Hello, I am

PHP / Backend Developer

Currently at NTQ Solution, working with PHP (Laravel, CakePHP) and SQL. I have upgraded a CakePHP 2.x system to 5.x, built email automation with Laravel queues and the scheduler, and synced PLC data into SQL Server.

About

I studied Information Systems at Thuy Loi University and have spent 2+ years working on backend development. My experience ranges from a factory production system (SIFMES) to a CakePHP legacy upgrade, and I currently work as a Backend Developer at NTQ Solution.

I enjoy upgrading old systems safely, building background jobs that can retry and be monitored, and keeping data in sync between systems.

Capabilities

01

Legacy migration & Regression risk

  • Hands-on experience migrating legacy CakePHP 2.x systems to 5.x.
  • Analyzed impact scopes and resolved old logic bugs to mitigate regression risks.
  • Ensured compatibility for core business flows post-migration.
02

Backend operations & Automation

  • Developed Laravel scheduled jobs and queue workers for email automation.
  • Managed job states, implemented retry mechanisms, and detailed logging.
  • Built stable operational flows that are easy to monitor in production.
03

API, Database & Data sync

  • Designed REST APIs and built data synchronization flows between systems (e.g., PLC to SQL Server).
  • Applied database locks, retries, and logging to protect data integrity.
  • Proficient in SQL queries, schema analysis, and handling data constraints.
