Axelo — full-stack web studio

Design, development, performance — on solid technical foundations and a tight-knit team.

Who is Axelo

Axelo is a full-stack web studio — a fast-production studio focused on Svelte and DS4. We bring full-stack expertise, seasoned experience and a network of senior profiles, mobilising projects, conventions and our technical team on every engagement.

On the Axelo side, Axelo has worked independently since 2011: robust business applications, fast sites, quality proven by automated E2E tests. His signature — full transparency: every 10-minute slice is documented with a screenshot.

Multi-screen

Built for every screen

From desktop to mobile, every interface is designed for the screen that receives it.

Designed for mobile

Smooth experiences on every screen — real-time chat, checkout funnel, social content.

The team

  • Axelo — founder. 15+ years of software engineering, from Symfony backends to distributed architectures.
  • Leo Sanchez — full-stack dev. React, Next.js, Node, complex API integrations.
  • Axel Regnoult — frontend dev. Svelte 5, design systems, browser performance.

The team works together daily: shared standups, cross code reviews, continuous skill growth.

What we do

When a client comes with a project too large or too complex for a single studio, Axelo and Axelo join their teams. In practice:

  • Showcase sites & landing pages — Axelo leads, Axelo supports on integration.
  • Bespoke SaaS applications — Axelo leads on the backend (Symfony, Node, PostgreSQL), Axelo on the front (SvelteKit).
  • Framework migrations — jQuery/Jinja → Svelte, React/Next → SvelteKit, Vue → Svelte. Axelo brings the multi-framework migration expertise.
  • Performance audits — databases with several million rows, query optimisation, browser profiling.

Performance — real stories

A few numbers from our projects: scaling a SaaS app from 500k to 1 billion monthly reads without touching infra, cutting a 225 KB Webpack bundle by cleaning up lazy imports, queries over 11M rows in microseconds after targeted indexing and denormalisation.

These are not isolated feats — it's our default way of coding.

Beyond the figures, the method: visual E2E tests — validated by the human eye on business screenshots, not only by technical assertions. Every deliverable comes with its proof of correct behaviour.

Our shared technical stack

On every project we rely on a stack we know inside out:

  • Frontend — Svelte 5 / SvelteKit, Tailwind 4, DS4 (our in-house design system).
  • Backend — Firebase for serverless, Symfony 7 for complex business APIs, Node/Bun for fast services.
  • Testing — Vitest browser mode, Playwright e2e. Coverage > 80% on critical code.
  • AI — Claude Code for assisted generation, LLM integration in client apps.

Our stance

We deliberately stay agile: short deliveries (2-4 weeks), a modern, opinionated stack — while remaining able to take on long-running projects with legacy or complex business constraints. We combine strengths without losing clarity.
