Nguyen ThiNguyet Que
Backend Software Engineer
I build backend for enterprise systems where APIs, data, permissions, and workflows need to be clear, reliable, and easy to operate.

01 / About
Backend-focused, practical, and maintainable
I work on backend systems for enterprise workflows: APIs, permissions, reporting, approval flows, and the data models behind them.
What I enjoy most is making complex operations easier to follow: clear APIs, predictable permissions, structured data, and workflows that teams can trust.
At the moment, I am growing toward enterprise backend engineering, reusable backend foundations, and practical AI-assisted automation.

2024 - 2025
Backend-focused Full-stack Developer
Built and maintained backend workflows for ERP modules such as document management, warehouse, assets, payroll, tax, reporting, and approval processes. This work shaped how I think about data integrity and daily business operations.

04 / Notes
Technical notes
A few things I keep learning while building backend systems in real workflows.
APIs should be predictable
Good API behavior is easy to explain, easy to test, and consistent enough that another engineer can extend it without guessing.
AI belongs inside workflows
Model calls are only one part of the system. Validation, fallback, review, logs, and cost control decide whether the feature is usable.
Documentation is operational care
Useful notes do not need to be long. They should preserve decisions, setup steps, contracts, and the sharp edges future maintainers should know.
05 / Research
Research & beyond coding
Ontology / RAG
I am exploring how knowledge modeling, retrieval, and LLMs can support answers with clearer context and more explainable structure.
Technical documentation
I treat documentation as part of operations: preserving decisions, setup, contracts, and the edges future maintainers should know.

I am interested in backend engineering work around reliable APIs, enterprise workflows, and systems that stay useful in daily operations. If my direction feels relevant to your team, I would be happy to connect.
