What I'm looking for

I’m looking for a team where I can build production-ready AI agent workflows—especially scalable RAG, semantic search, and low-latency microservices—while owning backend architecture, async processing, and measurable performance improvements.

I am a Fullstack AI Engineer, having 4+ year of Experience.
I love cooking and AI tools.
