hello world, my name is Marcos

Full Stack Developer with a year of professional experience building reliable, user-friendly web applications.Started as an intern at an AI startup and was promoted to Lead Developer within six months, where I led and mentored a team of developers and helped ship the company's MVP.

I build full-stack applications using Next.js, React, TypeScript, and Tailwind CSS on the frontend, with Nest.js, Node.js, and MongoDB on the backend. I've shipped 30+ features across areas like workspace management, real-time WebSocket functionality, authentication flows with Passport.js and JWT, and AWS S3 integrations. Most recently, I've been expanding into DevOps — containerizing applications with Docker, automating deployments via GitHub Actions CI/CD pipelines, and hosting on AWS EC2.

On the frontend I work with TanStack Query for data fetching, Zustand for global state management, shadcn/ui for component design, and React Hook Form with Zod for validation. I write clean, maintainable code following Atomic Design principles to build reusable component systems and separation of concerns to keep codebases scalable and easy to navigate.
