Project details

Got a SQL query that’s slow, failing, returning duplicates, or simply not doing what you need?

Send it to me and I’ll diagnose the problem, optimize or rewrite the SQL, and explain what I changed and why.

I bring 20+ years of hands-on database and analytics experience, including nearly two decades working in complex enterprise environments. My background includes Oracle SQL/PL/SQL, SQL Server, data warehousing, ETL, dimensional modeling, Databricks, and data migration.

Depending on your project tier, I can:

 • Diagnose query errors and performance problems
 • Rewrite inefficient or overly complex SQL
 • Optimize joins, filters, subqueries, and aggregations
 • Investigate duplicate or incorrect results
 • Review execution plans when provided
 • Identify potential indexing considerations
 • Improve readability and maintainability
 • Explain what changed and why
 • Provide clean, revised SQL

This service is focused on solving specific SQL problems—not selling you a large consulting engagement when you only need a query fixed.

Send me the troublesome SQL, tell me what’s going wrong, and I’ll take it from there.

Two areas of expertise. One person who actually does the work.

DATA, SQL & ANALYTICS

I help businesses solve database and analytics problems - from a troublesome SQL query to data warehouse architecture and modernization.

I bring 20+ years of hands-on data experience, including 19 years at State Street, where I helped build and evolve an enterprise analytics platform supporting internal teams, institutional clients, regulatory reporting and executive analytics.

I can help with:

• SQL troubleshooting and query optimization
• Oracle SQL / PL/SQL
• SQL Server / T-SQL
• Slow queries, duplicates, joins and stored procedures
• Data modeling and ERDs
• Kimball dimensional modeling
• Star schemas, fact tables and conformed dimensions
• Data warehouse design
• ETL / ELT troubleshooting
• Data migration and reconciliation
• Data cleanup and transformation
• Oracle-to-Databricks modernization
• Databricks / PySpark troubleshooting and validation
• Power BI / BI architecture
• Legacy database modernization

I’m equally comfortable fixing one ugly SQL query or helping untangle a larger data architecture problem.

CREATIVE, VIDEO & AI

I also produce short-form video ads, AI-generated UGC and direct-response creative for DTC, e-commerce and service brands.

Most creators make videos. I build creative systems.

My KAIRA project demonstrates the approach: a fictional indie artist with an entire single-release campaign built from one production system - hero reel, cutdowns, story frames, quote cards, Spotify Canvas, UGC content, captions and hooks, all sharing one visual world.

Recent work also includes craft-beer spec advertising, AI UGC campaigns, product/lifestyle creative and production-ready commercial storyboards.

NEED SOMETHING FIXED?

If you've got a SQL problem, broken data process, reporting issue or a creative brief sitting on your desk, send it over.

Tell me what's wrong and what "done" looks like.
