About

Professional summary

I am a backend developer and Computer Systems Engineering student focused on building reliable server-side applications with Node.js, TypeScript, and Express.js. I have practical experience designing REST APIs, authentication systems, database-backed services, and automated data pipelines.

I have built backend projects including an e-commerce API with 29 endpoints, an event registration system with 16 endpoints, and an automated Telegram job-alert platform. My work emphasizes modular architecture, MVC patterns, secure authentication, validation, and maintainable code.

I work with PostgreSQL, MongoDB, Redis, Sequelize ORM, and SQL to model and manage application data. I have implemented JWT authentication, refresh-token rotation, bcrypt password hashing, and Redis-backed scheduling and locking mechanisms.

I am experienced in improving application reliability and automation. In my AI Career Platform project, I implemented source aggregation, deduplication, AI and rule-based job scoring, failover handling, concurrency controls, automated testing, and CI/CD workflows.

I value clean code, debugging, version control, and continuous learning. Through backend training and more than 90 hours of algorithm and problem-solving practice, I have strengthened my ability to build and test practical backend systems.
