What I'm looking for

I am looking for a role that challenges me and allows for growth, ideally in a collaborative environment that values innovation and data-driven decision-making.

I am an experienced Data Engineer with over 10 years of expertise in architecting, developing, and maintaining robust data pipelines, data lakes, and warehouse solutions across cloud and hybrid environments. My skills encompass big data processing, ETL/ELT development, and real-time streaming, enabling me to deliver high-impact solutions that drive analytics, AI/ML, and business insights.

Throughout my career, I have successfully led projects that involve migrating legacy systems to modern architectures, designing real-time data ingestion frameworks, and implementing data quality checks. My collaborative approach has allowed me to work effectively with cross-functional teams, ensuring that the solutions I develop meet the needs of the business while adhering to best practices in data governance and security.

As a lifelong learner, I continuously seek to enhance my skills in the latest technologies and methodologies in data engineering. I am passionate about leveraging my expertise to contribute to innovative projects that harness the power of data to drive decision-making and business growth.
