Senior Data Engineer delivering scalable GCP/Azure pipelines, migrations, and reliable monitoring.
IndiaWhat I'm looking for
I’m a Senior Data Engineer with 5 years of experience spanning Agile engineering, cloud architecture, and DevOps automation. I build robust data pipelines and modern data platforms that prioritize integrity, performance, and cost efficiency from design through production operations.
I’ve led end-to-end enterprise migrations with a proven focus on zero-/low-downtime outcomes, including Snowflake to BigQuery transformations. I streamline ETL/ELT workflows using GCP services like Cloud Composer, Dataflow, and Dataproc, while executing complex SQL in BigQuery to improve accessibility and optimize post-migration schemas and queries.
To keep systems dependable, I combine monitoring, alerting, and operational discipline. I’ve set up dashboards and alerts across GCP services using Datadog, reducing P1/P2 escalations by 90%, and I support production workflows through onboarding, issue resolution, troubleshooting, and incident response.
I also bring engineering leadership and delivery momentum to every engagement—mentoring teams, enforcing CI/CD, and managing infrastructure with Terraform and Azure DevOps. Whether it’s Python-based Cloud Functions for automation, QlikView dashboards for actionable insights, or GitHub/Linux-based deployment management, I aim to deliver scalable solutions that teams can confidently run and improve.
