Experience & Stack

I currently work as a mid-level developer at Grupo Koch SA, where I have been specializing in Artificial Intelligence applied to corporate platform development with multi-agent integration. I use tools such as Claude Code, opencode, and OpenAI to orchestrate intelligent agents that automate processes and centralize internal interactions.

Over more than 2 years of experience, I have built a solid foundation in the frontend ecosystem with TanStack, shadcn/ui, Zod, and Tailwind CSS, as well as good testing practices with Jest and Cypress. On the backend, I work with Node.js and Next.js (Server Actions), OracleDB and PostgreSQL / pgvector databases, asynchronous queues with Redis and BullMQ, and integrations with ERPs and legacy systems. I also build RAG pipelines and document ingestion with LLMs using LangChain, OpenAI, and HuggingFace.
