Based in Zurich, Switzerland

Hi, I'm
Stéphane
I build Products that hold up.

10+ years of experience in web & mobile development, IT project management, digital marketing and business analysis with a growing focus on cybersecurity and AI.
I work on products where reliability, clean code, and performance matter as much as the feature itself.

I like simple code. I like systems that don't fall over at 3am. I like it when things actually work.

Available for freelance & contract missions

What I actually do

My official excuse to geek out over code, architecture, and systems, while pretending it's very serious work.

WEB & MOBILE DEVELOPMENT

Building apps, showcase websites and e-commerce platforms from the ground up, clean code, solid architecture, real deadlines.

DIGITAL MARKETING

Growing visibility and driving traffic that actually converts, SEO, paid campaigns and social media that speak to the right audience.

SEO Google Ads Social media Content strategy

PROJECT MANAGEMENT

Planning, coordinating and delivering IT projects end-to-end, from scope and budget to execution and stakeholder buy-in.

BUSINESS ANALYSIS

Turning business needs into clear, actionable specs, the bridge between what stakeholders want and what actually gets built.

CYBERSECURITY

Finding the weak spots before someone else does, security audits, penetration testing, and turning users into the first line of defense.

AI & AUTOMATION

Putting AI to work, automating repetitive tasks, engineering prompts that actually deliver, and producing visual and video content at a pace no single person could match alone.

Selected work

A few projects that show how I think about product, code, and shipping something real.

ABOUT ME

I'm a fan of design and new technology. I work independently and autonomously, driven by turning ideas into something real.

Outside of code, I'm an amateur triathlete, solid on the run, decent on the bike, and admittedly slow in the water. I'm also into video creation and concept design.

Rigorous Curious Pragmatic Attentive Solution-driven Creative



Certifications


I keep investing in new skills from IT governance frameworks to today's AI tooling, including hands-on work with Claude Code and Claude Cowork.

What I believe in

The principles that guide how I code and collaborate.

01

Simple code always wins

Complexity has to earn its place. A system you understand is a system you can evolve.

02

The user before the tech

The best code in the world is worthless if it solves the wrong problem.

03

Automate rather than repeat

If I do it twice, the third time becomes a script. Time saved is worth more than immediate perfection.

04

Communicate as well as I code

Explaining the why behind a technical decision matters as much as the decision itself.

What I'm looking for

Real impact

Technical decisions measured by their effect, not by how much code got shipped.

True collaboration

A team where dev, product, and design work as peers, not in silos.

Technical rigor

Environments where code quality and technical debt are taken seriously.

Complex problems

The more ambiguous the problem, the more interesting the work becomes.
