Hire the Best ETL Developers
in the United States

I help businesses turn raw operational data into reporting systems, dashboards, and decision tools that improve visibility, reduce risk, and support better business decisions. My work combines SQL development, data warehouse design, reporting, KPI analysis, and business-focused data interpretation. I am especially effective in environments where data exists but is difficult to use, inconsistent across systems, or not yet structured for reliable reporting. I can help with: • SQL query development and optimization • Data warehouse design and ETL structure • Reporting views and business reporting layers • Dashboard development and KPI reporting • Risk analysis and performance measurement • Data quality investigation and reconciliation I also bring strong project awareness and business context, which helps ensure technical work aligns with operational goals and real decision-making needs. Where needed, I can support custom technical solutions and software-oriented problem solving as part of broader data initiatives.

I’ll help you map the cleanest path from scattered systems to a reliable data platform.

Hi, I create high-performance, full-stack data applications that turn raw, complex data into clear business intelligence and user-friendly interfaces. As a senior engineer with 8+ years of hands-on experience, my core strengths include: - Building reliable, large-scale ETL pipelines in Python, using tools like Airflow, Pandas, and Spark to manage high-volume data efficiently and without failures - Developing clean, interactive front-end experiences with React, TypeScript, Redux, and styling frameworks like Material UI or Tailwind CSS, perfect for data dashboards and visualizations that drive decisions - Creating secure, scalable back-end services with FastAPI, Flask, or Django; relational databases like PostgreSQL; cloud warehouses such as Snowflake or BigQuery; and multi-cloud environments (AWS, GCP, Azure) featuring well-designed REST APIs and microservices - Designing end-to-end architectures for real-time streaming, batch processing, seamless zero-downtime deployments, and robust production infrastructure One of my proudest achievements: I spearheaded the overhaul of an outdated ETL workflow for a growing SaaS company. By shifting to a modern stack of Python, Airflow, and Snowflake, we dropped daily run times from more than 4 hrs to under 45 min. This delivered major savings, around $180,000 annually in cloud expenses, while powering live, responsive React dashboards for instant analytics. Businesses bring projects to me because I focus on delivering high-quality, maintainable solutions that solve actual problems quickly, whether revamping slow legacy data systems, speeding up reporting platforms, or taking new SaaS capabilities from idea to live deployment. If you're ready to tackle a challenging data or full-stack project, Please let's connect and discuss how I can help make yours succeed. Best regards,

Previous work has involved data analytics, SQL reporting, high-volume data pipelines, API development, data visualization, and ETL/ELT. My solutions emphasize reliability, efficiency, and simplicity. The databases and programming languages that I use most often are PostgreSQL, MongoDB, Redshift, Snowflake, BigQuery, MySQL, Python, and Node.js, but I have experience with others. For data visualization, I use Tableau and develop custom solutions.
