What I'm looking for

I seek a hands-on data engineering role where I can build scalable pipelines, work with modern big data stacks, collaborate with business teams, and drive measurable performance improvements.

I am a data enthusiast and experienced big data developer specializing in building fault-tolerant, high-performance data ingestion and processing pipelines using Spark, Hadoop, and related technologies. At a large consulting firm, I designed and implemented solutions that improved ingestion efficiency, reduced downstream processing time, and migrated legacy workflows to modern Spark‑based applications.

I take ownership as a sole developer for business teams—collaborating with stakeholders, delivering POCs, and building reusable tools like a Spark SharePoint connector and dynamic flattening logic for semi-structured data. I focus on practical engineering that delivers measurable performance gains and enables analytics-ready data.
