₹400-750 INR / hour

I’m in the start of a performance-focused data-migration effort that moves our current datasets into Snowflake, with Geneva and straight SQL powering the pipelines. To keep momentum, I need someone who can help on the hands-on analyst work while thinking like a Business Data Analyst. What I still have to finish centres on two areas: • Data extraction and transformation – mapping existing schemas, writing efficient SQL, and using Geneva/Snowflake utilities to cleanse and reshape data so downstream analytics run faster. • Data loading and validation – building repeatable load jobs into Snowflake, designing row-level and aggregate checks, and documenting reconciliation so stakeholders can trust the numbers. Acceptance criteria • Clean, reusable ETL scripts committed to our Git repo. • Loaded Snowflake tables that match source counts and sample query results within agreed thresholds. • A short run-book describing load steps, validation logic, and any performance observations. If you’re comfortable juggling Snowflake, Geneva, and solid SQL while keeping performance top of mind, let’s connect.

Hi, Your Snowflake migration requirement aligns well with my 4+ years of experience in data engineering and ETL development. I have strong expertise in SQL, schema mapping, data transformation, and building validation checks (row count, reconciliation) to ensure data accuracy. I’ve worked on cloud-based data pipelines and performance optimization, and I’m comfortable handling end-to-end data migration tasks. I can deliver clean ETL scripts, accurate data loads, and clear run-book documentation. While I haven’t worked with Geneva directly, I can quickly adapt. Available to start immediately. Thanks, Kamendra Mobile :9926422422
