01 / ABOUT

About Me

Passionate developer with a data-driven mindset

I'm a Full Stack Software Developer and Data Engineer with extensive experience building scalable, high-quality applications. I specialize in designing and implementing modern architectures using frameworks like React, Next.js, NestJS, Go, and Node.js.

Beyond writing code, I'm highly collaborative—regularly conducting code reviews, refactoring and optimizing existing codebases, and working closely with QA teams to identify vulnerabilities, enhance security, and elevate software quality.

As a Data Engineer, I design and build robust data pipelines, optimize ETL processes, and create data warehousing solutions that transform raw data into actionable business insights. I'm proficient in tools like Apache Spark, Airflow, and DBT.

I thrive in agile environments, ensuring fluid communication across teams and contributing to both technical excellence and project success.
