Tools
What I build with
Everything I use to build: the stack, the machine, and everyday apps. Not a list of trends, these are the tools I use to deliver real products.
Stack
What I develop with
The stack I use daily and the reasoning behind each choice: solid backend, functional frontend, applied AI, and security by design.
Backend
The backbone of every product.Django + DRF give me speed without sacrificing structure: mature ORM, built-in admin, and an ecosystem that covers auth, permissions, and migrations. PostgreSQL for serious relational modeling; JWT for decoupled auth between API and frontend.
Frontend
Interfaces that complete the product.Next.js for complete web applications, React + TypeScript for stateful interfaces, and Astro when performance and static content take priority. Tailwind helps maintain visual consistency.
Design & UX
Products that look good and anyone can use.I design in Figma before writing code. Accessibility and technical SEO are not extras: they are part of making the product work for people and for search engines. Performance is a feature.
Product Engineering
Architecture that scales from the first commit.I decide architecture thinking about year two, not just the MVP. Multitenancy, offline-first, and clean APIs are decisions that cost dearly if left for later.
Security
Offensive mindset to write defensive code.I do pentesting to understand how a system breaks and write code that does not break that way. OWASP Top 10 as a minimum checklist; security by design, not patched at the end.
AI Integrations
AI as a real co-pilot, not a shortcut.I integrate OpenAI, OpenClaw, and Claude API where they add real value, such as analysis and context-aware assistance. n8n handles workflow automation. AI accelerates; it does not replace engineering judgment.
Hardware
Where I build it
Modest setup on purpose. If an app runs smoothly here, it runs anywhere: it forces me to really optimize, not cover up with hardware.
Machine

My everyday tools
The apps where I live while building: editing, AI, terminal, and the productivity flow that keeps me focused.

NullBreach
My flagship project: AI-powered security analysis. A Next.js app using OpenAI and Prisma, with its source open on GitHub.
Resources to learn from
I take courses on Platzi, YouTube, and other sources, and turn what I learn into public repos so other people can learn too.
