What I'm looking for

I seek a role focused on scalable ETL and data platform engineering where I can improve performance, automate pipelines, mentor teams, and work in an agile, collaborative environment with opportunities for technical growth.

I am a results-oriented Data Engineering professional with over 3 years designing, developing, and supporting enterprise-grade ETL processes, data warehousing solutions, and distributed big data systems. I combine hands-on engineering with a focus on reliability and data integrity.

I have led high-impact projects including Oracle migrations, revenue analytics platforms, and automated data-quality monitoring systems that improved performance and availability. I routinely implement scalable ETL pipelines with Informatica PowerCenter, Apache NiFi, and Hadoop ecosystem tools.

My strengths include SQL and query optimization, Oracle database administration and tuning, automation with UNIX shell scripting and Python, and building BI solutions with Qlik Sense and Power BI. I have a track record of reducing query times, improving system performance, and creating self-healing monitoring for critical pipelines.

I am committed to continuous learning and knowledge sharing, holding certifications such as Oracle Certified Professional and Google Cloud Data Engineer, and I mentor junior engineers while collaborating across technical teams to ensure smooth migrations and platform upgrades.
