Hello, this is Nacho Rapallo

Te puedo contar todo esto en Español

I am a versatile developer (frontend/backend). What you might call a full stack developer.

I feel more identified with the term Software Craftsman

I focus more on the results than on languages, tools, or frameworks.

Design is about removing things.
Choosing what matters, highlighting it, and getting rid of everything else.

Lifelong Learning: I am in a constant search/learning of new and better methodologies.

What about AI?

My current way of working is based on spec-driven development, an approach where you first write a detailed specification of what you're going to build, in structured and well-organized natural language, and only then write the code.

Code becomes a consequence, not the main document. The key idea is to invert the usual hierarchy: the specification document is the source of truth, not the code. And this document evolves throughout development, making the code adapt to it.

The quality of a specification depends on accumulated experience and continuous learning, not on the improvisation of Vibe Coding, which I avoid entirely.

This way of working with AI tools allows an experienced developer to operate like a full team. What used to require several people coordinating can now come out of a single well-planned flow. Same result, less friction, more control.

Developer Stack 2025

I'm sharing my current stack as a presentation letter so you can see how I think in terms of technological decisions.

Apps should use the same technologies adapted to different devices to take advantage of all their native possibilities.

My development stack is changing over time adapting to the needs I have in my projects.

If we take a snapshot of the current moment, my preferences would be these:

Mobile

• Typescript
  Impossible to think of a new project without data typing.
• React Native
  100% native React on mobile.
• Expo
  I believe there's currently no better way to make hybrid applications for iOS/Android/Web. Especially if we want to share code between platforms and not reinvent the wheel.
• Expo DOM Components
  Being able to use web components within a native application is ideal for many components and use cases. It saves us time and reinventing things that already work perfectly.
• Moti / ReactAnimated
  "Write once, animate everywhere".
  Fast and fluid animations and transitions taking advantage of native device capabilities.
• Uniwind/Nativewind
  Tailwind for mobile: I can't find a better way to design styles that adapt equally to any device and screen.

Web

• Typescript
  Type management is vital in any new project that wants to be scalable and maintained over time.

• React
  Version > 19. Always the latest versions of React to take advantage of their improvements.

• API
  Restful or GraphQL, API depending on the project.

• React Server Components
  Communication between server and client in a typed and fast way.

• NextJS / Vite
  Depending on the project size.

• Tailwind
  Responsive components adaptable to any screen size.

Databases

• PostgreSQL / Redis / SQLite
  (depending on project needs)

Libraries

• The hybrid libraries I use in all types of projects

  Zod
  The type management and validation I like the most.

  Tanstack Query / Tanstack Store / Zustand
  State management, both server and client side.

  Tanstack Forms
  Form handling, with validations and typing.

Hosting

• Vercel / EAS hosting / AWS / Google Storage

Cloud

• Google Storage / AWS

Github

• Management and repository of all my projects

n8n

• Task management. Automating projects into small tasks is vital in any project.
  If we use AI, scraping or integrations with different external services, tools like n8n make our life easier.

tldraw

• It's my favorite way to plan projects, draw, share ideas and sketch together with the client the solutions we're going to develop together.

Figma

• Design and prototype of any project or component.
  I don't start programming if I don't previously have clear its functionality and design.
