Nguyen Tan Khoi

Backend Developer

Hello, I'm Khoi, a final-year Software Engineering student at HUTECH University. Over the past few years, I’ve developed a strong interest in backend development, and I’m excited to grow my skills while contributing to real-world projects.

View Projects Download Résumé

I focus on backend development with Java & Spring Boot — building RESTful APIs, integrating authentication with JWT and OAuth2, documenting services with OpenAPI, and deploying applications with Docker and Render.

Recently at Aipower as a Developer Intern, I worked on a Java EE migration project — moving services from Oracle to PostgreSQL. My work included optimizing complex SQL queries, writing API test cases, and collaborating with DevOps to build internal testing tools.

I'm seeking an entry-level Software Engineer role where I can contribute to real product codebases, learn from senior developers, and ship reliable features.

Experience

May 2025 — Aug 2025

Developer Intern • Aipower

• Optimized complex SQL queries after migrating from Oracle to PostgreSQL, reducing API response time.
• Designed and executed manual API test cases in Postman, validating outputs with SQL queries.
• Improved system stability by resolving bugs with developers and leading regression testing.
• Enhanced testing efficiency by building internal tools (Excel-checker, SQL-query-binder) in collaboration with DevOps.
