About Me

Filipe Lehmann

I want to be a bridge between people and technology.

I'm a software engineer with 3+ years of experience, a lifelong learner, and a language enthusiast currently based in Curitiba, Brazil. I'm looking to partner with people and organizations to carry out worthwhile projects, create good relationships and fight entropy.

Specializing in React, Next.js, TypeScript, and modern UI development, I’ve contributed to full product lifecycles - from building B2B SaaS platforms from scratch to internationalizing their interfaces and improving system reliability through Atomic Design, Clean Architecture and automated testing with Selenium and Cypress.

I’m driven by the opportunity to build things that are both technically solid and genuinely useful - solutions that people rely on and enjoy using. I’m at my best when I’m deeply focused on creation with peers that are also engaged in the mission of refining our craft and ourselves.

Invite me to a project!
