My expertise
From the first line of code to production, and well beyond.
Shipping software is only the start. Keeping it fast, secure and useful month after month is where the real difference is made.
Maintenance and production
Preventive and evolutive maintenance, monitoring, fixes, upgrades. I know what it takes to run an application every single day without downtime.
Applications already live
Hand over my app →Cybersecurity
Audits, hardening, access and secrets management. Expertise I'm building through an MSc in information systems security and apply to every product I ship.
Teams handling sensitive data
Request an audit →Architecture and product
Scoping, technical choices, roadmap: I help you build a product that handles today's load and can keep evolving tomorrow.

Leadership
A developer who also knows how to lead teams.
I run Omnitrade, my digital solutions studio, and since 2023 I've been Executive Managing Director of a private educational institution. Governance, budgets, teams, partners: I know the trade-offs a leader makes every day.
That perspective shapes how I build. A good tool is measured by what it brings to the organisation, what it costs, and how easily people adopt it.
Lead
- Governance and strategic vision
- Budget and financial management
- Uniting and energising teams
- Organisation, quality and continuous improvement
Teach
I coach technical teams and students in web development, architecture and security best practices, with one simple goal: that they leave fully autonomous.

How I work
How we work together.
No jargon and no surprises at the end. You always know where things stand, and the work carries on after launch: that's the Kaizen mindset.
- 01
We talk
I take the time to understand your business, your constraints and what you really expect from the tool.
- 02
I send you a proposal
A clear scope, timeline and budget, agreed with you before a single line of code is written.
- 03
I build, you follow along
Regular deliveries: you watch the product take shape and share feedback as we go.
- 04
We go live
Secure deployment, monitoring and onboarding for your teams.
- 05
We keep improving
Preventive and evolutive maintenance in the Kaizen spirit: every week, the tool gets a little better.
My journey
Code, ship, energise, and do it better next time.

The blog
All articlesWhat I learn while building.
Development, cybersecurity, product and entrepreneurship. Hands-on lessons drawn from my own projects.
Get the next articles.
One email when a new article, job or product announcement is published. Once a month at most.
What kind of projects do you take on?
Web and mobile apps, internal management tools, SaaS platforms, taking over and maintaining existing applications, and security audits.
How much does custom software cost?
It depends on the scope. After a first conversation, I send you a detailed proposal with budget and timeline, so you know exactly what to expect.
Can you take over an application that's already live?
Yes, it's a big part of my work. I start with a review of the code, infrastructure and security, then tell you honestly what can be kept, fixed or rebuilt.
Do you handle maintenance after launch?
Yes. Preventive maintenance to avoid outages, evolutive maintenance to follow your needs, and quick fixes when incidents happen.
How do you approach security?
From the design stage: access control, data protection, up-to-date dependencies, backups. I follow OWASP recommendations and ISO 27001 principles.
Do you run training sessions for teams?
Yes, on site or remotely: web development, security best practices, digital tools. Content is tailored to each person's level.
