Hi, I'm
Fran Arnau.
Full-stack engineer at undf.agency. I ship products end-to-end — Laravel and Vue, from schema to UI — on my own.

Strengths
What I bring to a team.
Six things you can hire me to do well — measured against shipped work, not slides.
End-to-end ownership
From schema design to the deployed UI. I scope it, build it, ship it, and keep it alive.
Deep Laravel + Vue
Years of daily Laravel and Vue across multi-tenant SaaS, ERP modules and embeddable widgets. The stack I reach for first.
Real full-stack range
Backend systems, editorial frontends, motion and 3D. I treat infra, copy and animation as one craft.
Independent operator
Most of my projects ship without a team. I move from blank page to production without supervision.
Architecture-led, not order-taking
I pick the tradeoffs — DB-per-tenant, dual-layer payments, idempotent bootstrap — and defend them.
AI as force multiplier
AI is woven into how I work, not bolted on. Guardrails over hype: deterministic JSON, anti-slop prompts, audit-first runs.
Looking for someone who can own a feature from idea to production without you holding their hand? Let's talk.

Solo · live on undf.agency
A Vue module dropped into a heritage site.
Interactive pricing builder for a 50-year decorative-plaster atelier — embedded inside a site I did not design, so my piece had to fit a refined gallery-style host.
