Before we start

I build native iOS apps, web platforms, and full SaaS products — end-to-end.

That means everything from the first UX sketches and UI design through Swift/SwiftUI development, React/Next.js frontends, App Store submission, and post-launch iteration.

I also handle product strategy, branding, and technical due diligence for investors.

If you need someone who can own the entire product lifecycle, not just write code, that's what I do.

It starts with a free 20-minute discovery call — no pitch deck needed, just tell me what you're trying to build.

From there I put together a roadmap with clear milestones and fixed-scope sprints (usually 2 weeks). You get a working demo at the end of every sprint, not a slide deck.

Communication is async by default (Slack, Notion, Linear — whatever you use), with a weekly sync call to stay aligned.

I'm not the kind of freelancer who disappears for 3 weeks. You'll always know where things stand.

For a focused MVP — core features, clean design, one platform — I typically deliver in 6 to 8 weeks.

A more polished minimum lovable product (MLP) with tighter UX, onboarding flows, and backend integrations usually lands around 10 to 12 weeks, sometimes less.

Bigger builds with multiple platforms, complex backends, or regulatory requirements can stretch beyond that, but I scope everything upfront so there are no surprises.

I'd rather ship something sharp in 8 weeks than something bloated in 6 months.

Most of my projects fall between €20K and €150K, depending on scope and duration.

A focused MVP with design and development might be on the lower end; a full product build with backend, multiple platforms, and ongoing iteration sits higher.

I work on fixed-price milestones so there are no surprises. I'm transparent about costs upfront — if your budget doesn't match the scope, I'll tell you and help you prioritize what to build first.

For French companies: I'm certified CII and CIR, which means you can claim at least 20% of my fees back as a tax credit.

I deliberately limit the number of projects I take on — usually two at a time — so I can give each one real attention.

Availability shifts month to month. The fastest way to find out is to book a free consultation call or drop me a message on the contact page.

If I'm fully booked, I'll be upfront about timelines or refer you to someone I trust.

During the engagement

On mobile: Swift and SwiftUI — I've been building on Apple platforms since 2008, long before Swift even existed.

On the web: React, Next.js, TypeScript, and GraphQL. I also work with Node.js, PostgreSQL, and deploy on platforms like Clever Cloud and Vercel.

I pick tools based on the problem, not hype. If a project needs UIKit for fine-grained control or a specific backend stack, I'm comfortable going there too.

Absolutely — and I do it more often than you'd think.

I've rescued projects that were stuck in development hell, inherited legacy Objective-C codebases that needed modernizing, and stepped into teams mid-sprint to unblock shipping.

I start with a technical audit to understand what's there, what's broken, and what's worth keeping. From there I'll give you an honest assessment: sometimes it's a refactor, sometimes it's a rebuild.

Either way, you'll know exactly where you stand.

That's actually one of the most common engagements I do.

A typical setup is a Next.js web app for the dashboard or marketing site, a shared API layer, and a native iOS app for the end-user experience.

I architect both from the start so they share the same backend, design system logic, and data models. You get consistency across platforms without the compromises of cross-platform frameworks.

Yes. Shipping is not the finish line — it's where the real work starts.

I offer retainer-based maintenance packages that cover bug fixes, OS updates (new iOS versions drop every year and things break), performance monitoring, and incremental feature work.

Most of my long-term clients started with a build project and stayed for maintenance. It's the smartest way to protect your investment.

With 40+ apps shipped through App Store review, I've seen pretty much everything — approvals in 24 hours, rejections over obscure guideline interpretations, and multi-round back-and-forth with the review team.

I know how to write metadata, structure entitlements, handle in-app purchases, and navigate edge cases like streaming rights or health data. I also know when to push back through the appeals process.

On top of that, thanks to years in the Apple ecosystem and my involvement in the WWDC community, I have direct connections to Apple's WWDR and App Review teams — an invaluable resource when you need to escalate, clarify a rejection, or speed up a time-sensitive review.

Most developers don't have that line. If your app got rejected and you're stuck, I can probably help.

Experience & context

Quite a few: fintech (Alma), media and sports streaming (Free Ligue 1 for Iliad), health and wellness (Rester Jeune, Kenko), HR and recruitment (Jobreel), venture capital tooling (Edda), AI-powered products (Reve.com, Leadstar), accounting (Strattt), and more.

The common thread isn't the industry — it's ambitious teams building products that need to be fast, polished, and scalable from day one.

Over 40 apps shipped to the App Store and beyond — collectively downloaded more than 400 million times.

Three of those made Apple's App of the Year lists.

Some were solo builds for early-stage founders, others were large-scale projects with teams of 20+. Every single one went through my hands from architecture to release.

All three — only the shape of the engagement changes.

I've built MVPs for pre-seed founders, delivered production apps for Orange, Iliad, and Airbus, and worked to the standard of exigence houses like LVMH and Chanel expect.

Startups need speed, pragmatism, and someone who can wear multiple hats. Enterprises need clean architecture, documentation, and smooth integration with existing teams. Luxury houses expect craft, discretion, and zero compromise on detail.

I adapt to what the project actually needs.

Lille, France — one hour from Paris, London, and Brussels by train.

Most of my work is fully remote with clients across Europe and beyond. When it makes sense I'll travel for kickoff workshops, team sprints, or key presentations.

I've been working this way for over a decade and have the setup, the discipline, and the timezone flexibility to make it seamless.

Yes, selectively. I'm an active angel investor and I advise a handful of early-stage startups — usually at the intersection of mobile, product, and go-to-market.

My sweet spot is founders who have a strong vision but need help turning it into a shippable product.

Sometimes that means writing a check, sometimes it's advisory on product and tech strategy, and sometimes I end up building the first version myself.
