What I'm looking for

I’m looking for a role where I can build SRE-grade, cloud-native data pipelines and also grow into data science and ML pipelines using Python-based tooling—while driving reliability, incident readiness, and advanced analytics.

I’m a Results-driven Data Engineer with 8 years of experience designing and delivering ETL pipelines, data warehouse solutions, and cloud-native data platforms. I bring proven expertise in Snowflake, PySpark, Informatica (PC/IDMC), Teradata, Hadoop, and AWS.

In my current role, I design/implement scalable and distributed ETL pipelines (Batch, Near real-time) and analyze legacy environments to build CI/CD roadmaps using Jenkins and GitHub Enterprise. I’ve led Informatica PC to IICS migration and automated CDI tasks via CAI, while also owning production readiness standards like SLIs/SLOs, error budgets, runbooks, and rollback procedures.

I operate with SRE practices—incident management, RCA, DR testing, and resilience engineering—and I improve operational efficiency through runbooks, backfill/re-run strategies, and batch impact assessment automation. I’m also expanding into data science, ML pipelines, and advanced analytics, contributing to AIVERSE GenAI (RAG/vectorization) initiatives for semantic search on EDW datasets.
