Database tester with seven years validating data and database logic for a software company in Columbus. Tests the layer most testing misses — verifying data integrity, ETL and migrations, stored procedures and the queries that feed the application, so the numbers users see are actually correct. Built a data-validation test suite that caught migration errors before a major release went live. Writes and runs SQL-based test cases, validates ETL and data transformations, tests stored procedures and performance, and manages defects with developers and data engineers. Strong on both deep SQL skill and the testing discipline the role demands, where a data bug is silent and dangerous. Methodical and protective of data accuracy. Looking for a database-tester, QA-engineer or data-quality role on systems where the data has to be right.

Education

Ohio State University

BSc in Information Systems (August 2011 to May 2015)

ISTQB / Microsoft

Highlights

Caught migration errors

Built a data-validation test suite that caught migration errors before a major release went live. Catching bad data before launch prevents silent, costly problems for users.

Guards the data layer

Tests the database and data layer that most testing overlooks but that users ultimately trust. A data bug is invisible until it has already done damage.
Data-Validation Test Suite

Data-Validation Test Suite

Database Tester (January 2019 to August 2019)

Built a reusable data-validation test suite covering source-to-target mappings and reconciliation, which caught migration errors before a major release reached production and became the team's standard approach for data testing.

Stored-Procedure Test Automation

Database Tester (January 2020 to September 2020)

Automated the testing of the database's stored procedures and SQL logic, building a suite that ran on every change so data-layer regressions were caught long before release.
Certifications

SQL & Software Testing
