I’m Oumar Konaté, a computer engineer and Software Craftsman with more than 17 years of experience building complex, business-critical web applications. I work as a Senior Full-Stack Web Developer across the PHP/Symfony, React and Node.js ecosystems, and I now focus a large part of my energy on AI tooling — designing MCP (Model Context Protocol) servers and automating real engineering work with AI assistants such as Claude Code. My north star is the same it has always been: shipping quality software through clean architecture, testing and continuous improvement.

What I do today

Since January 2022 I work as a senior developer and consultant at Le Figaro in Paris, building and maintaining the back office of its web platforms with PHP 8, Symfony 5, React/Redux, Elasticsearch and MariaDB — applying Domain-Driven Design, CQRS and Hexagonal Architecture in an agile (Scrum) team.

Outside of client work I build and maintain open-source MCP servers that connect AI assistants to real systems (code search, WordPress management, plugin migration audits), and I write about agentic content pipelines, token optimization and software craftsmanship on this blog.
