I build software that ships and holds up

From the first screen to the security behind it. I take an idea from zero to production and keep it simple enough to maintain.

Method & Philosophy

I start from the end.

Most projects stack up tools before knowing where they need to lead. I do the opposite: I start from the outcome the client needs, then build the shortest path to it. Often that means fewer accounts, fewer screens, fewer subscriptions to pay every month.

Inside Alten I build this kind of system: security alerts escalated by automatic phone call, tickets created the moment a vulnerable machine is detected, a front end to drive AI agents for risk analysis.

Selected Case Studies · 2024–2026

The four projects, up close.

From bespoke client marketing websites to automated SaaS workflows and systems. Here is how each project was conceived, structured, and shipped.

Immersalis website interface preview immersalis.tracevault.tech Live marketing website

Immersalis

The site sells the approach as much as the service.

Context
A firm that unblocks stalled internal software projects, with no site to carry its message.
What I did
Full marketing site: positioning, message structure, visual identity, launch.
Outcome
An online presence at the firm's level of rigour, ready to show in a meeting.

OnePost application interface preview

OnePost

Three posts from a single action.

Context
Publishing one video to three platforms is the same manual work three times over.
What I did
A web app that posts to YouTube, Instagram and TikTok in one click. Designed, built and deployed solo.
Outcome
From three separate uploads to a single action with zero repetitive friction.

Haras des Moutonnières website preview moutonnieres.tracevault.tech Equestrian centre booking & showcase

Haras des Moutonnières

A sales tool built to win the client.

Context
An equestrian centre with a rich offer that was unreadable online.
What I did
Full rebuild: clear pricing table, booking, activities. Built to convince in a meeting.
Outcome
A concrete demo, used as a primary sales argument with the prospect.

Serah Aouate, photographer

The site steps back and lets the images speak.

Context
A photographer with a wide eye (travel, family, architecture, documentary) and no online gallery to show it.
What I did
Portfolio site: galleries by series, quiet navigation, full-frame images, contact page.
Outcome
A showcase that puts the photography first, with a clear and elegant point of contact.

Who I am.

I've been coding since high school to solve real problems. That's what took me from web development to systems security, without dropping one for the other.

Based near Paris. Away from code: sport and music.

Apprentice at Alten since 2023, starting a master's in cybersecurity in 2026. The rigour of a consultancy applied to every site and system delivered: tested, documented code that anyone can pick up.

Common questions

How much does a project cost?

Usually between €3 ,000 and €7,000, depending on what needs building. The exact figure is set after a first call, no commitment.

How long does it take?

A few weeks for a full marketing site. An automation system depends on what it replaces: we scope it together before starting.

How does follow-up work?

The project ships tested, documented and ready to hand over. You stay independent after delivery, with no forced dependency.
