Sobre mim
Need an AI system or SaaS product built for real users? I build production-grade RAG pipelines, multi-agent workflows, full-stack MVPs, and intelligent dashboards that scale.
Recent work includes a sub-200ms RAG system, a multi-agent Web3 platform supporting 5,000+ concurrent users, CRM APIs processing 15,000+ requests daily at 99.5% uptime, and React apps improved from 43 to 100 Lighthouse scores.
Stack: TypeScript, Next.js, Python, FastAPI, PostgreSQL/pgvector, Redis, Docker.
Message before ordering so we can define the right scope and build exactly what you need.
