Ashutosh Das

Senior Data Engineer and GenAI Engineer with 5+ years building production-grade data platforms and shipping Agentic AI systems end-to-end across BFSI, Life Sciences, and Aviation. On the data engineering side, I architect petabyte-scale Lakehouse platforms on Azure Synapse, Databricks, and ADLS Gen2 — implementing Medallion architectures, Data Vault 2.0, SCD Type 2 via Delta Lake MERGE, and metadata-driven ADF orchestration. Past projects include a full SSIS-to-ADF/Synapse migration that cut pipeline runtime by 62%, a 5-layer cloud DWH using the ABC framework, and a BFSI Silver layer with 100% audit lineage for incentive compensation data. On the GenAI side, I architected and deployed a production Agentic RAG system on Databricks Mosaic AI — 6 specialised LangGraph agents (Router, SQL, Vector Search, Critic, Validation, Synthesis) over 80+ Delta tables and 8K–12K clinical documents — improving query resolution by 70% for a HIPAA-regulated client. I own the full LLMOps lifecycle: embedding pipelines, hybrid retrieval (HyDE, Cross-Encoder re-ranking, RRF), RAGAS evaluation, MLflow tracing, prompt versioning, semantic caching, and guardrails. I hold 21 active multi-cloud certifications (Azure Expert, Databricks Professional, GCP, AWS) and qualified GATE CS 2024 in the top 6%. Looking for a senior remote role with a US or EU company where I can own data infrastructure or GenAI systems end-to-end.
