Project Overview

• We are seeking an experienced Senior Data Engineer with strong Azure cloud, data engineering, and AI/ML platform development expertise to independently design, develop, and deliver a scalable enterprise-grade data platform.
• The project involves building and improving data processing solutions, developing reliable data pipelines, integrating cloud-based services, and preparing data infrastructure to support AI, machine learning, and advanced analytics applications.
• This is an independent contract engagement. The selected developer will take end-to-end responsibility for technical execution, from architecture and implementation through testing, documentation, and final delivery.
• We are looking for someone who can work autonomously, make sound technical decisions, troubleshoot complex problems, and deliver production-ready solutions.
