About this Gig

Are you looking to design, build, or optimize a scalable, enterprise-grade data platform?

As a Senior Data Engineer with 10 years of experience, I help businesses plan and execute robust data solutions. Whether you need expert architectural guidance or hands-on implementation to build, migrate, and tune your pipelines, I deliver end-to-end engineering tailored to your business needs.

What I offer:

  • Hands-on Pipeline Engineering: End-to-end development, code refactoring, and production deployment using Azure Databricks, Microsoft Fabric, Apache Spark (PySpark), and SQL.
  • Modern Lakehouse Architecture: Complete Medallion architecture setup (Bronze/Silver/Gold layers) designed for high concurrency, low latency, and maintainability.
  • Cost & Performance Optimization: Deep-dive query tuning, cluster configuration, and PySpark refactoring to cut cloud bills and accelerate runtimes.
  • Legacy-to-Cloud Migration: Risk-managed transition execution from legacy databases (Oracle, IBM Db2, PL/SQL) to modern cloud data lakes.
  • Strategic Advisory & Audits: 1-on-1 architecture reviews, system health checks, and actionable platform recommendation reports.
