What I'm looking for

I seek a role that fosters innovation and allows me to leverage my data engineering skills in a collaborative environment.

I am a Data Engineer with over three years of experience in optimizing data processes within high-demand environments. My expertise lies in enhancing data pipeline performance, reducing operational costs, and ensuring seamless integration using cutting-edge technologies such as Apache Airflow, Databricks, and Spark. I have achieved significant results in automating workflows, notably increasing processing efficiency by 30% and reducing manual efforts by 50%.

Throughout my career, I have worked with leading companies like Intelica Consulting and Tranzact, where I successfully implemented solutions that drastically reduced processing times and costs. For instance, I reduced processing time from four days to just four hours and cut Write IOPS costs in RDS from $1500 to $300 daily by optimizing queries. My hands-on experience with cloud platforms like AWS and Azure, along with my certifications in Databricks, further solidify my capability to deliver scalable solutions tailored to the fintech and retail sectors.
