About Lucas

You're not looking for a developer. You're looking for someone who understands your problem.
Most freelancers talk about their technologies. I prefer to talk about your project.
Fullstack developer for over 5 years, I manage your projects from A to Z — from conception to production. No need to coordinate three providers: one person, one clear vision, one delivered project.
Web: React, Next.js, databases, APIs, deployment.
Mobile: React Native, App Store & Play Store publication.
What makes the difference is that I deliver. On time, with clean code, and without drowning you in jargon.
Have a project in mind? Write to me. You'll get a concrete first response within 24 hours.
