Curriculum vitae

I'm Víctor de la Cruz, an interface-focused full-stack developer with a couple of decades of experience building web applications and the systems behind them.

My work includes:

Building applications from scratch
Translating designs and detailed interface specifications into responsive, accessible interfaces
Implementing design systems and reusable UI foundations
Translating domain knowledge into modules, functions, database schemas, and clear system boundaries
Preparing and transforming data for visualizations, including geospatial workflows with GDAL, GeoJSON, and MapLibre GL
Modernizing existing frontend and backend systems

Current practice

After years of working with Vue and TypeScript, I now spend most of my time with Elixir, Phoenix, LiveView, Tailwind CSS, and PostgreSQL. That combination provides a cohesive foundation for building web applications end to end, from interface details to data models and runtime behavior.

I use agentic engineering workflows with open-source harnesses such as Pi and OpenCode across multiple model providers. I start by exploring the problem, turn what I learn into a plan and concrete specifications, then implement, test, and review the result. When errors appear, I investigate their causes and account for related failure modes instead of prompting at random.
