What I'm looking for

I am seeking a senior data-engineering role where I can build and optimize enterprise ETL/data pipelines, mentor teams, work with AWS/Big Data technologies, and deliver reliable production support within collaborative, SLA-driven environments.

I am a Senior Data Engineer with over 6 years of hands-on experience designing, developing and supporting data warehouse and ETL solutions across domains.

I specialize in Informatica PowerCenter, IICS and Oracle, and have led mapping design, performance tuning, pushdown optimization and migration efforts while working with Big Data tools and AWS services.

I have delivered production-grade data pipelines, implemented SCD Type 1/2, created detailed mapping specifications and workflows, and provided L1–L3 support to meet SLAs for enterprise clients.

I bring strong SQL skills, data modelling knowledge (snowflake/star schemas), experience with Databricks/Glue/EMR/S3, and a collaborative, mentorship-focused approach to ensure reliable, high-performance data solutions.
