Message

At Business Service Galop, I develop and maintain the Galop conference platform, which handles registration, participant areas, online payments, invoices, certificates, and reporting. I also work on an on-demand video platform and a training academy registration system.

I independently delivered a bilingual Laravel company website, from specification through deployment, with a CMS, more than 80 tests, and a GitHub Actions CI/CD pipeline. Alongside my commercial work, I build products including TradeMind AI, which combines market indicators with language-model analysis, and ZaitisMind MCP, a shared knowledge base for AI clients.
