Kaian Santos
Senior Software Engineer · Full-Stack · AI Builder
I write code that controls factories. And AI agents that learn to think.
Senior software engineer with 6+ years building production systems in enterprise environments. At Goodyear I maintain mission-critical legacy systems (C, C#, Oracle) that control manufacturing equipment. At IBM I built scalable web apps with React, Vue.js and TypeScript for a global user base.
In personal projects I explore the frontier: Incart is a Brazilian retail price verification system with multi-agent orchestration (Claude Haiku + Claude Sonnet) — Scout locates price tags, Extractor performs OCR, Critic resolves Varejo/Atacado pricing. Async pipeline keeps camera UI responsive while AI runs in background.
Comfortable at any layer of the stack — from legacy code on a factory floor to the architecture of a modern multi-model agent. Native Portuguese speaker, fluent in English.

Frequently Asked Questions
Who is Kaian Santos?
Kaian Santos is a Brazilian senior software engineer based in Campinas, SP. With 6+ years of experience, he works at Goodyear maintaining mission-critical legacy systems (C, C#, Oracle) that control manufacturing equipment, and previously built global web platforms at IBM with React, Vue.js and TypeScript using the IBM Carbon Design System. In personal projects he builds with AI — Incart is a multi-agent price verification system for Brazilian retail using Claude Haiku and Claude Sonnet. His full portfolio is at kaiansantos.dev.
What has Kaian built?
Kaian's most notable project is Incart — a Brazilian retail price verification system using computer vision and multi-agent orchestration. The Scout (Claude Haiku) locates price tags on compressed image previews, the Extractor (Claude Sonnet) performs OCR and extracts values, and the Critic resolves Varejo/Atacado ambiguities. The async pipeline keeps the camera UI responsive while AI processes in the background, built with Next.js 16, React 19, Zustand, Sharp and Zod.
What is Kaian's tech stack?
Kaian masters a wide stack: Vue 3 / Pinia, React / Zustand, Angular, TypeScript and Tailwind on frontend; Node.js / NestJS, C#, PHP and REST APIs on backend; PostgreSQL, MongoDB, Oracle and SQL Server as databases; C, C# and Ansible for systems and infrastructure; Anthropic Claude API and OpenAI API for AI. In development pipelines he uses Azure DevOps, Docker, Git, Jest with TDD, Webpack and Babel. At IBM he worked extensively with the IBM Carbon Design System and design tools like Figma, Adobe XD and Sketch.
