About this Gig
Turn your reporting questions into SQL queries you can run again. I write read-only SELECT queries for one SQLite or PostgreSQL database.
BASIC: up to 3 queries across 3 tables, 3 days, 1 revision.
STANDARD: up to 5 queries across 4 tables, 5 days, 1 revision.
PREMIUM: up to 8 queries across 5 tables, 7 days, 2 revisions.
Each package includes commented SQL files, sample CSV results and run instructions. Up to 100,000 sample rows in total, one database engine. We agree on filters, joins, grouping, metrics and expected columns before work starts.
Acceptance: queries run on the agreed sample and match the agreed columns and totals. Revisions cover original requirements; new metrics or tables require a separate quote.
Production administration, migrations, dashboards, scheduling and performance guarantees are excluded. Send your schema, anonymized samples, database version and expected output before ordering.
Gallery graphics and stock photographs are service illustrations. Any demo uses synthetic data, is AI-assisted, and is not a client case.

FAQ
What does one revision include?
One revision corrects the queries to match the agreed filters, columns and totals. Additional tables, new metrics or another database engine are a scope change and require a separate quote.
Do you need access to my live database?
No. Please send the schema and anonymized sample rows instead. You run the delivered read-only queries in your own environment; do not share production credentials.
