About

Lucas Batista

Full-stack developer — web systems, SaaS and digital products

I build digital systems from scratch — from the database model to the final interface. Every project is treated as a product: I start by understanding the problem, not the technology.

I work with React, Next.js, Node.js, TypeScript and Flutter to build web systems, SaaS products, landing pages and apps. The technical side is the means — the business result is what matters.

I'm not interested in shipping code that just checks off requirements. I want to ship software people enjoy using, that solves a real problem and that the business can grow on.
