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.
What I develop with
The stack I use daily and the reasoning behind each choice: solid backend, functional frontend, applied AI, security by design, and tools to create content.
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. 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.
- Python
- Django
- Django REST Framework
- PostgreSQL
- JWT
- Software architecture
- PWAs
- Offline-first
- REST APIs
- Multitenancy
- Relational modeling
Frontend & UX
Interfaces that look good and anyone can use.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. 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.

- TypeScript
- Astro
- Tailwind CSS
- JavaScript
- UX/UI
- Figma
- Accessibility (a11y)
- Technical SEO
- Web Performance
Security
Security by design in every line of code.I review every system against OWASP criteria to find its flaws before someone else does and write code that does not break that way. OWASP Top 10 as a minimum checklist; security by design, not patched at the end.
- OWASP
- MITRE ATT&CK
- PTES
- Linux
- AppSec
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.

- OpenClaw
- Claude API
- LLM Workflows
- Prompt Engineering
- n8n
Marketing & Content
Content and digital presence that bring in customers.Marketing and social media training at Platzi and hands-on practice as a content creator on Instagram and TikTok. Canva and CapCut for pieces and video, ElevenLabs and Higgsfield for AI audio and video: the same content I use to show in public how I build.

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.

My everyday machine- Intel Core i5
- 16 GB RAM
- 1 TB
- Linux · Fedora
Windows machine
My other machine- AMD Ryzen 5 3400G
- Radeon RX Vega 11
- 16 GB RAM
- 224 GB
- Windows 11 Pro (25H2)
- WSL2 · Ubuntu
Phone and recording

- DJI gimbal with extendable selfie stick
Peripherals
What I use every day- LG 27" ultrawide monitor (built-in audio)
- Genius keyboard
- Wired ergonomic mouse
- HP 1080p camera (built-in mic)
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.
- fundamentos-javascript JavaScript
- fundamentos-llms Jupyter Notebook
- fundamentos-terminal-linux
- learning-template
- logika-technical-test React-based administrative dashboard developed as a technical assessment for Lógika. Features token-based authentication, protected routes, REST API integration, CRUD operations, pagination, filtering, sorting, dynamic form validation, and file uploads. Built with React, Vite, and Tailwind CSS. JavaScript
- forgotten-portal-writeup Full penetration testing writeup of the Forgotten Portal DockerLabs machine, documenting vulnerability assessment, security findings, and remediation priorities. Includes 28 annotated screenshots, technical and executive reports, PTES methodology, CWE classifications, and MITRE ATT&CK mapping.
Less work by hand, more customers who find you.
I build landing pages, websites, automations, chatbots and custom apps, plus the content that gets you found. Security by design and a fixed price.
MVP in 6 to 10 weeks. Limited availability, I reply within 24 hours.
I build in public
On Instagram and TikTok I show how I build secure software and AI automations, and what I keep learning along the way.
