About Leandro

About me...

Full-Stack Developer who moves fluidly across the entire stackโ€”from MongoDB and Node.js backends to React/TypeScript frontends and templating systems.

At Pl4nner, I navigated complex codebases spanning databases, APIs, and presentation layers including Pug.js templates. At Sinapsis, I migrated 7 large-scale production sites to Sanity CMSโ€”projects like Mรกquinas e Soluรงรตes, handling full content architecture integration.

Technical foundation: React, Next.js, Node.js, MongoDB, and TypeScript, built through 800+ hours at SoyHenry. Currently expanding into cybersecurity fundamentals at TryHackMe.

What I bring: Speed and creativity in execution. My audiovisual production background shapes how I think about user experienceโ€”not just functional interfaces, but beautiful, intuitive ones. I persevere through complex integrations when others pivot.

Remote work. Complex projects. Clients who value someone who sees things through.
