# Lucas Martins — Software Engineer

> Software Engineer with 4+ years. Most projects I've rescued didn't have bugs, they had bad decisions. Lack of architecture, coupling that blocks the team, stack chosen on hype. I understand the problem before writing a single line, because refactoring is expensive and rewriting is worse.
