Hello, I understand you need an Azure Data Engineer to build and maintain data pipelines involving ingestion, transformation, validation, incremental processing, and structured/semi-structured data using Azure Databricks, PySpark, SQL, ADF, ADLS Gen2, and Delta Lake. The goal is to deliver reliable and scalable ETL/ELT workflows. Here’s what I can provide: • Python-based data processing, JSON parsing, cleansing, deduplication, and validation • Strong SQL, backend/API development, database handling, and ETL workflow understanding • AWS cloud, Docker, Git, and scalable application experience transferable to Azure environments I bring over 4+ years of experience in Python, SQL, Django, AWS, Docker, REST APIs, and backend development, with a strong focus on reliable and scalable systems. I’m comfortable learning and implementing new cloud technologies and can work with your existing architecture and requirements. Just to clarify a few things: • Is the project primarily focused on existing Databricks pipelines or building them from scratch? • What is the expected weekly availability and on-site schedule in Pune? Please come to the chat box to discuss more about your project. Best regards Indresh Kushwaha

You need a battle-tested Azure Data Engineer who can build reliable, scalable pipelines handling structured and semi-structured healthcare and insurance data across the full Azure modern data stack, from ingestion through validated Delta Lake output. My approach: I would architect ADF pipelines for both historical loads and incremental ingestion into ADLS Gen2, implement Bronze-Silver-Gold medallion layers in Delta Lake, handle nested JSON parsing and FHIR-adjacent structures in PySpark notebooks, and enforce data quality through source-to-target reconciliation checks before any downstream consumption. Delta MERGE operations for upserts and deduplication would be standard practice, not afterthoughts. My stack proficiency covers everything listed: Databricks, PySpark, ADF, ADLS Gen2, Delta Lake, Databricks SQL, SQL Server, and Git-based version control with basic CI-CD pipeline awareness. Key risks I proactively handle include schema drift in semi-structured sources, partition strategy for query performance, and data sensitivity governance given the healthcare domain. I can commit part-time with consistent availability and can typically be productive from day one without hand-holding. What does your current pipeline architecture look like, and where is the biggest pain point right now?

Hi, Your pipeline needs efficient handling of nested healthcare JSON and incremental updates in Delta Lake without performance degradation during upsert operations. I will build the ADF ingestion layer to land semi-structured data into ADLS Gen2, followed by PySpark transformations in Azure Databricks using Delta MERGE patterns for source-to-target reconciliation. This pipeline can be fully deployed and tested within three business days. Are the incoming healthcare payloads streaming via Event Hubs or landing as batch files in Blob storage?

Hi, I'm Zaryab. I can support your Azure data engineering project end to end — ADF ingestion, Databricks PySpark notebooks, ADLS Gen2 and Delta Lake, incremental processing with MERGE/upsert, nested JSON parsing, deduplication, and source-to-target reconciliation. I'm comfortable building the full flow: SQL Server source → ADF/Databricks → ADLS Gen2 → Delta Lake → transformation and validation → unified target, with performance tuning and documentation. Quick questions before I confirm: is the Pune on-site requirement firm, or can this be remote? And roughly how many hours per week do you need? Happy to share similar project details on request. Best, Zaryab

The useful part of this system won't simply be a working interface. It will be how well it delivers answers grounded in your material instead of generic model guesses. That means retrieval quality, source grounding, and answers that stay useful as the document set changes. I'd keep the implementation focused: ground answers in the source material with clear retrieval and citation paths; tune chunking and ranking so responses stay accurate as the corpus grows; and add evaluation checks for hallucinated or low-confidence answers. I currently work on production AI assistants involving retrieval, conversation workflows, tool integrations, and multi-user state management, so much of the underlying architecture here is familiar. I can work in a fixed-scope first delivery over about 10 days, with clear milestones as details firm up. Could you share the document sources and how answers should be cited or used so I can suggest a practical retrieval setup?
