I solve complex data problems that others can't. With 20+ years of expertise in database systems and data migration, I specialize in: - Microsoft SQL Server migrations and architecture (on-premise and Azure) - Large-scale data imports/exports (handling files 10GB+) - ETL development using SSIS, PowerShell, Python and custom solutions - Cross-platform database migrations (SQL Server, Oracle, MySQL, SQLite, RedShift) - Data integration between disparate systems My approach is pragmatic and efficient. When you have CSV files that won't import, databases that need migrating to the cloud, or systems that can't talk to each other, I deliver solutions that work—fast. I've successfully: - Migrated 11GB geographic databases to Azure SQL - Built custom RFID and inventory tracking systems - Created data pipelines between legacy systems and modern platforms - Designed scalable database architectures for growing businesses - Implemented automated ETL processes to eliminate manual data entry My clients appreciate that I not only fix their immediate problems but also: 1. Explain what I'm doing in plain language 2. Transfer knowledge so your team can handle routine tasks 3. Remain available for quick questions even after project completion Whether you're dealing with problem CSV files, need a database redesign, or require a complex migration to the cloud, I'll get it done right the first time. Let's schedule a quick call to discuss your data challenges.
