I am a passionate and detail-oriented Computer Engineer with a specialization in Data Engineering with a strong foundation in data pipelines, ETL processes, data solutions. What drives me most is my constant curiosity and enthusiasm for learning the latest tools and technologies in data engineering.

Beyond technical skills, I am a collaborative team player who values clean, maintainable code and data best practices.

I’ve been part of different project while being a Data Engineer, during my employments I worked on the following projects:

I developed and maintained desktop applications using ASP.NET and C# to efficiently manage and update English students' records for the academic department. Additionally, I designed and implemented a comprehensive library management system.

Designed and implemented a robust MySQL database to streamline operations for a Korean skincare e-commerce platform. The system:

· Automated client & product registration, reducing manual entry errors.

· Simplified order processing & sales tracking, enabling real-time revenue analytics.

· Enforced role-based access control (RBAC) with three secure user tiers (Clients, Sellers, Administrators), improving data security.

Applied normalization (3NF) to eliminate redundancy and ensure data integrity.

Designed an intuitive ER model for scalable product/customer relationship management.
