Data Engineering

$15/hr Starting at $200

Transform your raw information into actionable intelligence with proven Data Engineering expertise. I specialize in designing, building, and optimizing robust, end-to-end data solutions that drive business value. Whether you're drowning in data, migrating to the cloud, or need reliable infrastructure for analytics and AI, I deliver tailored systems built for performance and scale.

My core competencies cover the full spectrum of Data Engineering:

  • Data Pipeline Development (ETL/ELT): Architecting and implementing efficient, automated data pipelines using Python, SQL, Apache Spark, and orchestration tools like Airflow to reliably move and transform data.

  • Cloud Data Warehousing & Data Lakes: Designing, deploying, and managing modern data warehouses (Snowflake, BigQuery, Redshift, Azure Synapse) and data lakes (AWS S3, Azure ADLS, GCP GCS) for optimized storage and analytics.

  • Big Data Processing: Leveraging distributed computing frameworks (Spark, Hadoop ecosystem) to process massive datasets efficiently.

  • Data Modeling & Architecture: Creating scalable and logical data models (Star Schema, Snowflake Schema, Data Vault) that support your analytics and reporting needs.

  • Data Integration: Seamlessly combining data from diverse sources (APIs, Databases, Files, Streaming) into a unified view.

  • Data Quality & Governance: Implementing strategies and tools to ensure data accuracy, consistency, and reliability.

  • Performance Tuning & Optimization: Enhancing query performance and optimizing data infrastructure costs on cloud platforms (AWS, Azure, GCP).

    Bringing the Just30Fit Shopify store to life has been a journey fueled by purpose, passion, and partnership. I couldn’t have done it without the incredible team at Pioneers Tech. From day one, they didn’t just offer technical support, they leaned in as true collaborators. They understood my vision to empower wellness journeys through curated, inclusive products, and they helped transform that dream into a digital reality. Together, we built more than a store. We built a platform for impact. Thank you, Pioneers Tech, for believing in the mission and showing what it means to be a true partner in innovation. Just30Fit is live, and this is only the beginning!! #Just30Fit #ShopifyLaunch #TechWithPurpose #PioneersTech #WellnessJourney #Gratitude #EcommerceEmpowerment

    Working with Zameer and his team was great - did what they said they would in a timely manner, and didn't give any pushback to changes, etc. - I can't wait for a new project to send them!
