Pan, zoom and select projects. The controls also work without complex touch gestures.
An unapologetically direct layout, bold blocks, and an interactive look at my process.
Understand the context, the people, and the goal before writing code.

WEB · ANDROID · SYSTEMS
I design interfaces and develop applications, APIs, and systems.
From first prototype to production.
01 / ONE SYSTEM, MANY FORMS
Grids, proportion, and space. The foundations of an interface that makes sense.
Forms respond to scrolling. Motion supports the story you want to tell.
Considered interactions connect design, code, and the person on the other side.
03 / INSIDE THE SOFTWARE
Choose a real project and explore how its parts connect. Select each module and replay the information flow.
Web dashboard and Android app provide interfaces for hotel rooms, rounds and staff.
04 / LAYERED EXPERIENCES
Three real projects, three overlapping screenshots. Move your pointer to explore depth, and choose the project in the foreground.

Explore a tunnel of geometric portals: shapes open and the cameramoves forward as color guides the journey. A 3D scene built with code.
02 / SELECTED PROJECTS
A selection of software and tools I have built, from hotel systems to 3D experiences, maps, applications and automation.
PROJECT / 01Hotel operations, GPS patrols and personnel management in a connected web and Android ecosystem.
PROJECT / 02A customized clothing storefront with catalog, orders and an interactive 3D Atelier.
PROJECT / 03Interactive maps, measurements and annotations to plan PUBG matches.
Quoting, embroidery, clients, production, expenses and inventory for a textile workshop.
Reproducible repository setup for Git, Codex and AI-assisted workflows.
Mobile client, API, administration panel and VPS nodes for a VPN platform.
03 / WHAT I DO
I work independently, designing the experience, building the software, and preparing the environment for production.
Product & frontend
Websites, dashboards, PWAs, and commerce flows for real users.
React · Next.js · Vue · TypeScript · CSSBackend & architecture
APIs, business logic, authentication, and data integration.
Python · Node.js · NestJS · SQL · RedisMobile & systems
Android apps, desktop tools, and device integration.
Kotlin · Flutter · Java · LinuxInfrastructure & automation
Deployments, VPS maintenance, CI/CD, and automation.
Docker · GitHub Actions · Shell · Python04 / SOFTWARE ANATOMY
An illustrated SVG instrument: a test bench whose three modules represent interface, logic, and delivery. Its parts explain the process.
Conceptual drawing; not a live system monitor.
01 / 03
Components, interface states, and accessibility.
Choose a module to explore what gets checked.
ABOUT / BUILD WITH PURPOSE
I'm Skull, an independent developer based in Chaco, Argentina. I connect design, applications, data and systems to solve practical problems.
CAPABILITY MAP
React, Next.js, TypeScript and web experience design.
Android, desktop and cross-platform solutions.
APIs, data, backend services and connected systems.
Linux, automation and reproducible deployments.
REAL PROJECTS · DOCUMENTED SCOPE
04 / TOUCH, CHANGE, EXPLORE
This is a small interactive laboratory. Three original experiments to experience design in action.
Change density and distribution. One rule, hundreds of compositions.
Adjust a wave's amplitude. The pulse reacts in real time to every change.
Change an interface state and see how it communicates. An interactive demo that doesn't send data.
Ready to begin.
ONE STATE. CLEAR FEEDBACK.05 / FROM CONCEPT TO SCREEN
Independent software design and development from Argentina. I work across interfaces, APIs, data, and automation.
Understand the problem, the people, and the goal.
Explore composition and test interactions.
Connect interfaces, logic, and data.
Review accessibility, performance, and details.
