What I'm looking for

I’m looking to build and modernize production Azure data platforms with Databricks and Delta Lake—focused on governance, reliability, and measurable performance. I want to collaborate closely and apply Generative AI (prompting + Vertex AI) to ship practical, production-ready capabilities.

I'm a Senior Data Engineer with 7+ years of experience building scalable, production-grade data platforms on Azure, currently working at Publicis Sapient delivering multi-client consulting engagements across BFSI and retail verticals.

My core stack is Azure (ADLS Gen2, Data Factory, Databricks), PySpark, SQL, Apache Airflow, and Delta Lake, with strong specialisation in Medallion architecture, data governance, and pipeline optimisation. I hold a Databricks Certified Data Engineer Associate credential and Microsoft Azure certifications.

At Publicis Sapient, I'm leading a full-scale legacy-to-cloud platform modernisation for a tier-1 Canadian bank — decommissioning a 50+ workflow legacy system and delivering a new Azure-based data platform on Databricks and Medallion architecture. Alongside this, I led an AI content-generation initiative for a major US retailer using Vertex AI and prompt engineering, saving 3–4 hours of manual design effort per asset.

Previously at Manna Marine Products, I owned the end-to-end Medallion lakehouse on Azure ingestion via ADF, PySpark transformations in Databricks, Delta Lake Silver layer, and Gold-layer datasets for analytics, achieving 99.9% pipeline reliability and cutting deployment time by 40%.

I communicate clearly with both technical and business stakeholders, work well across time zones, and am comfortable owning delivery end-to-end in fast-moving environments.

Location: Bengaluru, India
Timezone: IST (UTC+5:30) — available for overlap with US East (EST/EDT) and US West (PST/PDT)
Availability: Immediate
Expected salary: $62,000/year
