating multiple payment methods into a unified backend payment system.

Built using Python (Django, Flask) with Domain-Driven Design (DDD) principles, and containerized via Docker, the system focused on reliable payment processing, clean domain boundaries, and robust integration with external payment providers.
