#01 ABOUT ME

About me

I'm a backend and data developer who turns messy business processes into reliable systems — Also have lots of experience with SEO and GEO.

Data & databases. Administration, optimization and reporting — I'm comfortable owning the data layer end to end. (SQL Server, BI)

Backend & cloud. APIs, integrations and services in Node.js, C# and .NET. CI/CD & Azure implementations — plus some DevOps and project management. (Node.js · Azure · Atlassian)

SEO & GEO growth. I build sites and tools that rank on search and get recommended by AI assistants — with measurable results, e.g. 200k+ impressions from SEO alone.

I also work directly with owners and clients, turning real needs into working tools rather than just code.
