I build web products end to end and the AI tooling that ships them faster.
Senior Fullstack Engineer with 9+ years delivering web applications end to end, strongest on UI-driven front-end architecture with Angular and the .NET ecosystem. De facto tech lead at CEMEX: led architecture for a 5-person team and built the component library reused across 5 enterprise apps. In parallel I run El Sheimus, an indie studio where I build AI-native products: agent pipelines that turn tickets into pull requests, MCP servers, LLM integrations and a shared Go API powering several live SaaS.
