I build reliable cloud data pipelines and streaming systems that improve analytics, quality, and infrastructure efficiency.
What I'm looking for
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.
