I'm Renan.
Frontend Developer with enough backend context.
I work with React, Next.js and TypeScript as daily tools. Node.js, NestJS, API design, database decisions — I contribute past the UI layer when the work demands it.
I've worked on greenfield projects and on restructuring systems already in production. Both are different problems. Greenfield is about making good early decisions. Legacy is about understanding why past decisions made sense before changing them.
I don't have framework ideology. I have decision criteria. Development is about architecture and trade-offs. Not faith in a stack.
My differentiator is thinking critically before deciding. I map the decision, document the trade-offs, consider what breaks, and make sure the choice is defensible later. That habit is slow in the short term and cheap in the long term.
