Product positioning, trust, scope, and pages that explain the offer instead of circling around it.
Guide
Local service site guide
Service positioning, trust signals, contact friction, and local-intent structure for client-facing websites.
Guide
SQL Server update guide
CU vs GDR, build-number lookup, patch planning, and the practical workflow behind the live tracker.
SQL reference
SQL Server updates people actually bookmark.
The live SQL Server updates tracker is the strongest recurring reference page on the site. It is built for build-number lookup, version history checks, and patch planning, not filler content.
Lead reference
SQL Server latest updates
Live patch table plus version-history lookups built from Microsoft's update source. Useful on its own, and a natural entry point into the consulting side later.
Featured pages
Other pages with real depth.
Product pages, client case studies, and profile context with enough depth to stand on their own.
Product work
Passary
Offline password manager direction built around ownership, isolation, and practical security choices.
Client case study
DJ Canis
Service-site work focused on clearer positioning, stronger trust, and better booking flow.
