What I'm looking for

I'm looking to build reliable cloud data platforms, ETL pipelines, and streaming systems where I can improve data quality, analytics reliability, and infrastructure efficiency.

I've built cloud data infrastructure for Lemon Tree Hotels, Zalon, Techtonic, and Tekniko, spanning hospitality, e-commerce, and SaaS. My work focuses on automated ETL pipelines, streaming systems, and dependable analytics workflows.

At Zalon, I designed real-time ingestion with AWS Kinesis, Lambda, and S3 for 5M+ daily events, and built 10+ Glue, PySpark, and Python pipelines for 500K+ SKUs. I also reduced monthly data infrastructure costs by 28% through Glue right-sizing and automated S3 lifecycle policies.

At Lemon Tree Hotels, I've migrated roughly 65 AWS Glue jobs into a pipeline-oriented Git repository, added 300+ tests, and modernized customer deduplication in PySpark. I also publish technical articles and have earned Grandmaster rank on DataPathSala.
