Side Projects

Projects I built and run myself. No team, no funding — just something that needed to exist and the time to make it.

sqltesting.com

Test your SQL. Actually.

SQL developers have plenty of reference sites but almost nothing purpose-built for writing and running test cases against database logic. sqltesting.com is the tool I wanted to exist — practical patterns for testing SQL Server and PostgreSQL logic, with real examples you can apply to production code. Built, hosted, and maintained by me. Runs on a hardened Linux VPS with Nginx and deploys via Git hook.

37solutions.com

Independent consulting for the stuff that actually runs your site.

37Solutions is my independent consultancy for web hosting, database administration, and infrastructure work. Client work has included database rescues, server migrations, DNS overhauls, and performance troubleshooting for small businesses and technical teams. The LLC has been active since 2010. It is also the entity behind the niche publishing work I have done over the years.
