I help tech companies build Rails apps that make their users (and their CFO) happy.
Over the past 8 years, I’ve built features – with small and mid-sized teams – generating six-figure revenues and serving tens of millions of users.
Do any of these sound familiar?
“Our complex features keep getting pushed! And again!”
No worries! Hand me your problems and I’ll babysit them from specification to production.
As the world’s third-largest 3D printing marketplace, Cults gets A LOT of traffic every day (think 200,000+ daily visits).
To keep search snappy for users, I helped Cults migrate its high-traffic pages to an open-source search engine AND built a unified filtering system, so users can dig through 3.8M+ designs in a blink.
Cults now handles 8M+ searches per day with 95% of them returning in under 200ms.
“Every change breaks something else!”
Say no more! I specialize in fast-paced domain modeling and codebase consolidation.
Evalmee was an edtech start-up with a grading problem. Their calculation engine was producing unreliable grades and forcing developers to fix corrupted data in production.
I untangled that beautiful mess and wrote a full test suite – TDD-style – making sure we could trust the output AND add new requirements in a jiffy.
Incidents have been non-existent since delivery — an estimated 200 hours saved each year.
“Can we actually trust this AI-generated code?”
I get it! AI makes your team move FAST! But for critical parts of your codebase, you want top, not slop.
Même Pas Cap! was relying on manual QA only and releasing anything critical was taking forever.
I wrote their first automated tests by hand to establish patterns and standards that’d work for the team. Then, I distilled what I learned into a shared rulebook for humans and AI agents.
The 10 most critical paths went from 0% to 95% coverage in 2 months and the whole team now writes reliable tests at speed.
“Why is this taking SO long?!”
Developers get a bad rep for their communication (or lack thereof), but I’m fluent in both XML and ROI.
Whatever team I’m embedded in, I share progress updates and the occasional technical setback in plain language with colleagues and stakeholders. I’ll communicate clearly with you, whether you’re technical or not, from early plans to post-release.
I record so many demo videos that you’ll soon be calling me your new favorite YouTuber.
You can focus on growing the business with an extra slice of peace of mind.
How I work: five principles
01 From problem to production
I’m a product-minded engineer who doesn't just ship code. I like to start with a customer pain point, bridge knowledge across teams and ship a working solution. Then, I stick with it until it runs smoothly in the real world. Bring in the problem, I'll handle the follow-through.
02 Better done than perfect
I prioritize working and reliable solutions over sophisticated ones. They’re not fancy, sure, but they create momentum. Shipping early and often creates real value. Building is thinking, and your users are your best beta testers. We build with them, not just for them.
03 Deep dive and deliver
Sometimes, good enough ain’t good enough. The problem is complex, the bug ambiguous. That’s when I switch into research mode: I dig into docs, test edge cases, and compare approaches. Every task is a learning opportunity for the whole team, so you’re not just getting code, you’re getting a clear path forward, with a rationale and the next steps ready.
04 Great communication, not just technical solutions
I’m fluent in both XML and ROI. I’ll communicate clearly with you, whether you’re technical or not, so you always know what we’re solving, why it matters, and how it’ll help your business.
05 You know your business
Let’s be real, you know your customers better than I do. Together, we partner to turn your knowledge into tech that’ll make your business move forward. One problem at a time.
Here what folks say about my work
I brought Rémi into our team to help us speed up development across several projects.
Among them: an urgent migration of the system that generates all our invoices, setting up a full automated test stack so we could ship to production with peace of mind, and the list goes on.
Working with Rémi was a real pleasure!
Yves Trochery, CEO of Meme Pas Cap
Rémi joined our tech team to bootstrap our test suite (and handle our more complex features development).
The result: the 10 most critical paths of our web apps are now covered.
I enjoyed the year and a half we spent working together. Rémi gave us great advice, helped us explore new techniques and, above all, improved our codebase.

How I usually help
My typical contributions include:
- designing and implementing features,
- writing specifications,
- codebase consolidation,
- shipping APIs used by millions of users,
- increasing code coverage,
- interacting with databases,
- troubleshooting,
- mentoring junior developers,
- documenting practices and processes,
- and so much more.
My rates
I typically work with open-ended, ongoing contracts at a daily rate. Depending on your project, though, I also offer flat rates for projects with fixed lengths and defined deliverables.
My rates vary based on the scope of the project, and the type of company. Get in touch to discuss your project, and we’ll figure out what works best for you.
Location
I work (mostly) remotely. I’m based in the South East of France, a 3-hour train ride away from Paris. Always happy to hop on a train to come say hi once in a while.
Work history
I’m currently working with Cults, the world’s third-largest 3D printing marketplace.
Previously at Même Pas Cap!, Evalmee, Nextory, Hosman, and Le Wagon. For more details, see my CV.
