Hi, I’m Kevin.
I’m a founder who still likes to build things himself. Eversa is my main work these days; I also run Ikarus and started Strife. The rest of the time you’ll find me on a rock face, an autocross course or a piano bench.
- Founder: Eversa is my main work. Ikarus is the studio I have run since 2019.
- Climber: Paroi Éléphant, Kamouraska, Banff. I like the hard routes.
- Racer: Autocross in a Ford Focus RS. Two class wins in 2024.
- Traveller: From Iceland to the Caribbean. Seeing how the rest of the world lives matters to me.
- Diver: Scuba diving in the Turks and Caicos and off Cozumel.
- Pianist: Classical, learned one slow bar at a time.
- Teacher: Two years teaching at La Cité collégiale.
- Esports: Strife, the Counter-Strike team I co-founded in 2021. We won Fragadelphia 16 and played at DreamHack in Sweden.
My technical side.
- I listen. A project starts with you talking and me taking notes. What you need comes before what I would like to build.
- I research. Before I touch anything, I find out who it is for, what exists already and what has been tried.
- I analyze. I read the numbers before I decide, and again after, to see if I was right.
- I care about craft. Quality matters to me in every part of a business: the code, the screens, the words, and how a customer gets answered.
- I notice details. A button two pixels off, a slow page, a sentence that doesn’t sell. I see them, and they bother me until they’re fixed.
- I improve things. Give me your website, your sales page, your campaign or your product. I find what holds it back and I make it better.
- I build. More than eight years building software from the ground up, from the first commit to the launch.
- I keep it live. Launches, deploys and database migrations on platforms with millions of active users, while they stay online.
- I run a business. I founded Eversa and I run it, so I treat your budget and your deadline the way I treat mine.
I have worked on: Product launches, Microservices, Mobile apps, Websites, Platforms, Checkout, Crypto, Millions of active users, Database migrations, UI and UX, Sales sites, Sales campaigns, Infrastructure, Scaling, Live operations, Support, Analytics, Team management.
Design
The part your customers judge you on. I design it and I build it, so nothing gets lost in between.
- Product and UX design
- Sites that sell
- Motion and polish
Build
From an empty repository to a product in production, more than once.
- Architecture and audits
- Product builds
- Rescue missions
Security and compliance
Customer data is a responsibility before it is a feature. I build as if I will be the one audited.
- Security reviews
- Data protection
- Compliance
Run
Deploys, monitoring and database migrations on platforms that are live and busy, for several customers at once.
- DevOps and deploys
- Monitoring
- SEO and performance
Lead
I run a company too. A deadline is a business problem, and I stay on a hard one until it ships.
- Fractional CTO
- Tech lead for hire
- Hiring and mentoring
I’m a tech nerd. I love this work, and that is why it gets done properly: I stay invested, I work through the hard parts, and I deliver.

Great, you got to the top with me.
It’s late now. That was a tough one, right?
If your next project looks just as steep, I’d like to rope up for it. Leave your name and a line about what you’re building, and I’ll write back.
