About me

Chapter II · The statement

I'm a Computer Science Engineering student specializing in Data Engineering, Analytics and Full Stack Development— designing systems that turn raw data into meaningful insights, and building the applications that power them.

Through internships, freelance work and leadership roles, I've built ETL pipelines, analytics dashboards, backend services and modern web applications. My goal is to bridge software engineering and data: reliable systems that are scalable, maintainable and useful in the real world.

First understand the system. Then improve it.
