Cesar Cassiano Schimanco

I’m a Senior AI & Full-Stack Engineer with 15+ years building software for US companies, from .NET and React platforms to, today, AI-first products built around LLM agents. Currently I’m developing a multi-tenant B2B investment intelligence platform centered on an agentic copilot: multi-agent workflows with LangGraph, LLM tool calling, RAG over indexed documents in Elasticsearch, MCP integrations, and a skill-based orchestrator that connects to data sources, monitors changes and executes system actions. I also own the AI quality side, prompt regression evals in CI, model benchmarking across providers, and treating skills and prompts as versioned, tested code. I work AI-first in my engineering process too: project-level harnesses for coding agents, reusable instructions, automated validation against acceptance criteria, and PR workflows with scoped before/after screenshots to make review fast. Before that I spent a decade as a tech lead and full-stack engineer on web and mobile products. healthcare, fintech, banking, e-commerce — with React, Next.js, Node.js, .NET, React Native and Azure/AWS pipelines. I’m also the founder of Brainlite, an AI-first software studio, which keeps me close to the product and business side of what I build.
