Front-end architecture & consulting · Switzerland

I build the front‑end that still holds up two years from now.

You talk to the engineer who writes the code, not a project manager who delegates. Angular and React architecture, embedded or fixed-scope, on site in Geneva and Lausanne or remote.

What I do

Four ways to work together. One standard.

  • New

    Turnkey project

    From idea to production

    No technical team yet, or a project going in circles? I take it all on: scoping, design, build, deployment, maintenance. One contact from brief to production, who knows every line of the code.

    Duration by scope · Ongoing support

  • Audit & advisory

    Architecture audit & action plan

    Your front-end is slowing your releases, or your team is unsure about a rebuild. I audit what exists, identify what is breaking, and hand you a prioritized, costed plan. Actionable decisions, no jargon.

    2 to 4 weeks · Written deliverable

  • Fixed-scope project

    Fixed-price delivery, scope under control

    For a defined need: design system, NX monorepo migration, React or Angular rebuild, business app. Scope fixed, price fixed, date fixed. The time it takes me is my problem, not yours.

    Variable duration · Defined deliverable

  • Fully booked

    Embedded engineer

    Senior reinforcement in your team

    I join your team as lead or senior engineer: I own the architecture, hold the line on code quality, and level up your developers. No botched handover at the end.

    Long engagement · Remote

Leo Virgo

Senior expertise. Independence by design.

You need a senior front-end engineer, but not a permanent hire. Leo Virgo is exactly that: a principal engineer available on a mandate, with the level of rigor the role demands.

I work where architecture decides everything: high-load business apps, risky migrations, codebases your team needs to still be shipping against in eighteen months.

Several of my mandates run under NDA in regulated sectors. If your project cannot be named as a reference, you are in good company.
