Hi, I’m Cornel. I design and build web platforms for agencies and businesses.

Since 2012 I’ve been building them through Master WebTools, my studio in Cluj-Napoca: WordPress and WooCommerce sites, Laravel apps, and the APIs and services that connect them. Lately that includes LLM features, AI agents, MCP servers and semantic search. I also maintain Search Analytics, a WordPress plugin used on 3,000+ sites.

The first consultation is free.

What I do

  • System architecture

    Platforms made of several apps, websites and services: microservices, queues, shared APIs and the data flowing between them, designed to scale and stay maintainable.

  • AI & LLM integration

    LLM-powered features inside products, agents that automate workflows across systems, and RAG with embeddings and semantic search so answers come from your own data.

  • MCP servers

    Model Context Protocol servers that let AI assistants like Claude work with your own systems: databases, APIs and internal tools, with access limited to what each assistant should see.

  • Laravel & APIs

    Custom Laravel applications and services: reporting tools, product catalogues, mobile app backends, REST APIs, and integrations with third-party systems.

  • WordPress

    Custom themes and plugins, WooCommerce stores, and admin screens built with Advanced Custom Fields, whether it’s the whole site or one part of a larger platform.

“I hired Cornel to develop an international e-commerce platform serving both B2B and B2C customers. […] He took ownership of the challenges and brought his own ideas to the table, which I valued throughout our collaboration.”
